• NEOPRENE: All purpose outdoor-indoor synthetic rubber resistant to most chemicals, oils, weathers, etc.
• EPDM: Outdoor weather resistant even under extremely severe conditions - resistant to color fade-heat-electricity.
• NITRILE (Buna-N): Especially resistant to aromatic hydrocarbons, gasoline, petroleum oils, mineral and vegetable oils.
• SBR (Buna-S): Non oil resistant, economically priced synthetic rubber - especially noted for its low water absorption properties .
• NATURAL: Extremely
resilient with high tensile & elongation properties - also
resistant to flexing, permanent set & electricity - also used as
seals in food and beverage applications.
• URETHANE: Outstanding tensile and abrasion qualities - excellent resistance to wear, ozone, oxygen, kerosene & gasoline.
• SILICONES: Can withstand extreme heat or cold and retain flexibility - normal temp. range of -150°F to 550°F
• VITON: In addition to its ability ti with-stand extreme temperatures it is also fuel and oil resistant.
