It is a product of the QwensIllinois Glass Company, developed by Owens Illinois engineers and made by compounding raw materials that Owens-Illinois has worked with for more than half a century,Tt is the result ot many years' work to produce a fireproof insulating material having light weight and good structural strength. Although made hy the manufacturers of Insulux glass block, Insulux insulating block is not a glass material and is not to be confused with glass block. It is a crystalline compound made of sand, lime, asbestos and other materials. It is white in appear"it rice. Tbour ninety per cent of its structure is com posed of air cells, too tiny even t<> be seen by a microscope. It is exceptionally strung fur its weight, in fact is outstanding in its combination of light weight and strength. Although a noii-organic ma terial it can be Cut. sawed and otherwise worked much the same as fibrous boards or slabs. low Donsity Insulux insulating block has a density of approxi mately 13 pounds to the cubic foot, or just slightly more than a pound to the board foot. This is m aid in handling, shipping and application, On equip ment such as ships and locomotives jc contributes substantially to weight reduction. Crushing Strength Crushing strength is unusually high for a rninvral product of such light weight, The block readily withstands compression comparable to dint of a man walking on it or even to that of a heel ground into it. High ffexurof Strength Flexural strength is high, fiO pounds per square inch for a 13-pound density, as compared with a normal requirement for a material of this kind of approxi mately three times the density or 39 pounds. This strength at this weight is an aid to easy IntndUng and application. It also contributes to long service ami low maintenance. Relatively fnsofub/c in Water Because of its cellular structure with cells intercom municating, Insulux Insulating block will absorb moisture when immersed. However, its structure is not injured by saturation with water, hot water, or even steam. It is almost completely insoluble in water--can be boiled for hours wiji almost no loss in weight or strength after being dried our again. Also its srrength while wet. although redact'd, is still substantial. It can be submerged in boiling water for several days and while still wet and hot CopyfJgM IP-44 Cw*fl.l|Nnoii Gloil CompOliy.

Low loss in Weight t,oss in weight In tests that simulate long applica tion to hot surfaces is low when compared with most other mnrrmls. Also, such loss in weight as is experienced On Continuous exposure to heat, throughout the range of temperatures for which the block If recommended, has remarkably little effeer vii it. The block remains strong, free from excessive powdering which usually accompanies calcination, 01 034 0067 18-50-442 3M-Pfin1.fi In U.5.A. MHffltN II I III mu ........... ft U I ? P. 09 IRKABLE COMBINATION OF ADVANTAGES 71 *HA$ WIDE RANGE OF USES and changes little in surface hardness. liven standard tumbling tests run after prolonged heating produce but little crumbling or breakdown of the material. low Shrinkage Shrinkage, which is closely related to loss iu weight is low as will be noted from the table on the left hand page. This helps to solve many problems. It helps produce a good job because low shrinkage at high temperatures cuts to s minimum any tendency to open up at the joints. Encourages Good Application Work Individual blocks arc noticeably clean cut and trim as to edges, ends and corners. Their strength helps to keep them this way until they get in the hands of the applicator, and once in his hands these dean cut pieces help hint to turn out a good looking finished job. Finishes that go over the block whether cement or other types, such as doth, canvas, etc,, can be applied with a minimum of wrinkling and irregularity. Good Insulation Value Insulux insulating block hat been developed to pro duce the best combination of advantages obtainable in fireproofness, strength, durability and insulating values. Although some materials may excel it in a single individual quality, probably none excels it in this combination of desirable qualities. Its con ductivity coefficient or k, given in the Curve here, places it among the more efficient insulations for medium high temperatures. Also Its conductiv ity curve is relatively flat and straight, indi cating that it not only does a good job on tempera tures typical with low pressure steam or even hot water, hut also on superheated steam. Also its k value is conservatively stated. Actually, the values shown arc taken as the highest of several from tests runby different well known laboratories. It is signifi. cant too that its k value tends to improve (that is. to drop) after the material is in service on hot surfaces. No Binder Insulux heat insulation is actually its own binder. It is a uniform compound or series of compounds produced by reacting together the raw materials that go into its manufacture. These materials with some asbestos added for reinforcing make up the fmisheTpToduet. "The performance of the hnisRcB product is' therefore the performance of the ma terial itself, not limited as to temperature, water solubility or nthuewise by the limitations of a binder added to the insulating material. Sites Insulux insulating block is made in a Standard site 6 x .1(5 inches anti in thicknesses of 1, Hi and 2 in. Greater widths are available on special order. If there is a special problem that requires larger sizes and higher densities and strengths, that justify special manufacture. Owens-Illinois engineers arc available for discussion of your problem. fUAllAmj-iuu u iMAfun t P. 10 VERSATILE MATERIAL Has Many Uses! Light weight, strength, good insulation value nod capacity to meet severe service conditions give Insu. lux insulating block a wide range of use. Through its recommended temperature range it is adapted to use throughout the industries in which hem insula tion is required. Central power plants and related distribution sys tems subjected to conditions of vibration, humidity, and periodic or occasional eveles of saturation and drying will find of practical value the capacity of this block to resist deterioration under such condi tions. The history of the oil industry is one of rapid and radical changes both in processes and equip ment, with a trend toward higher temperatures and more Stringent requirements placed on its equipment and insulation. Ruggedness and strength of Insulux heat insulation coupled with its good insulating value help it to meet oil industry requirements. These advantages help to secure clean-cut efficient installations on new work and also to provide greater salvage of usable material when subsequent changes become necessary, Equipment manufacturing industries find Insulux insulating block a dependable material because of its strength and light weight and because of its capacity to give continuous and efficient service at the top temperatures recommended here. Some of the typical recommended uses arc for installations on Construction or equipment such as the following: Breechings Boiler Walls Hot Air Ducts Tanks Towers Melting Tanks Evaporators Heat Exchangers Condcnsorj Lehrs Ovens Heat Treating Furnaces Turbines Chilling Pits Pit Covers o dQltiencict --Insulux Heat Insulating Block o Heat Loss--and Cold Surface Temperatures -- Insulux Heal Insulating Block.

