Williams - Industrial Hygienist Gentlemen: Thank you for your inquiry about asbestos substitutes through Occupational Hazards magazine. Our flyer is enclosed showing our abilities. We believe we have a greater knowledge of the materials available that can substitute for asbestos in high temperature areas than any other comoany in the world. Our field engineers have several years of exoerience in solving special problems of application. If you have specific problems to be solved, please write to me. Describe the problems, for example: a) Temperature b) Mechanical strength c) Wear resistance d) Estimated usage If the answers seem obvious we will send samples for your consid eration. If the problems are complex we will have a sales engineer call to discuss them. Very truly yours, J........ ...........

Responsible plant managers are eliminating Asbestos and Asbestos products from their operations. Finding substitutes for Asbestos that will do the Job without exceptional added costs Is often difficult. We offer a complete range of products with the applications, these products. 1. Die cut gasket shapes. 2. Machine parts from dense boards. 3. Fabricate boxes, unusual shapes. 4. Sew with glass thread. 5. Make special curtains or blankets. 6. Produce tubes and pipes to your size specifications.

In rolls 1/4", 1/2", 1", thick. From m to 6 Ib/cu.ft. density. Densities are 8 and 14 Ibs/cu. ft. Used in high temperature gasketing applications requir ing more body and rigidity of the gasket. Good for hold ing vacuums or pressures. Also use as insulating covers and plates. Used to gasket molten aluminum, magnesium, zinc and other low temperature applications. Not normally used when long life is required. 2. HIGH TEMPERATURE FIBERSEAL FELTS For continuous use to 2300F (1260C), for short per iods to 3000#F(1650#C). > /` In rqHs 1/4*. *** From 3 lb. to 8 ft>./cu. ft. (tensity. Used in all molten meted applications to gasket launders, ` troughs, stopper rods, and other items in contact with the molten metal. ; 6. FIBERSEAL MEDIUM TEMPERATURE COMPRESSIBLE BOARDS For continuous use to 1800'F (990C). In sheets 1/8", 1/4", 3/8", 1/2" thick. Also 1" to 4" In 1/2" increments. Sheets to 1/2" thick in sizes 36" x 40" and 40" x 48". Thicker sHeete in 24" x 36" size. These are less expensive than the high temperature boards. Typically they are notasstrong.. Uses are basically the same as the high temperature' boards. Insulating blankets and wraps for casting molds, pipes, sound absorption, heat shields, etc. 3. FIBERSEAL FABRICS For continuous use to 900F (480C), short period use to 1400*F (760C).Some to 23008F (1260C). in rolls 50" and 60" wide. Used as high temperature curtains for air control, d(apes for protection from welding sparks, shrouds to cover ductwork joints. Anywhere a completely flexible material is needed in hightemperature conditions..^ We sew these fabrics to custom shapes or fit with grom mets to hang as a curtain. 7. PYROTHERM DENSE BOARD . For continuous use to 1300#F (700C), for short per iods to 2000F(1100C). Density 36 Ibs./du.ft. In sheets 4' x 8'. Thicknesses 1/2", 3/4", 1"; 1 Vi", 2". This is a hard, physically tough board, it is highly insul ating.^ frte easily cut, machined, screwed, etc. about like wood. In foundries it is used for blow plates in core making machines aind for bottom boards in sand casting. It is also used to cover felt insulation to make wearresistant insulating pads for various uses. 4. FIBERSEAL PAPERS For continuous use to 230DF (1260C), for short periods to 30dd?F (1650C). In rolls up to 48" wide. Thicknesses of .040", .080", and. 10". Used for high temperature gaskets, hot top linings, ingot mold linings, apd other applications around molten metals 8. FIBERSEAL HIGH TEMPERATURE ROPES For continuous use to 2300F (1260C), for short per iods to 3000F(1650C). Density-About 10 Ibs./cu. ft. Diameter - We can produce nearly any diameter. Available with wire mesh coverings to result in abrasion resistance. Prices on wire meshes wary widely and .jmusi';b de^^ temperature con ditions. 5. FIBERSEAL HIGH-TEMP COMPRESSIBLE BOARDS For continuous use to 2300F (1260C), for short periods to 3000F (1650C). In sheets 1/4", 3/8", 1/2", 3/4", 1", 1 Vi" thick. Sheet sizes vary to maximum of 4' x 8'. Used anywhere heat sealing is required - around fur nace doors, cover plates, oven lids, etc. Used for vacuum seals on crucibles, calking joints, on pressure vessels, pouring ladies, etc. The prices on our high temperature ropes are usually much lower than others available.
