Mixture of poly-tert-butylphenoldisulfide and stearic acid CAS NO.60303-68

Chemical Name: Mixture of poly-tert-butylphenoldisulfide and stearic acid
CAS No.:60303-68-6 ; 57-11-4
Molecular structure

Appearance: Light yellow to brown granules
Sulfur content,%:26.4-28.4
Softening Point,℃:75-95
Stearic acid, %: 9.0-11.0

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. It forms 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.

It contains active sulfur and can vulcanize rubber under heating condition. The
vulcanizate has the properties of non-frosting, high tensile strength and
excellent heat resistance. It can be used as sulfur donor vulcanizing agent for
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, it partially or completely
substitutes sulfur, DTDM and other sulfur donors. It does not produce nitrosamine
toxic gases in the vulcanization process. It is environmentally friendly additive.

It is used for tyres’ inner layer, sidewall, tread, bead filler, sealing gasket,
conveyor belt, automobile rubber hose, shock absorption and so on.
