Alkylphenol Disulfide Curing Agent

We are offering alkylphenol disulfide curing agent ( of-710) description alkylphenol disulfide (apds) curing agent contains the active sulfur which can vulcanize rubber at heating, no blooming, providing the compound with high tensile strength and excellent heat-resistance. Application of-710 is a new type of nitrosamine-free sulfur donor, replacing partly or completely sulfur and dtdm in efficientsemi-efficient vulcanizing systems. It is used mainly in the tire rubber of innerlinner, the sidewall and the tread, also used for gasket, conveyor belts, car hoses, shock absorption products etc. Because of the alkyl phenol groups contained, of-710 has the viscous and antioxidant effect. Especially in curing the compound of nr, ciir, briir, iir and epdm, it makes co-vulcanization, provides high tensile strength, excellent reversion, oxidation and heat aging resistance while giving no nitrosamines toxic gas and non staining.   the referenced dosage is 0.5~5 phr.
