Soluble in benzene, toluene, chloroform, carbon disulfide, dichloromethane, , acetone, ethyl acetate; insoluble in water, gasoline, diluted acids/bases 用 途: CZ是一种高度活泼的后效促进剂,抗焦烧性能优良,加工安全,硫化时间短。在硫化温度138°C以上时促进作用很强。常与TMTD 或其他碱性促进剂配合作第二促进剂。碱性促进剂如秋兰姆类和二硫化氨基甲酸盐类可增强其活性。主要用于制造轮胎、胶管、胶鞋、电缆等工业橡胶制品。 Uses :As a delayed-action accelerator, CZ is the most common sulfenamide accelerator in EDPM based prodcuts such as hose and cable. It is a primarily amine-based accelerator providing medium-fast cure with good scorch safety and excellent modulus development.It is also used as a secondary accelerators in combination with such as TMTD to adjust curing characteristics. 包 装: 25kg/袋 保质期: 12个月 Package 25kg/bag Shelf:24 months
