Description
This Accelerator ETU(NA-22) is chloroprene rubber CH and W type and chloroethanol rubber, polyacrylate rubber products for the special accelerator. It is also used in fine chemicals intermediates, antioxidants, insecticides, dyes and synthetic resins for wire, cable, rubber, pipe belt, rubber shoes, rain boots and raincoats.
Function
JXBHgran ETU-75 can accelerate the rapid curing of chloroprene rubber, and has good anti-scorch performance. In other diene-based rubbers, vulcanization systems containing sulfur or a small amount of sulfur can be used as active agents and auxiliary accelerator. Using JXBHgran ETU-75 accelerator, excellent anti-aging performance and mechanical properties can be obtained.
