Why is rubber additive pre-dispersion a development trend?

First, why is the rubber assistant predispersion the development trend?

Rubber auxiliaries are chemicals that bring higher added value to rubber products and can reduce costs. However, the traditional rubber additives not only produce a lot of dust and toxic and harmful gases when used, which bring 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.

Two, rubber additives predispersion definition

Rubber auxiliary pre - dispersion, also known as rubber auxiliary mother colloidal. The pre-dispersed rubber agent is a polymer (generally EPDM, SBR, NBR, EVA) as the carrier, adding rubber agent and softener, through a special process to pre-disperse the traditional rubber agent into the polymer, to obtain a certain concentration of uniform pre-dispersed body (extrusion granulated). The pre-dispersed rubber additive is the upgrade replacement of the traditional rubber additive. It has the advantages of no dust, easy dispersion, suitable for automatic weighing and automatic continuous low temperature mixing, improving mixing efficiency and good storage stability. It has been increasingly paid attention to by the industry and has been widely used in rubber products.
