Good Adhesion Propeties Nitrile Butadiene Rubber Foam Self Adhesive
Nitrile closed cell sponge NBR rubber is an excellent gasket
material for sealing applications that require oil and UV
resistance.
Also resistant to vegetable oil, animal oil, and mineral oil,
gasoline, diesel and other aliphatic and aromatic hydrocarbons.
Closed Cell oil resistant Nitrile Sponge Rubber can handle
temperatures ranging from -40°C to +95°C.
Sponge NBR rubber is an excellent material for gasket applications
that require a soft compressible material.
Closed Cell Nitrile Rubber is a sponge formulation that is
manufactured with a continuous skin on both sides. The skin makes
the sponge stronger and more tear resistant.
Even if the skin is punctured or cut, the sheets will not allow
passage of air or fluid between cells. These gaskets are highly
compressible, resilient, light weight and provide good thermal
insulation.
