Alkylphenol disulfide polymer sulfur donor

Arkema Vultac TB7 equivalent CAS NO.:60303-68-6

Rubber Vulcanizing agents: VA-TB7
Nitrosamine-free vulcanizing agent; ultra-fast curing speed;
Product Name	Poly-tert-butylphenol disulfide; 4-(1,1-Dimethylethyl)phenol polymer with sulfur chloride Tert-butylphenoldisulfide polymer
CAS Number	60303-68-6
Specification	Criterion	Requirement
	Appearance	yellow to light brown pastilles or powder
	Sulfur content, % (test way:Combustion)	29.5-31.5
	Softening point (℃) (test way:Ring & Ball)	95-115
Applications	Uses: Sulfur donor for natural and synthetic rubbers. VA-TB7 produces a high percentage of mono-sulfidic crosslinks that results in vulcanizates with superior aging characteristics. VA-TB7 can be used as either complete or partial replacements for sulfur and thiuram and DTDM sulfur donors in EV and semi-EV type cure systems. In tires VA serials are used in the innerliner, chafer, bead apex, sidewalls, and tread. bleaching agent in the disproportionation of rosin or rosin esters. Polymers: Natural rubber and synthetic elastomers. Especially good in curing rubber that contains chlorine such as chlorobutyl and polychloroprene. Synergism: Can be used with most typical rubber accelerators and sulfur. When used as a partial replacement for sulfur, VA-TB7 tends to improve dispersion of other additives in the rubber. Crosslink Type: VA-TB7 promotes mono-sulfidic crosslinks resulting in vulcanizates with excellent heat and aging resistance. Non-nitrosamine: VA-TB7 does not produce nitrosamines like many of the other sulfur donors such as DTDM and the thiurams.
