Main purpose
Mainly used for ABS resin, styrene butadiene rubber (SBR), nitrile rubber (NBR), high impact polystyrene (M-HIPS) products, and as a molecular weight regulator in the polymerization reaction process. It can also be used as a stabilizer and antioxidant for polyolefins such as polyvinyl chloride and polyethylene, and as a raw material for the synthesis of certain drugs, insecticides, fungicides, and fragrances.
Tertiary dodecanethiol (TDDM) is mainly used as a molecular weight regulator in the production of ABS and SBR. At present, the domestic ABS production capacity is 1 million tons per year, SBR production capacity is 500000 tons per year, and TDDM demand is 5000 tons per year. Almost entirely dependent on imports, with high prices.
