Rubber Processing Aid Series

(This product has passed the inspection and authentication of EU RoHS and Germany PAHs)

The rubber processing aid is a kind of material to improve the operating performance in the processing. In other words, the rubber processing aid can improve the processing property by adding a small amount into the rubber, and it only has physical effect on the rubber without any chemical reaction, and can not finally influence the physical property and vulcanizing property of the rubber. Adding a small amount of rubber processing aid can change the rubber processability, including the mixing, calendering, extrusion and other property on the open mill or the internal mixer, such as the plasticity, dispersity, flowability, lubricity, uniformity, roll wrapping property and scorching property, etc., and have no or few impacts on the physical property of the vulcanized rubber, and improve the dispersity of the padding and shorten the mixing time.

Rubber internal releasing agent is a kind of internal and external lubricant, the main function of the internal lubricant is to undermine the friction between the polymer and the internal molecule of the volume, reduce the interior heat build-up and improve the melt flowability. While the functions of the external lubricant are mainly embodied on the surface of the rubber particle as well as on the surface of the machine tooling, so as to serve as boundary lubricant and demoulding; it is the above-mentioned internal and external lubricant that increases the flowability of the rubber and reduce the pollution of the mold, which is easy to demould.

The rubber dispersant is mainly used to improve the powder dispersion of the rubber. The dispersant works through the surface of the lubricant, wet powder particles or elastomer, reduce the relative movement friction between the powder particles of different property and different category or the relative movement friction between powder particles and the elastomer, improve the compatibility of the particles, make the powder disperse evenly in the rubber and improve the processability of the rubber.
