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
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.
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.
