Calcined kaolin clay for rubber is our best pigment with high reactive powder clay. JYCK96 has good viscosity and dispersion ,and can well improve the effect of vulanization,increase the addition for its good crosslink with rubber.It has a serie of unique properties such as the acid resistivity,chemical stability,heat durability,incombusibility.It has an increasingly wide spread applicants in various fields-asbestos substitute products in rubber.
