Chemical Name: Mixture of poly-tert-butylphenoldisulfide and stearic acid CAS No.:60303-68-6 ; 57-11-4 Appearance: Light yellow to brown granules Sulfur content,%:26.4-28.4 Softening Point,degree: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.
