牌号SPgran HPCA-50 合成物：50％叔胺类活性剂＋50％ 乙丙橡胶载体和特殊分散剂 SPgran HPCA-50是特别为CR、HIIR、ECO, CO、CPE(CM)、CSM、AEM、ACM等含卤素橡胶配方优化的组合硫化活性剂和防老化体系。在氯丁橡胶和含有卤化丁基橡胶料中可取代不容易分散的 MgO，氯丁橡胶硫化胶仍然具有优异的耐热性； 可同时平衡快速硫化和加工安全性。特别是与ZnO、ETU（有毒性）或 MTT（环保无毒性，ETU替代品）并用可以大大改善压缩永久变形。 SPgran HPCA-50可以与TCY并用于硫化氯醇橡胶ECO和CO，可以加快硫化速度，同时改善压缩永久变形。用于NBR/PVC胶料中，同样可以加快硫化速度，同时改善压缩永久变形。 Composition：50％ tertiary amines active agent, 50％ EPDM/EVM binder and dispersing agents SPgran HPCA-50 is specially made for CR, HIIR, ECO, CO、CPE(CM)、CSM、AEM、ACM and other Halogen-containing rubber in curing active agent and anti-aging system. In CR and HIIR-containing rubber, it can replace MgO which is not easily dispersed, and keep rubber with good heat resistance； at the same time balance the fast curing speed and processing safety； Combining with ZnO,ETU(poisoning), or MTT(non-poisoning, replacing ETU) can improve the permanent compression set dramatically. SPgran HPCA-50 together with TCY can be used in ECO/CO, accelerating curing speed, and improving permanent compression set. Likewise, they can be used in NBR/PVC.
