First, why is the pre-dispersion of rubber auxiliaries a development trend?

Rubber additives are chemicals that bring high added value to rubber products and can reduce costs. However, the traditional rubber additives not only produce a large amount of dust and toxic and harmful gases when used, which brings great harm to the environment and the health of the operator, but also the poor compatibility with rubber, difficult to disperse evenly, affecting its use effect.

Second, rubber additives pre-dispersion definition

Rubber auxiliary pre-dispersion, also known as rubber auxiliary mother pellets. The pre-dispersed rubber additive is based on the polymer (generally EPDM, SBR, NBR, EVA) as the carrier, plus rubber additives and softeners, and the traditional rubber additives are pre-dispersed into the polymer through a special process to obtain a certain concentration of uniform pre-dispersed body (extrusion granization). The pre-dispersed rubber auxiliary is the upgrade of the traditional rubber auxiliary substitute, with no dust, easy dispersion, suitable for automatic weighing and automatic continuous low temperature mixing, improve mixing efficiency, storage stability and other advantages, increasingly received attention in the industry, has been widely used in rubber products.
