    应用: 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℃以上即缓缓分解出游离硫,故可作硫化剂。制品的耐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。

    Application: It can be used as a single accelerator, as a secondary accelerator or as a sulphur donor in most sulphur-cured elastomers. Scorchy and gives fast cure rates. Produces an excellent vulcanisation plateau with good heat aging and compression set resistance in sulphurless and EV cure systems Good color retention is obtained in non-black vulcanisation. A valuable secondary accelerator for EPDM. May be used as a retarder in the vulcanisation of polychloroprene rubber and also be used as bactericide and pesticide.
