应用：本品系氯丁胶用快速硫化促进剂,性能与ETU和DETU相近,适用于硫化温度较低的胶料,制品物理性能较好。对天然胶、丁苯胶、丁基胶、三元乙丙胶的硫化亦有促进作用。也是天然胶、氯丁胶、丁腈胶和丁苯胶的抗臭氧剂。不污染,不变色。主要用于电线、工业制品和海绵制品等。
Application: DBTU is an ullra-accelerator for mercaptan-modified CR(1-3phr). It has a vulcanizalion behaviour similar to that of ETU and DETU. It is also used as a second accelerator for NR and synthetic rubbers. It disperses easily in rubber. It is non-staining and does not bloom. It is practically odourless Antioxidant for NR, antiozonant for NR and SR, particularly SBR. It is also a corrosion inhibitor.
