性状: 淡黄色颗粒，无毒，微有氨味，熔点78 ℃ 以上，比重1.34-1.40 ，溶于苯、丙酮、氯仿，不溶于水，稀酸稀碱，受热60℃ 以上逐渐分解。
Properties: Light-yellow granule. No poison with a little odor of ammonia,The density is 1.34-1.40.
Soluble in benzene、acetone、chloroform, insoluble in water and acid, alkali with lower concentration.
用途: 为后效性硫化促进剂，活性小，退延性较大，硫化时间短，抗焦烧性能优良，加工安全，易分解，不喷霜，轻微变色，适用于天然胶和合成胶，主要用于制造轮胎、胶管、胶鞋、运输带等工业橡胶制品。
Usage: An excellent delayed accelerator. The performance is similar as willing CZ with better scorch safety. Widely used in NR、IR、SBR、NBR.and EPDM. Can be used alone or with other vulcanization accelerators such as thiurams,guanidines and dithiocarbamates to improve the activity. Mainly used in manufacture of tires, shoes and belts.
