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 goodCharacteristics: Product
