JTC:pc Enclosure r CALSILITE CONFIDENTIAL With the support and at the behest of the United States Government which needed to increase wartime production of shipboard insulation materials, in 1944 Ruberoid constructed a Calsilite* plant to manufacture Calsilite* pipe covering and block insulation. The plant was completed in approximately November, 1944. Some limited production of Calsilite* occurred prior to the plant's completion. GAF believes that all Calsilite* production during World War II was for the United States Navy. In June, 1947 the Calsilite* facility was shut down temporarily and all outstanding orders were cancelled. The facility was reopened on July 10, 1947 and operated on a pilot plant basis until March 7, 1949. During this research project period, production was limited and of an experimental nature. Calsilite* was again manufactured on a commercial basis by Ruberoid beginning on March 7, 1949, and then by General Aniline & Film Corporation in 1967, and then by GAF.Corporation from 1968 to October, 1971. Calsilite* was a lightweight, hard, calcium silicate insulation designed to withstand temperatures up to 1250 F. Calsilite* pipecovering was manufactured in three-foot lengths and in varying thicknesses. It was available in half-sectional pieces,^and, at various times, in three-segmental and regular segmental shapes, for assembly around a pipe in single or double layers. Pipe covering normally was provided with standard weight cotton or canvas jackets applied with silicate of soda. No "T's," elbows or joints were produced. Flat Calsilite* blocks were manufactured, at various times, in 18 or 36-inch lengths, in widths from 3 to 36 inches, and in thicknesses up to 4 inches. Six-inch wide curved segmental blocks, capable of contouring more easily for insulation of large pipes and circular vessels, also were available. Calsilite* was manufactured by a "pan-molding" method until 1964 when Ruberoid began using a "filter-press" method or process. Pan-molded Calsilite* was grayish white and relatively smooth, with some small holes. Calsilite* filter press was grayish white with screen marks on the outer surfaces. Calsilite*-Hi, developed in or around 1960, could withstand temperatures up to 1800 F. In the mid-to-late 1960s, Ruberoid developed Calsilite* SS, an "inhibited" product designed specifically to prevent stress corrosion and cracking of stainless steel piping. In addition to formula changes made in connection with product development, the Calsilite* formula was adjusted often in order to compensate for changes in the quality and availability of raw materials. GAF does not have a complete set of all the formulas used in Calsilite* production nor does it have complete information about the production dates of known formulas. To the extent available, the-mineral and chemical rconstituents and the weight of each constituent as a percentage of all solid constituents in Calsilite* production formulas are listed below, together with known dates of production. 2 1.

KWK and Black Hills bentonite were the two main sources olT.. supply circa 1954. Sodium silicate, also referred to as "silicate of soda" or "water glass", was purchased from Philadelphia Quartz Co. in an N grade (1:3.22 ratio of sodium to silica). r Silica sand also referred to as "silica flour" or "ground silica sand", was purchased from Pennsylvania Glass Sand Co. in Midville, NJ and possibly from South River Sand Co. in the same area. It was a very pure sand with very little staining from organic contaminants. 150 mesh silica sand was used in some pilot plant production (see formula nos. 13-15, below), and 120 mesh ground silica also was used in Calsilite* production at least in September and November of 1954.

(See Formula no. 23, below.) However, the trade name "Celite" also may have been used as a generic term for diatomaceous earth. Dicalite, the tradename for .a fresh water type of diatomaceous earth from The Great Lakes Carbon Co.'s Nevada deposit, was also used in Calsilite* production. Processed Dicalite, to which sodium silicate had been added, may have been used, as well as unprocessed Dicalite. Some diatomaceous earth also may have been purchased from one or more other producers. Ca(OH)- Mg(OH)-.