Simpson, Newark. Ohio, assignor J& Ovrens-Illlnou Glass Company, a corporation oifoina^------- Application May Z2, 1957, Serial No. W.Zit 11 Claims. (Cl. U7--53J The present Invention is a novel combination ofjssbestas and glass fibers Tor use in yarns, Inter- woven cloTn, knitted articles, Felts, or other fab ricated articles, particularly adapted for elcctrt* . cal Insulation, packing material, gaskets, frlc- " tlon elements, heat Insulation, cements, fillers In fabricated boards, Acoustical insulation, battery separators, and various other uses, Doth glass and asbestos fibers,taken by them* 10 selves have inherent shortedmincs which limit their appitcutlon ana use fn Industry and com merce. Asbestos, for example. Is composed of rel atively short and weak fibers which prevent them from being fabricated into strong yarns, cloth, and fabrics. Short asbestos fibers have not been fabricated Into any type of yarn or fabric with out Use incorporation of organic fibers such as cotton, or the tike, which serve to hold the short asbestos fibers together. Fine wires have also been used for this purpose, Both of these odd!- - Uottal components, huwever, have definite short comings ami disadvantages, as, for example, the admixture of (.(.-anJc cotton fibers or the like Immediately brings dawn the temperature or fire resistance of the fabric to that of cotton. The ln"a corporation of wires, on the other nand, prevents the use of the product as an electrical IhjuJotlon, The use of metal wires or the like ti also inferior from the point of view of pliability, flexibility, ,0 cost, case of manufacture, and feltabiilty between the metal wires and the asbestos. Ordinary glass fibers also have serious short comings and limitations in their fabrication into woven fabrics. These limitations are generally ... traceable to the Inherent nonstrctchabllity of glass fibers, the strctchablllty being limited to one or two percent or so. according to the exact fiber diameter, the type of elms*. and the perfec tion of the fiber. When a series of gU threads . are fed into a conventional loom to form a worp, the sudden stresses and loads Inherent in a loom are concentrated In the tightest threads which cannot carry the liitlre load themselves and, therefore, tend to break rather than stretch. 45 Of course. Whenever an end or thread break* In a loom. the entire operation must be stopped and the broken end fed through again before the weaving may be resumed, A similar condition exists When ordinary Class yarns or threads are 50 fed into the Weft or flllcr of a fabric, Moreover, fabrics composed solely of glass fibers, especially It made particularly sheer or thin, have consid erably less resistance Vo folding Or creasing than ordinary fabric*, If the fftbrlO ll flexed 10 ny gg degree, or creased, it tends to crack or break and fall apart. Men ly rcciucing the diameter size of the glass fibers docs not necessarily cure this condition became, as the fiber diameter is re duced, so Is the radius of curvature around which the fiberj have 10 be bent, That is to say. the . fibers of the warp are bent around the fibers of thfl flJlcr nod U they are bent around a small enough radius of curvature, the fibers of the warp are crocked and broken. The same condition, of course, obtains when the fibers of the filler arc ]0 bent around the fibers of the warp. Another difficulty caused by the Inherent non- strotchablilty of the glass fibers, I* the concen tration of stresses Induced In the outermost fibers at a fold or flexure in the cloth. The glass fibers ,s being more or less unyielding in and of them selves, prevent the load caused by a flexure or creasing from being distributed uniformly throughout the body of fibers to permit their full combined strength to be brought Into play, I have discovered that the above mentioned in- *v dividual shortcomings of the asbestoa and glass fibers may be overcome by a combination of the two, and that a superior product, having prop erties sui>crlor to any of tire Individual properties of the ingredient*. may be produced by a com- 25 binatlon of the two type* of fiber*. An object of the Invention Is the provision of a fabric which Is flexible, coft, strong, and com pletely fireproof. Are resisting, rot proof, and chemically resistant. Another object of the invention Is the provision of a fabric composed of Inorganic fibers which may be fabricated into felt or Interwoven tape suitable for electrical, heat and/or sound insula- J3 tlon. Another object of the Invention Is to utilize the softness, pliability and yicldabllity more naturally Inherent in the asbestos fibers in combination with (jlojs fiber*, which arc much stronger and longer a than the usbestos fibers. The individual class 40 fibers are sufficiently fine and long so that they may be intertwisted or Intcrfeltcd with the as bestos fibers to form strong yarns which may be safely subjected to the rigors of n conventional , loom. Tiro asbestos fibers serve as cushions for the adjacent glass fibers to assist In the distribu tion of loads throughout the glass fibers, and to loud yleldoblllty and pliability and strength to the final fabric. s0 In addition. If the glass fibers have been Inter twisted or Intcrtclted with the asbestos fibers, this.arrangement will prevent the individual ginaJ fibers from being laid out in stmlnht lines, but, On the eontrory, will permit them to assume licit- 55
