What is PVI used for in rubber compounds?

PVI is used as an ideal pre vulcanization (scorch) inhibitor for NR, IR, NR-BR blend, SBR, NR-SBR, SBR-BR blends, NBR, CR and other diene rubber based accelerated sulphur cured compounds.

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.

Is PVI used as a scorch inhibitor?

PVI is an ideal pre-vulcanization (scorch) inhibitor for various types of rubber compounds, including NR, IR, NR-BR blend, SBR, NR-SBR, SBR-BR blends, NBR, CR, and other diene rubber based accelerated sulphur cured compounds. PVI is effective as a scorch inhibitor with almost all types of accelerators.

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.

How long does pentotard – PVI last?

Up to 1 year in normal storage conditions. Consult material safety data sheet (MSDS) for additional handling information for Pentotard – PVI. Information provided herein is based upon tests believed to be reliable. We have no control over the manner in which others may use this information, it does not guarantee the results to be obtained.

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.
