NBR PVC Rubber Plastic Blends
NBR PVC Rubber Plastic Blends
NBR PVC Rubber Plastic Blends
NV rubber and plastic blend is a blend of nitrile rubber and PVC. The rubber compound is vulcanized and molded after the vulcanizing agent is added (the vulcanizing agent is selected according to the process requirements).
product details
Applications: NV rubber and plastic blend rubber has excellent properties such as oil resistance, high strength and high hardness, so it is suitable for manufacturing oil pipes, rubber pipes, wires and cables, sheaths, belts, soles, rollers and other products.
Special properties:
- Rapid calendering and extrusion and smooth surface
- The storage stability is good
- Excellent wear and tear resistance
- Excellent ozone & weather resistance
- Excellent grease and solvent resistance
- Excellent antistatic property
- Good low temperature resistance
- excellent in flame retardancy
