Plasticizer A LTS-82A 86A is a mixture of high molecular weight aliphatic polymers containing unsaturated bonds and active agents. The product does not affect the physical properties of the rubber compound, and has the property of reducing the Mooney viscosity and shortening the mixing time, and the hardness of the finished product is not affected. Inorganic fillers such as carbon black and white carbon have high-performance dispersion, improve extrusion and injection properties of rubber compounds, smooth surface, and significantly reduce internal porosity. This product can reduce the heat generation of the rubber compound, reduce wear, improve tire life and reduce energy consumption.
