用途
Apoplications
橡胶工业中用作超硫化促进剂，常与噻唑类促进剂并用，也可与其它促进剂并用作为连续胶料的促进剂。因在100℃以上即缓缓分解折出游离硫，故可作硫化剂。制品的老化性和耐热性极 好。适用于天 然胶、合成胶。主要用于制造轮胎、内胎、胶鞋、电缆等工业制品。农业上用作杀菌剂和杀虫剂，也可用作润滑油添加剂。Can be used as a super vulcanization accelerator in Rubber industry, often with thiazole accelerators, can also be used with other accelerators as a continuous rubber accelerator, Because it slowly decomposes free sulfur above 100*C, it can be used as vulcanizing agent. The product has excellent aging resistance and heat resistance. It is suitable for natural glue and synthetic glue, Mainly used in manufacturing tires, inner tubes, rubber shoes, cables and other industrial products. In agriculture, it is used as a fungicide and insecticide, and also as a lubricant additive.