Asbestos Paper Asbestos paper was designed to be used alone or in the manufacture of other products. It was manufactured in various thicknesses, according to customer specifica tions. Asbestos paper had a temperature limit of 250 degrees F. Its primary constituent was chrysotile asbestos, generally a mixture of grades 5 to 7. Other constituents included sulphite pulp, diatomaceous earth and starch, although in the early years of manufacture this product may have consisted only of chrysotile and starch (which was sometimes in the form of tapioca). The following formulas for asbestos paper products for the years 1960-1981 were derived from examinations of thousands of "Beater Furnish Reports" and "Commodity Specification and Cost Sheets", each of which reports the mix of constituents during production of a specific product on a specific day during the years 19601981. (The available "Beater Furnish Reports" and "Commodity Specification and Cost Sheets" and are not complete for that entire time period.) The percentage for each constituent in a given product is expressed as ahaverage of all available "Beater Furnish Reports" and "Commodity Specification and Cost Sheets" for that product. In addition, the range of variation from the average is expressed as a plus or minus factor for each constituent. r 15 1.

Ro-llboard - Regular 1/8" Commercial Rollboard: Circa ii/19/33 chrysotile tapioca enzymes 92.3 % 1.7 % 29.5 cc - Trace This Rollboard was made by plying two or more sheets of .035 - .038 asbestos paper, 36-3/4% wide, on the plying machine in the Millboard Department. Silicate of Soda was used in plying the 2-ply 1/16" Rollboard. Rye Flour was used in plying the 3- and 4-Ply Rollboard using the following formula: 28 Lbs. Rye Flour 30 Gals. Water 1 Gal. Silicate of Soda 7 Lbs. Pearl Starch Millboard Millboard was a stiffer product than asbestos paper or rollboard and was manufactured in sheets of varying thicknesses according to customer specifications. Millboard consisted generally of chrysotile asbestos, (usually grades 5D, 5R and 6D), sulphite pulp and often other constituents, bonded with Portland cement and/or starch. In later years, at least as early as 1974, latex was added as a binder. The following formulas for millboard products from the years 1960-1981 were derived in the same manner as the GAF asbestos paper formulas for those years: 1.

Corrugated Asbestos - Paper Corrugated asbestos paper was designed to be used alon^. or in the manufacture of other products. It was made in three types: 1/4 inch thickness per ply (4 plies/inch); 1/8 inch thickness per ply (6 plies/inch) and 1/16 inch thickness per ply (8 plies/inch). It was manufactured by adhering 36" to 37 1/2" wide flat sheets of asbestos paper (usually six pound paper) with silicate of soda to sheets of the same paper which had been corrugated using characteristic "Roman Arch" shaped corrugations, 26-28 to the foot. Its constituents were those ' of the asbestos paper from which it was constructed.. Corrugated asbestos paper was sold in 250 and 500 square foot rolls. 25 I Air Cell Air cell was a corrugated asbestos paper product manufactured from 1928 to approximately 1958. It was constructed of layers to the thickness specified by the customer of 36 or 37-1/2 inch wide flat asbestos paper which was adhered to corrugated asbestos paper with silicate of soda. The corrugations of this product had a characteristic "Roman Arch" shape. As of 1938, the corrugated paper component had 28 corrugations per lineal foot. Each ply was 1/4 inch thick and air cell came in three standard thicknesses -- 2-ply, 3-ply, and 4-ply. Air cell pipe covering, sheets and blocks were sold. Often a canvas, cloth or pyroxiline jacket was applied to the outer surface of air cell pipe covering with an adhesive, usually a starch or cereal paste. 2-1/2 brass lacquered bands were provided for each canvas-jacketed section of air cell pipe covering to hold it to the pipe. With the pyroxyline jacket, three 1-inch wide black japan bands were supplied with each section. Air cell had a temperature limit of 250 degrees - 350 degrees F. Prior to 1935, air cell may have been sold only under the name "Celasbestos", which was available in 5, 6, 7 and 8 ply versions as well as 1-4 ply versions. Watcocell Watcocell was a corrugated asbestos paper product manufactured as Watcoce^ from 1928 to 1934, as Supercell from 1935 to 1942 and as Watcocell from 1942 to 1960. In 8-ply per inch Watcocell, the corrugaTTons were 1/16" thick; in 6-ply, the corrugations measure about 1/8" thickness. Watcocell was sold in rolls, sheets and blocks. Watcocell's temperature limit was 250 degrees F. _ Imperial Insulation Imperial insulation was manufactured from at least 1936 to approximately 1960. It had a temperature limit of 500 degrees - 700 degrees F. Imperial paper consisted of two plies of flat asbestos paper which were passed through an indenting roll resulting in a waffle-like appearance with closely spaced square indentations. Imperial pipecovering was wound on a mandrel to achieve the desired thickness and canvascovered. In early years of production, layers of Imperial may have been stapled together or stitched with strands of wire rather than wound on a mandrel. Imperial sheets and blocks were made of layers of Imperial paper glued to the desired thickness with a fireproof glue, such as silicate of soda. This product was sold with a canvas, asphalted felt or pyroxylin jacket. 