You can select from a broad choice of materials that will provide the compound best suited to your product application. Some examples are:

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 and electricity – used 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 temperature range of -150 F to 550 F.
VITON	Will withstand extreme temperatures and is fuel and oil resistant.
