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 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。

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.
