Material Many seal manufacturers use their own proprietary material. Where possible, these materials have been categorized into the generic equivalent or material family. Consult with manufacturer for proprietary material specifications.
   Material      A polymer is a solid, nonmetallic compound of high molecular weight the structure of which is composed of small repeat units (mers). Plastics and elastomers are polymers.
   Your choices are...         
   Ethylene Acrylic (AEM - Vamac®, etc.)       Ethylene acrylic compounds provide high-heat aging resistance while providing good physical properties. They offer a high degree of oil, ozone, UV, and weather resistance along with good low temperature flexibility. Suggested operating temperature (-20° to 300° F). Manufactured under the trade name Vamac® by DuPont Dow Elastomers. 
   EPDM       Good resistance to sunlight, weathering and ozone. It has poor resistance to petroleum oils and fuel. Good heat and compression set resistance. Suggested operating temperature (-70° to 275° F). Trade names include Nordel® (DuPont Dow Elastomers), Vistalon® (ExxonMobil Chemical), Epsyn® (DSM Elastomers), Royalene® (Uniroyal Chemical), and Epcar® (B.F. Goodrich). 
   Fluoroelastomer (FKM - Viton®, Fluorel®, etc.)       A range of fluoropolymer elastomers whose formulation can be tailored to a reasonable extent to meet the needs of individual end-uses. They are normally black and have high heat, oil and chemical resistance but indifferent low temperature performance. With the exception of Kalrez® perfluorinated elastomer, they are about the most highly temperature resistant of all commercially available elastomers. Trade names include Viton® (DuPont Dow Elastomers), Fluorel® & AflasTM (3M Corporation), and Technoflon® (Montedison). 
   Flourosilicone (FVMQ, FMQ, FPM, FSI)       The mechanical and physical properties are very similar to silicone. However, Flourosilicone offers improved fuel and mineral oil resistance but poor hot-air resistance in comparison. Suggested operating temperature (-100° to 350° F). Trade names include FSE® (General Electric Co.), Silastic® (Dow Chemical), and Sylon® (3M Corporation). 
   Nitrile (NBR - Buna-N)       Good resistance to petroleum hydrocarbons and fuels. Widely used with most oils, hydraulic fluids, and alcohol. Many compound variations are available for specific applications. Suggested operating temperature (-30° to 275° F). Trade names include Breon® (BP Chemicals), Chemigum® (Goodyear), Hycar® (B F Goodrich), Krynac® (Polysar Ltd.), Nipol® (Zeon Chemicals), Nysyn® NBR, (DSM Elastomers), Paracril® (Uniroyal Chemical), and Perbunan® (Mobay). 
   Nitrile - Highly Saturated (HNBR)       Nitrile has good mechanical properties when compared with other elastomers and high wear resistance. Nitrile is not resistant to weathering and ozone. Suggested operating temperatures from (-40° to 300° F). Trade names include Therban® (Mobay), Tornac® (Polysar), and Zetpol® (Nippon Zeon Company). 
   Nylon / Polyamide       Nylon, comprising several grades of polyamides, is a general-purpose material in wide use; it is tough and resistant and has good pressure ratings. 
   Polyacrylate (ACM)       Polyacrylate elastomers are well suited for use with extreme pressure (EP) lubricants and have high resistance to oxidation and ozone. Polyacrylates are not recommended for dry running applications. Suggested operating temperature (-25° to 350° F). Trade Names Include Cyanacryl® (American Cyanamid), HyTemp® (BF Goodrich), and Thiacril® (Uniroyal). 
   Polychloroprene (CR - Neoprene)       A synthetic rubber that resists degradation from sun, ozone, and weather. It performs well in contact with oils and many chemicals. Neoprene remains useful over a wide temperature range, displays outstanding physical toughness, and resists burning inherently better than exclusively hydrocarbon rubbers. Neoprene also offers resistance to damage caused by flexing and twisting. Suggested operating temperature (-45° to 230° F). Trade names include Neoprene (DuPont Dow), Baypren® (Mobay), and Butachlor® (Ditsugil). 
   Polyetheretherketone (PEEK)       PEEK is a high temperature resistant engineered thermoplastic. It has excellent chemical and fatigue resistance, and thermal stability. PEEK has superior chemical resistance, is inert to all common solvents and resists a wide range of organic and inorganic liquids. PEEK has a maximum continuous working temperature of 480°F and retains its mechanical properties up to 570°F in steam or high-pressure applications. 
   Polyoxymethylene (POM, Acetal)       Acetal polymers are semi-crystalline. They offer excellent inherent lubricity, fatigue resistance, and chemical resistance. Acetals suffer from outgassing problems at elevated temperatures, and are brittle at low temperatures. Glass filled, and added lubrication grades are available, flame-retardant grades are not. Brand names include: Celcon (Hoechst Celanese), Delrin (DuPont), Thermocomp (LNP), Ultraform (BASF). 
   Polytetrafluoroethylene (PTFE- Teflon®, etc.)       PTFE is an insoluble compound that exhibits a high degree of chemical resistance and a low coefficient of friction. It is sometimes marketed in proprietary classes of materials such as Teflon®, a registered trademark of DuPont Dow Elastomers. 
   Polyurethane / Urethane       Polyurethane is a diverse class of materials exhibiting good elongation, recovery and toughness properties. They are flexible and have good abrasion resistance. (NOTE: The urethanes of the plastics industry are so named because the repeating units of their structures resemble the chemical urethane.) Trade names include Texin® (Bayer), Adiprene® and Vibrathane® (Uniroyal Chemical), Estane® (B F Goodrich), Genthane® (General Tire and Rubber), Millathane®, and Pellethane® (Dow Chemical). 
   Rubber - Natural (NR)       Natural compounds such as gum rubber (polyisoprene) and latex.
