NB(NBR)
Description
This material is based on nitrile rubber (NBR). It is a product designed for the production of rubber products. It is widely used in some rubber products factories. It has high strength, high hardness, heat resistance, oil resistance, solvent resistance and acid resistance. Alkali, low compression set, good process performance.
Use
It can be used to manufacture rubber and oil resistant products for petroleum, chemical, automotive and other industries.
