Powder nitrile rubber for friction materials
Category：
Description
● Product characteristics
HLN40 series powdered nitrile butadiene rubber is developed for modifying phenolic resin and other polymer materials, and has excellent compatibility with phenolic resin. With good bonding effect, it can increase the bonding ability of friction material system, improve the impact resistance of friction products, stabilize friction and wear, and reduce noise.

● Application advantage
1. Reduce the elastic modulus of the matrix, improve the fit with the friction pair, and obtain a high and stable friction coefficient.
2, in the rigid resin matrix, mixed with powder nitrile rubber particles, because the composite matrix is filled with soft particles of elastomer, reduce the wear of the product.
3, powder nitrile rubber as an elastomer, has a good toughening effect, improve the impact resistance of products.
4, reduce the hardness of the product, can reduce the braking noise.
● Application field
Brake pads, composite brake shoes, conveyor belts, etc.
