What is pentotard – PVI?

Pentotard – PVI offers linear and predictable response and is most sensitive to sulphenamide accelerated stocks and highly unsaturated rubbers. Pentotard – PVI can be used effectively in compounds based on NBR/PVC blends, polyacrylic rubbers and sulphur cured polyurethanes.

How can PVI prevent vulcanization in glue processing?

PVI can prevent early vulcanizing in glue processing, Improving safety. At the same time significantly improve the storage stability of the glue, preventing natural vulcanization phenomena. In NS, M, DM, CBS, semi-effective or efficient systems, to improve the plastic materials capability. No foam, pollution and other adverse effects.

Does pentotard – PVI cause contact or migration staining?

Pentotard – PVI does not cause contact or migration staining but can slightly discolor bright white rubber products. Pentotard – PVI can permit addition of curatives at an early stage of mixing for better dispersion of curatives, reduced mixing cycle time, reduced power consumption, reduced labor and capital investment costs.

Does pentotard – PVI affect vulcanizate properties?

Pentotard – PVI does not cause any detrimental effect on the vulcanizate properties such as tensile strength, modulus values, and resilience / heat build up, compression set or permanent set, ozone resistance and hot air aged vulcanizate properties when used at optimum dosage.
