1. Why is the pre-dispersion of rubber additives a development trend?

Rubber additives are chemicals that bring high added value to rubber products and can reduce costs. However, traditional rubber additives not only generate a large amount of dust and toxic and harmful gases during use, which bring great harm to the environment and the health of operators, but also have poor compatibility with rubber and are difficult to disperse evenly, which affects their use effect.

2. Definition of pre-dispersion of rubber additives

Rubber additive pre-dispersion, also called rubber additive masterbatch. Pre-dispersed rubber additives are based on polymers (generally EPDM, SBR, NBR, EVA) as carriers, plus rubber additives and softeners, and pre-dispersed traditional rubber additives into polymers through a special process to obtain a certain concentration of rubber additives. Homogeneous pre-dispersion (extrusion granulation). Pre-dispersed rubber additives are an upgraded product of traditional rubber additives. They are dust-free, easy to disperse, suitable for automatic weighing and automatic continuous low-temperature mixing, improve mixing efficiency, and have good storage stability. They are increasingly valued by the industry. It is widely used in rubber products.
