   Buna-N (Nitrile)
 
     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).
 
   Viton®
 
     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® (Dow DuPont Elastomers) perfluorinated elastomer, they are about the most highly temperature resistant of all commercially available elastomers. Viton® is a registered trademark of DuPont Dow Elastomers.
 
   Ethylene Propylene (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® (Exxon Mobil Chemical), Epsyn® (DSM Elastomers), Royalene® (Uniroyal Chemical), and Epcar® (B.F. Goodrich).
 
   Polyurethane
 
     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).
 
   Silicone
 
     Silicones are polymers in which organics groups, such as methyl and phenyl groups are bonded to the silicone atoms in chains of inorganic siloxanes (-Si-O-Si-). Their properties include heat, cold and weather resistance, electrical insulation, release, water repellency and defoaming.
 
   Other
 
     Other unlisted or proprietary material.
