PVI – Pre-Vulcanization Inhibitor (N-Cyclohexylthiophthalimide)

Scorch Retarder for Safer Rubber Processing

PVI is a critical additive in rubber compounding used to delay premature vulcanization (scorch) during mixing, extrusion, and storage. It enables better processing control and reduces the risk of early curing before molding.

Improves Safety, Stability, and Product Quality

Widely used in tires, conveyor belts, and molded goods, PVI enhances scorch safety and consistency. It is compatible with a wide range of rubbers including NR, SBR, and BR, and improves shelf life of uncured compounds.

Hamiico supplies high-purity PVI in 25 kg sealed bags, ready for use in industrial rubber compounding operations requiring precision and stability.
