Dear Mr. Bees: skr t 30 co-v yyr- G KmC R-r Warren Anderson has identified the critical issue facing the chemical industry "JiO-'N < Z -f* as "public ;onfidence the safety and integrity of plants and processes". The, Environmental Protection Agency has mandated the removal__ an d discontinuati r of___a_ssestos use in all IJ.S. manufacturing facilities to be c5mpleteF~within ten years Jt is important for Union Carbide o take a position of leadership in replacing asbestos sealants in all of our manufacturing facilities. The Specialties Products Group manufactures GRAFOIL Flexible Graphite for use in both compressive packing and gasketing applications throughout the chemical industry. GRAFOIL has established a lengthy track record of superior sealing and safety performance in the chemical industry. All major chemical and refining companies are today using GRAFOIL in an increasingly broad range of gas and fluid sealing applications. Unfortunately, we have been advised by our own chemical plants that they will continue to use asbestos as long as it is available. This position is harmful to our efforts to expand the use of GRAFOIL throughout all fluid process industries; Union Carbide is trailing industry standards relative to asbestos replacement. Union Carbide's present position not to replace asbestos certainly cannot "improve public confidence in the safety and integrity of (our) plants and processes". Your support in rapidly replacing asbestos packing and gasketing J with GRAFOIL fluid sealant products will certainly help to improve sealing \ performance in cur chemical and gas production processes. It will also j contribute to Union Carbide's leadership position in terms cf public ' confidence in our commitment to plant and employee safety.

Since oicneecng the development of GRAFOiL Flexible Graphite, Union Carbide has been committed to finding new ways to make tnis unique product workfor fluid processing industries. As time ana technology create new problems. Union Carbide wi>* continue to provide users of GRAFOIL Flexible G'aphiis with the ultimate contro: in fluid sealing products UCC011875 GRAFOIL For Maximum Sealabiiity Extends Equipment Life ne key to the success of ** GRAFOIL Flexible Graphite 'i\ ($ its ability to create and maintain superior seals under conditions ranging from the ordinary to the most demanding. The effectiveness of `nose seals is a direct result of the inherent qualities o* graphite enhanced by the unique Union Carbide process that transforms It into GRAFOfL Brand Flexible Graphite. An important example of the flexibility of GRAFOIL* fluid sealing rnateriais is seen in the ease with which they conform to challenging spaces while maintaining their superior resilience. Pits, gouges, and even microscopic irregularities arefiliea under only moderate bolt loads to create leak-tight seals reducing the need for costly surface finishing. Gasket creep relaxation -- defined as the continued plastic flow of a sealing materia* with resultant loss of load -- is a common problem with other gasketing materials. Not so with gaskets made of GRAFOIL- Flexible Graphite. While maintaining an effective seal, the GRAFOiL material exhibits virtually no gasket creep relaxation. As a result, the need for periodic bolt tightening is greatly reduced. For dynamic applications such as valve and pump packings, GRAFOIL packings compress to fill available stuffing box space and form leak-free rings. An installed column of GRAFOIL Packing Rings has no open spaces or interstices for leak path development often found in conventional braided packing sets In addition, the integrity of the seal is further enhanced by the inherent resilience of GRAFOfL sealants wh.ch remain unchanged by time, temperature, or a wide variety of industrial chemicals. This special combinat.GP of properties enables GRAFCIL Fiexioie Graphite to create superior seals for applications ranging from precision pipe threads to large valves and flanges. Since GRAFOIL Fiexioie Graphite is made cf natural graphite, it maintains its iubncify in even the most severe applications. The inherent lubncity of graohite is a result of its crystalline structure. Very thin, flat crystals are arranged in a regular pattern and in such a way that they slide easily against each other. This lubricating characteristic enables GRAFOIL Flexible Graphite to preserve vital sealing surfaces. Other sealing materials rely on added lubricants that leach or squeeze cut in service, causing the packings to narden, become brittle, damage the sealing surfaces of pumps, valves, and flanges. GRAFOIL Flexible Graphite has such a low coefficient of friction that it is classified as a solid lubricant. Properly installed, this superior packing product virtually eliminates abrasion or mechanical wear of valve stems and pump shafts. The generation of heat produced by a high-speed centrifugal pump is aiso kept to a minimum, preserving the life of the shaft. Gaskets and packings made from GRAFOIL Flexible Graphite are superior conductors