Nitrile Butadiene Rubber

Nitriflex NBR

Nitriflex NBR is an acrylonitrile butadiene copolymer which is polymerized (hot or cold) with a non-staining antioxidant.


Nitriflex NBR is recommended for applications that require excellent resistance to oils and fuels.

Nitrile (NBR) Clean

NITRIFLEX NBR CLEAN is a cold polymerized acrylonitrile-butadiene copolymer line that has a varying content of acrylonitrile and Mooney viscosity across many different grades.


The ‘CLEAN’ line is designed for high performance injection molding applications because it has very low mold fouling. Other properties that distinguish this grade are: heat stability, high flow, and faster cure rates enabling maximum productivity in all molding processes. This is especially true for injection molding of rubber goods.

Nitriflex’s carboxylate grade(s) also improves abrasion resistance, strength and traction.
