Nitrile rubber (NBR, Buna-N) provides excellent resistance to petroleum oils as well as mineral and vegetable oil. Nitrile rubber also offers strong resistance to heat aging - often a key advantage over natural rubber.
Nitrile rubber performs well in carburetor and fuel pump diaphragms, aircraft hoses, seals and gaskets as well as oil-lined tubing. Due to its versatility, nitrile is used in applications involving not only oil and fuel resistance, but those applications requiring resistance to heat, abrasion, water, and gas permeability.
EPDM rubber is a high density rubber primarily used for outdoor applications. It has dynamic and mechanical properties between natural rubber and synthetic rubber.
Do not use EPDM if continual contact with petroleum based products is required.
Not recommended for usage in food applications or those that are exposed to aromatic hydrocarbons.
Application:
1. Semi-conductor process tools and fixture
2. Mechanical seals
3. High strength kiln furniture
4. Various wear parts
5. Various corrosion resistant parts
6. Oxidation resistant crucibles
7. Protection and safety
8. Water pump seals
