Kaolin with high whiteness and tiny particle size, good dispersion and good compatibility with polymer compound, added to emulsion as a modified materials of rubber can improve the mechanical properties of rubber, especially elastic, flexing resistance, dimension stability, blocking performance, breaking elongation and compression deformation. In addition, kaolin can promote the barrier property, thermal stability of rubber, and improve the mechanical strength, abrasion performance and chemically stability of rubber product, and prolong hardening time of the rubber, change the chemical property such as reduce the permeability, water resistance, fire flame retardant, etc.

Kaolin can replace the silica hydrated partially or completely

◆ Using in Rubber seals and anti-seismic parts

Kaolin used in the seals and O-rings of automobile and motorcycle can reduce product compression deformation rate, improve mechanical properties. It can partially or completely replace the silica hydrated which is the most popular fortifier.

◆ Using in tyre industry

Kaolin can provide the high quality mechanical properties, and also can improve the barrier property, air tightness, mechanical properties, especially be appropriate for natural rubber inner tube.
