NBR rubber gasket
NBR (Nitrile) rubber has good resistance to petroleum oils, aromatic hydrocarbons, mineral oils, vegetable oils, and many acids. It also has good elongation properties as well as adequate resilience, tensile and compression set.
Neoprene rubber gasket
Neoprene (CR) rubber is one of the best all-purpose rubber where resistance to ozone, sunlight, oxidation and many petroleum derivatives are of prime importance. Added advantages include good resistance to water, chemicals, flame, abrasion, flex cracking etc. It also has good resilience characteristics and tensile strength.
EPDM
rubber gasket
EPDM rubber is ideal for outdoor applications because of its excellent
resistance to heat, ozone, oxidants, UV rays, and severe weather conditions. It
shows good resistance to many corrosive chemicals however does not have good
oil resistance.
FKM rubber
gasket
FKM (Viton) rubber has excellent resistance to oil, flame, chemical corrosion,
weathering and aging. It resists a wide variety of corrosive fluids at elevated
temperatures while retaining their mechanical properties. The material is also
with good tensile strength, resilience, and low compression set.
