N-(cyclohexylthio)phthalimide (CTP) is a pre-vulcanization inhibitor (PVI) and scorch retarder widely used in rubber compounding to extend the processing safety period without adversely affecting vulcanization rate or crosslink density. It is the industry standard pre-vulcanization inhibitor for sulfur-cured rubber systems. SUNCHEM supports international buyers with N-(cyclhexy thio) phthalimid sourcing from qualified Chinese producers, with quality documentation, export coordination, and logistics support.
