Description: NV 7030 is a blend of nitrile rubber and PVC. After adding vulcanizing agent, the compound is vulcanized and formed (the vulcanizing agent is selected according to the process requirements).
Special properties:
Calendering and pressing out are fast and the surface is smooth
Good storage stability
Excellent abrasion & tear resistance
Ozone resistance & excellent weather resistance
Excellent oil and solvent resistance
Excellent antistatic property
Excellent flame retardancy
