| Vulcanizing Agent (Alkylphenol disulfide polymer sulfur donor) |
 |
Sulfur donor for natural and synthetic rubbers. We produce a high percentage of mono-sulfidic crosslinks that results in vulcanizates with superior aging characteristics. It 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 it is used in the innerliner, chafer, bead apex, sidewalls, and tread. Industrial applications include noise damping blocks, motor mounts, dock fenders, elastic threads, automobile engine hoses, gaskets, belts, and other industrial rubber products that require good heat resistance. It also aids in rubber processing.
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. It tends to improve dispersion of other additives in the rubber.
Crosslink Type: It promotes mono-sulfidic crosslinks resulting in vulcanizates with excellent heat and aging resistance.
Non-nitrosamine: It does not produce nitrosamines like many of the other sulfur donors such as DTDM and the thiurams. |
