Introduction
PNBR 35-2 is a micro-crosslinked powdered nitrile rubber known for its excellent compatibility with PVC. It functions as a primary elastomeric modifier in PVC formulations, enhancing oil resistance, thermal stability, and low-temperature flexibility.
In wire and cable applications, PNBR 35-2 provides internal plasticizing effects, resulting in softer, more elastic products with improved aging and fatigue resistance.
Note: Finished products may retain a distinct rubber odor.
Country of Origin: China
Physical Properties
| Appearance | White or slightly yellow powder |

Applications
PNBR 35-2 is widely used in the production of:
- Footwear components
- Oil-resistant hoses
- Wire and cable insulation
- Sealing strips
- PVC pipes
- Foamed materials
Typical dosage: 5–30 phr
Processing note: For optimal dispersion, PNBR 35-2 should be added during the cooling phase to prevent powder agglomeration.
Recommended for: Applications requiring anti-slip performance.
