    应用:这类促进剂的促进效力低且抗烧焦性能差,故对二烯类橡胶已很少使用,但在特殊情况下,如用秋兰姆硫化物等硫黄给予体硫化时,本品具有活性剂的作用,硫脲类促进剂对氯丁胶的硫化却独特的效能,可制得抗张强度、硬度、压缩永久变形等性能良好的氯丁硫化胶。本品与NA-22相比,焦烧及硫化均快,但硫化平坦性较好。易分散、不喷霜。用量较大时,可进行高温高速硫化,特别适用于压出制品的连续硫化,本品也是丁基胶用促进剂,三元乙丙胶的硫化活性剂。对于天然胶、氯丁胶、丁腈胶和丁苯胶有抗氧化作用。一般用作制造工业制品、特种电线、海绵制品等。

    Application: These enhancers to promote the effectiveness of anti-burning properties of low and poor, so for the second vinyl rubber has been rarely used, but in exceptional circumstances, such as thiuram sulfides with sulfur donor vulcanizing, etc., the goods with the activity the role of agent, thiourea type accelerator of vulcanization of the neoprene is a unique performance, can be obtained tensile strength, hardness, compression permanent deformation, such as good performance neoprene vulcanizate. This product with the NA-22 compared to scorch and curing are faster, but better flat vulcanization. Easily dispersed, do not emit cream. Larger amount, they can carry out high-temperature high-speed vulcanization, is particularly applicable to the products of continuous pressure vulcanization, the goods-butyl rubber is also used to promote the agent, EPDM rubber vulcanization agent must live. For natural rubber, neoprene, nitrile rubber and SBR have antioxidant. Generally used for manufacturing industrial products. Special wires, sponge products.
