NBR sponge
Optimal oil-resistant rubber for industrial products
NBR is a copolymer consisting of acrylic-nitrile rubber and butadiene with superior oil resistance and wear resistance, used for oil-resistant applications such as packing for oil-resistant materials, oil seals and packing for hydraulic cylinders.
■ Main applications ： O-ring, seal material, engineering packing material, gaskets, etc.
