TB710 acts as a nitrosamine-free vulcanizing agent.It also acts as an antioxidant because of its phenolic structure. Serves as an alternative for TB7 in cases where an agent of lower softening point is required for good dispersion into a rubber compound.It offers high elastomer solubility.Itforms monosulphide bridges which are more stable and have very good resistance to heat and ageing when compared with typical polysulfide bridges.It is used for polymers like rubber and in tire industry applications.

Itcontains active sulfur and can vulcanize rubber under heating condition. The vulcanizate hasthe properties ofnon-frosting, high tensile strength and excellent heat resistance. It can be used as sulfur donor vulcanizing agentfor natural rubber or synthetic rubber.

It has a good tackifying effect between different polar rubber such as NR, CR, IIR, EPDM and obtains co-vulcanization effect.

In semi-effective and effective vulcanization system,itpartially or completelysubstitutes sulfur, DTDM and other sulfur donors.Itdoes not produce nitrosamine toxic gases in the vulcanization process. Itis environmentally friendly additive.

It isusedfortyres’ inner layer, sidewall,tread,bead filler, sealinggasket, conveyor belt, automobile rubber hose, shock absorption and so on. info at hhochem. com
