Stabilizers / PVI

Characteristics

PVI functions as a pre-vulcanization inhibitor and anti-scorching agent for both natural and synthetic rubbers. This product provides predictable scorch control in most sulphur vulcanization. PVI provides improved cost performance through marginal stock recovery, single-stage mixing and higher processing and/or curing temperatures.