of heat. GRAFOIL packing is up to forty times .more effective in carrying damaging heat away from rotating shafts than other packing materials. This thermal conductivity' is direction-dependent and can be used to conduct frictional and process heat away from the heat source, contributing to increased equipment life GRAFOIL Flexible Graphite aiso protects flange surtaces. Rapid heat transfer to a gasket's outer edge guards against hot spots that typically cause damage. The thermal conductivity of a GRAFOIL gasket is markedly higher than that exhibited by a gasket made of elastomeric bonded materials. In addition, the GRAFOfL material Coes not vulcanize. Residual materia! is easily removed without Damaging flange faces UCC 011876 Reducing Operating Costs Through increased Uptime arly in its development. GRAFOIL Flexible Graphite was considered too costiy for a!! but the most challenging fluid seating problems. That has chanced. The actual cost of GRAFOIL sealing products has been reduced through the use of advanced production techniques. initial price, however is only one factor when determining the value of sealing materials. Because most conventional sealing products have properties that limit their use, they tail prematurely in hostile environments. Asbestos rapidly loses its water cf crystallization as temperature increases. Nearly all braided packings (asbestos, fiberglass, aramias. etc.) lose the added lubricant necessar y to maintain their flexibility. They dry out, harden, and become abrasive, causing damage to a valve stem, pump shaft, or other contacted surfaces. Abrasion or sealed surfaces can be hastened when fluid handling equipment is insulated, preventing heat from escaping anc increasing interior thermal stress. GRAFOIL packings and gaskets have no added lubricants, binders or filler materials to leach out. Therefore seats created with GRAFOIL las: almost indefinitely in virtually any :fj:d sealing application. Because packings and gaskets made with GRAFOIL Flexioie Graphite fit! so many fluid seating needs, the cost of maintaining a large inventory of different, materials is greatly reduced. Additionally, the natural lubricity and resilience of GRAFOIL Flexible Graphite also contribute to cost savings by giving these materials an infinite sheif life. Since graphite is manly resistant to thermal shock, even extreme temperatures do not present a problem to GRAFOIL products. Gaskets and packings remain resilient and flexible in neutral or reducing atmospheres 'angina from -400F to weir over e 3000"F Effect've sealing charac terises are maintained, preventing the less of costly process fluids. These superior seating characteristics result in lurther savings by minimizing the number of giand or fiange adjustments required during the long service life of GRAFOIL gaskets and packings. One Materia! Shaped To Your Fluid Sealing Needs RAFOiL Flexible Graphite can be calendered, corrugated, wrapped, injected or molded into a complete range of shapes and densities to fit virtually any fluid sealing need. Union Carbide engineers have taken advantage of the exceptional fiexibil'ty inherent in this unique product to create an Impressive selection of preformed gasketing and packing oroducts. in addition. GRAFOIL Flexible Grapr.ite is available in a variety of sheet, seif-adhering tapes, and RibbonPack products that may ce customized by Union Carbide, by authorized manufacturing distributors of GRAFOIL fluid sealing products, or even by your own maintenance engineers. This flexibility, combined with the un;que sealing characteristics of GRAFOIL Flexible Graohue, has maoe if the product cf choice- in virtually every industry with fluid sealing needs. In both packing and gasketing appli cations L has become the specified materia', in such cru'eat areas as nuclear steam generation.chemical production, c'yogen cs and petroleum refining. UCC 011877 Enhanced Plant Safety ecent revelations about the health hazat ds of asbestos and the increasing strains placed on gaskets and packings by modem technology have made safety a prime consideration when selecting material. Because of its special charac teristics. GRAFOiL Flexible Graphite has long been considered one of the safest materials tor nearly ail fluid sealing applications. Its proven ability to maintain a tight seal in the harshest environments greatly reduces the chance of exposing workers to toxic or super-heated fluids, in addition, GRAFOIL sealing products have been proven tire-safe in the presence of highly volatile fluids and extremely high temperatures. And, unlike asbestos, GRAFOIL Flexible Graphite poses no inherent threat to Ihe safety of workers. Because it remains stable under exposure to hazardous nuclear radia tion, gaskets and packings made from GRAFOIL Flexible Graphite have been accepted tor use in the primary steam loop of nuclear power plants. Premium (nuciear) grades of GRAFOIL fluid sealants are certified to meet the most demanding specifications in today's nuclear powered steam plants.
