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.

RWT-R Rubber Internal Releasing Agent

Chemical composition: mixture of surfactant and internal and external lubricants.Appearance: white or with little yellow particle Quality indicator: 1．Melting range：85～100℃ 2．Ash≤7%Function:1．Added with rubber according to the recommending recipe, this product can demould effectively without spraying any external releasing agent, and automatically keep sparkling clean. The pollution during the rubber mixing as well as the stain and corrosion to the mold should be avoided so that the life of the mold can be prolonged.2．This product will not bloom and at the same time, it can avoid self-vulcanization when the temperature of the rubber compound

is too high.3．This product is a kind of rubber internal releasing agent that has the dispersion and the demoulding function. Through reducing the viscosity of the rubber compound and improving the sliding between the rubber compound and the metal interface, it is helpful to solve the problem caused by the internal friction of the rubber and the adherence between the mechanical molds so as to improve the success rate of the production.4．This product can be used to complicated mold and casting vulcanized production. It can improve the flowability of the rubber in the mold, help the rubber fill the mold and is helpful for the production to demould after vulcanization.5．This product can increase the flowability of the rubber when extruding, make the extrusion speed increase, and the die swell is

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

small, the dimension stability is good and can improve the smoothness of the production.6．This product is applicable to the production of all kinds of thermoplastic elastomer.
