Description: NV series is a blend of nitrile rubber and PVC. The rubber compound is vulcanized with the vulcanizing agent is added (the vulcanizing agent is selected according to the process requirements).

Applications: NV rubber and plastic blend rubber has excellent properties such as oil resistance, Ozone resistance & excellent weather 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:
Excellent abrasion & tear resistance
Excellent ozone & weather resistance
Excellent grease and solvent resistance
Excellent antistatic property
Good low temperature resistance
Excellent in flame retardancy
Rapid calendering and extrusion and smooth surface
The storage stability is good
