Product Description

                                                                NBR 3305E

 

Nitrile butadiene rubber.

 

Nitrile butadiene rubber (NBR), is made of acrylonitrile and butadiene monomer polymerization copolymer, mainly using low

temperature emulsion polymerization production, excellent oil resistance, high wear resistance, good heat resistance, strong
adhesion.

Nitrile butadiene rubber is mainly used in the manufacture of oil resistant rubber products
