high efficiency rubber accelerator etu thiourea in myanmar
Ethylenethiourea - an overview | ScienceDirect Topics
This rubber is vulcanized with metal oxides, either with or without sulfur; usually a combination of zinc and magnesium oxides, with white lead oxide (litharge or red lead). Lead oxide gives good results where low water absorption is an important requirement. The sulfur modified grades require no additional accelerator for vulcanization.

Ethylenethiourea - an overview | ScienceDirect Topics
Diethylthiourea (DETU) shows similar activity but with somewhat less scorch safety. Other thiourea derivatives are less effective, particularly in respect to attaining low compression set. Concentration effects of ETU in a neoprene W compound with a 60 phr blend of low and medium surface area silicas and magnesia at 2 phr are noted in Table 6.3.
