Powder Nitrile Rubber for Friction Materials
PNBR for Friction Materials Application
Product Characteristics
The HLN40 series of powder nitrile rubber is developed as a modifier for phenolic resins and other polymer materials, exhibiting excellent compatibility with phenolic resins. It provides good bonding properties, enhances the adhesive strength of friction material systems, improves the impact resistance of friction products, stabilizes friction and wear, and reduces noise.
| Grade | Mooney Viscosity | Bound Acrylonitrile % | Crosslinking Type | Particle Size |
|---|---|---|---|---|
| HLN40-1 | 100～150 | 36～40 | Fully Crosslinked | <0.45mm |
| HLN40-2 | 60～100 | 36～40 | Fully Crosslinked | <0.45mm |
| HLN40-3 | 150～200 | 36～40 | Fully Crosslinked | <0.45mm |
| HLN40-4 | 130～170 | 30～35 | Fully Crosslinked | <0.45mm |
Application Advantages
- Reduces the elastic modulus of the matrix, improves compatibility with friction counterparts, and achieves a higher and more stable friction coefficient.
- Incorporating powder nitrile rubber particles into rigid resin matrices creates soft points throughout the composite matrix, reducing product wear.
- As an elastomer, powder nitrile rubber provides excellent toughening effects, enhancing the impact resistance of products.
- Reduces product hardness, thereby lowering brake noise.
Application Fields
Brake pads, train composite brake blocks, conveyor belts, etc.
