Features :
Stable chemical properties, no changes when exposed in
the air, almost insoluble in water. Low impurity content,
even granularity, good processibility and low oil absorption
value.
Use :
Widely used in paper-making industry; in plastic
industry:composite materials, plastic pipes, section material,
plastic works and cables, in coating industry:oily paintings,
powdered coatings, waterborne coatings.
Main function:
In paper-making industry: improve the surface
luster, whiteness and paper's smoothness.
In plastic industry: can greatly increase the bonding
strength and mechanical properties of the surface of composite
materials, can plasticize the materials and can improve
the luster and quality.
In rubber industry: can increase products'streching, heat-resistant
and anti-aging properties.
In coating industry: Can increase the thickness of the
coating film, and improve the resistance to wear and weathering
resistance as well as the painting area.And it contains
no heavy metal and is the first choice as the filler for
powdered coating without heavy metal.