26 Aristo Insulation The years of manufacture of Aristo Insulation are unknown, except that it was listed for sale in and around 1940. It was a corrugated asbestos paper product with carefully measured indentations and 23-25 laminations per inch of thickness. Its temperature limit was 700 degrees 750 degrees F. The asbestos paper used in this product was treated with a surface treatment, possibly Bennett size. This product was sold in a standard thickness of one inch, but often was used in thicknesses up to and exceeding three inches. Standard canvas and waterproof jackets were available for this product. Sponge Felt Sponge felt was manufactured from 1936 to approxi mately 1960. It consisted of asbestos sponge paper made by imbedding small pieces of sponge into asbestos paper. Its temperature limit was 750 degrees F. It was sold in 36-inch wide rolls, sheets and blocks which were produced in the same manner as Imperial products. Woolfelt Woolfelt, a wool or rag felt insulation manufactured from 1928 to approximately 1959, did not contain asbestos, but was sometimes sold with an asbestos paper liner or backing paper. Tar-lined woolfelt was sold with a tar paper liner which did not contain asbestos. Twin-purpose woolfelt was sold with a liner of asphalt coated asbestos paper. Anti-Sweat Pipe Covering r;-- Manufactured until approximately 1958, anti-sweat pipe covering was intended exclusively for residential use on cold water pipes. At least as early as 1936 this product was composed of an inner layer of asphalt-saturated asbestos paper followed by a ^2 inch layer of woolfelt, 2 layers of asphalt- satuirated asbestos paper, another ^ inch layer of woolfelt and two final layers of asphalt-saturated asbestos paper. The outermost layer had a flap extending at least 3 inches beyond the longitudinal joint. GAF does not know whether a jacket was ever provided with this product. This product was sold in 36 inch wide rolls and had a temperature limit of 50 degrees F. 27 Frost-Proof Pipe Covering Practically nothing is known of this product which was apparently constructed of a layer of felt made from cattle, goat or other animal hair with layers of asphalt-saturated asbestos paper and a layer of woolfelt. Its years of manufac ture, appearance and temperature limit are unknown to GAF. Range Boiler Jacket This product consisted of a series of plies of corrugated asbestos paper built up to the required thickness on Mandrells that were the same size as the range boilers the product was designed to fit. The corrugated paper used was a coarse variety with four plies per inch of thickness. These jackets were furnished in two sections -- upper half and lower half. Five extra-wide bands were provided to attach the jacket to the range boiler. The outside surface was painted or covered with canvas. GAF does not know the years of manufacture of this product. r* 28 / INSULATING CEMENTS 1. 115 Insulation Cement Ilk Insulation Cement was a chrysotile asbestos product which* in some instances, was produced at Rubero id/ GAF's Vermont facility and in other instances was purchased from various other asbestos suppliers and resold. Some of the product purchased from other suppliers may have been milled again at Rubero id/GAF' s Vermont facility prior to resale. Asbestos insulation cements produced at GAF's Vermont facility could generally be distinguished from asbestos insulation cements produced by other manufacturers inasmuch as the Vermont product was a slip chrysotile asbestos rather than a cross vein asbestos and was generally of a lower grade and contained a greater percentage of impurities, such as dirt and rock particles. It is believed that this product was sold from at least as early as 1937 to 1975. It is believed that the "115" designation was employed from approximately 1950 to 1975 and the designation "Grade B" was also employed in years prior to 1950. The basic ingredients of this cement product were: chrysotile determined to pass the 0-0-1-15 Quebec test impurities (dirt, rock, earth) The particular formulas utilized by entities which purchased this product for construction are not known by GAF, but this product was normally mixed with Portland cement, water and/or other substances. 