Composition: 80% 3-methyl-thiazolidine-thione-2, 20% EPDM/EVM binder and dispersing agents • Synonym: Rhenogran MTT 80 • CAS NO.: 1908-87-8 • ETU Alternative 1. This rubber accelerator can be used as an environmental-friendly substitute for ETU (Na-22) because it generates no N-nitrosamine.
Compression set 100 °C/22 h (%) 20 Rubber Curing Systems Most accelerators used in the sulfur vulcanisation of other high diene rubbers are not applicable to the metal oxide vulcanisation of CR. An exception is the use of a so-called mixed curing system for CR, in which metal oxide and accelerated sulfur vulcanisation are combined.
