促进剂Rhenogran MTT 80； Vulkacit CRV； SPchem MTT
产品名称：SPgran MTT-80
合成物：80％ 噻唑衍生物＋ 20％ 乙丙橡胶和分散剂载体
同类物：Rhenogran MTT 80
CAS号：1908-87-8
ETU替代品
1.本橡胶促进剂具有的良好物理性能和耐老化性能，是传统促进剂ETU（Na-22）环保型替代品，不产生亚硝胺致癌物质。
2.改进了胶料的焦烧性能和操作安全性，并兼有较快的硫化特征。
3.本品是一种噻唑类杂环化合物，含有活性硫原子，对含卤素的高分子聚合物产生交联，尤其可以作为氯丁橡胶的高效促进剂。
产品应用：
1.有效用于含卤素的高分子聚合物，如氯丁橡胶等。
2.与SPgran HPCA共同使用效果更佳。HPCA 和MTT可作为共交联活性剂、第二促进剂，分别用于或并用于以TCY为主促进剂的硫化体系中，从而替代ETU形成无铅安全硫化体系。
3.SPgran MTT-80可替代ETU用于硫黄调节型CR中；与ETU相比，SPgran MTT-80胶料的加工安全性能好，硫化速度快，胶料物理性能相差不大，且符合环保要求。
4.本品在橡胶中易分散、不污染、不变色，通常用于制造电缆，胶布、胶鞋、轮胎、艳色制品。

ETU Alternative
1.This rubber accelerator can be used as an environmental-friendly substitute for ETU (Na-22) because it generates no N-nitrosamine.
2.It has good physical properties and the anti-aging performance, also improved scorch performance and safety of operation,and has the characteristics of fast curing.
3.This product is a kind of thiazole ring compounds, containing active sulfur atom, cross-linking of polymers containing halogen； especially can be used as efficient promoters of chloroprene rubber.
Application:
1.Especially effective in halogen-containing polymers, such as CR.
2.It is recommended to be used in combination with SPgran HPCA. For ECO, SPgran HPCA-50 and MTT-80 can be separately used or combined in TCY curing system as co-crosslinking active agent or secondary accelerator , which can form a safe non-lead curing system.
3.SPgran MTT-80 can replace ETU in sulfur-regulated