2. 214 Insulation Cement 214 Insulation Cement was also a chrysotile asbestos product which, in some instances, was produced at GAF's Vermont facility and in other instances was purchased from various other asbestos suppliers and resold. Some of the product purchased from other suppliers may have been milled again at Ruberoid/GAF's Vermont facility prior to resale. Ruberoid/GAF's Vermont product was a lower grade cement which contained a greater percentage of impurities, such as dirt and rock particles, making it lightly mottled and giving it an overall darker appearance. It is believed that this product was sold from at least as early as 1937 to 1975. It is believed that the "214" designation was employed from 29 approximately 1950 to 1975 and the designation "Grade BB" was also employed in years prior to 1950. The basic ingredients of this cement product were: chrysotile determined to pass the 0-0-2-14 Quebec test impurities (dirt, rock, earth) The particular formulas utilized by entities which purchased this product for construction are not known by GAF, but this product was normally mixed with Portland cement, water and/or other substances. 3. Calsilite* Insulation Cement Calsilite* Insulation Cement was a combination of chrysotile asbestos fiber, ground Calsilite* pipe covering or block, and Portland and other cements. The basic formula of this cement product was as follows: ground Calsilite*pipe-covering orblock 36.8 chrysotile 45.0 Lumnite cement, an aluminumsilicatecement 13.6 (approximate formula: 60% calcium aluminate, 12% calcium silicate, 13% ferrite, 15% ferrous oxide) Portland cement 4.6 Prior to 1954, Calsilite* Insulation Cement of the following formulations may have been sold: ground Calsilite* pipe-covering or block Vermont 7k chrysotile calcined gypsum 41.0 49.0 _ 10.0 --- and ground Calsilite* pipe-covering or block Vermont 7k chrysotile 45.0 55.0 t- It is believed that this' product was made with Vermont-produced asbestos and thus contained certain impurities, such as rock, dirt and earth particles. This product was never widely or frequently sold. To the extent such sales took place, they ceased completely in or around 1960 . 30 4. Other Insulation Cements v In unknown years prior to 1955 which varied by product, Ruberoid listed for sale the following other insulation cements. Except as stated below, little is known about these products, including the specific years they were offered, the constituents and, except as indicated, whether or not they were manufactured or produced by Ruberoid. a. Grade AA Insulating Cement - Grade AA was manufactured by Ruberoid using a high grade of pure asbestos fiber together with suitable binding materials that had low conductivity.

T. - High Temperature Cement - This cement was designed to withstand temperatures of 1600 to 1800 degrees. This material was not designed to be used for finishing purposes. f. Grade 203~Insulating Cement - Grade 203 had a screen test of approximately O-Q-8-8 which was intended to result in a light, fluffy cement. It was practically free of grit and dirt. The formula for this cement is unknown except that in 1938 it consisted of: chrysotile clay Portland cement 68.5% ~27.0% 4.5% Its temperature limit was 1200 degrees F. g. Grade 016 Insulating Cement - This 100% chrysotile cement had a screen test of approximately 0-0-1-16 which made it the lowest grade cement sold by Ruberoid/GAF. GAF knows nothing about this constituent, or about "Guaging Cement" (see formula d, below) except its name as shown. 32 h. Satin Finish Cement - This product consisted of the following formulation: chrysotile Portland cement Medusa cement 87% 10% 3% i. Grade A-ll Insulating Cement - This product consisted of vermiculite, chrysotile, and binding sub stances. It was recommended for temperatures up to 1500 degrees F, or 1800 degrees F if the applicator did not intend to reclaim the material. Grade A-ll was designed to be an insulation material, not a finishing cement. j. Coverkote - Coverkote was designed to be a weatherproof coating or insulated surfaces, rather than an insulating cement. It was a combination of emulsified asphalt and 25-28% chrysotile. It was a black plastic material particularly designed for protection of insulation on large tanks and vessels and for insulated equipment such as smoke breechings and ducts. The temperature limit for Coverkote was 400 degrees F. k. Rock Wool Cement - Little is known about this product which was apparently available from Ruberoid in the late 1940's and early 1950*s. It consisted of a mixture of rock wool and chrysotile asbestos and had a temperature limit of 1500 degrees F. r* 33
