Material introduction:
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
