EPDM rubber products processing: rubber mixing and vulcanization

EPDM rubber is widely used in automobile industry, electronic and electrical industry, rubber belt, sponge products and tire industry, with excellent elasticity, mechanical properties, electrical properties, heat resistance, weather resistance, ozone resistance and chemical resistance, there are great differences in the formula and process for different types of EPDM rubber products, but the basic process points for EPDM rubber products can not be bypassed.

Key Points of rubber mixing

The EPDM rubber is a classification of the Ethylene propylene rubber, and its processing properties are similar to those of ethylene propylene diene rubber, and its processing properties are good, with the development of the production technology of recycled rubber, many EPDM rubber products have started to use EPDM recycled rubber, among which the excellent EPDM recycled rubber has better fluidity and plasticity than the original when used together with EPDM rubber recycled rubber, it is best to mold the EPDM rubber for a while before adding reclaimed rubber.

Key points of vulcanization

The vulcanization performance of epdm rubber is better than that of epdm rubber (epdm rubber can only be vulcanized by peroxide) , you can also try peroxide, resin curing cross-linking; one of the Acidic Mixture (such as tank black) affect the peroxide curing process, must be used with caution.
