Powder NBR(Special for friction material)
1、Improve heat resistance, oil resistance, wear resistance and low temperature resistance.
2、It has good dispersibility in raw material blending and reduces product friction rate.
3、In the process of use, reduce the hardness of the product, improve the braking noise of the product, improve the comfort of the braking process.
4、The fluidity and brittleness of phenolic resin were improved obviously. The combination of phenolic resin and phenolic resin had a good complementary effect and improved the stability of friction coefficient. It can obviously improve the cracking and edge breaking of drilling.
Good low temperature resistance to flexure, compression permanent deformation, aging resistance, improve the impact resistance of the product.
