Kaolin clay Used for Specialty Paper
Kaolin additives enhance specialty paper products including thermal paper, carbonless paper, label grades and ink jet paper. In items like thermal paper, kaolin increases the gloss level and wax absorption, resulting in its smooth surface which produces higher quality printouts. And in decorative laminate papers used in cabinets and on furniture and flooring, kaolin can replace significant amounts of expensive titanium dioxide, making it an economical method of increasing opacity, brightness and whiteness.Kaolin clay Used for Paint and CoatingsWhile kaolin isn't an absolute replacement for titanium dioxide, it is an excellent and economical extender, helping keep manufacturing costs down in a number of architectural paints and coatings.But the benefits don't stop there. Kaolin also offers increased opacity and tint strength, stain and scrub resistance, improved pigment suspension, sheen control and improved holdout.At Chuang Sen, we manufacture a wide range of color pigments and special effect pigments with kaolin that are designed to brighten, whiten, strengthen and visually enhance architectural features.Kaolin clay Used for Wire and CableThe quality and durability of cable insulation directly affects the performance and dependability of cable products. Using calcined and surface treated kaolin, ChuangSen has helped improve electrical and physical performance - even at high stress with elevated moisture and temperature levels.Calcined kaolin is manufactured by controlled heat treatment to remove the bound water of hydration from the crystal structure. This enhances the optical properties, abrasion resistance, electrical resistance, brightness and inertness.This not only saves electricity, but increases the cable's useful lifespan so costly replacement is needed less oftenKaolin clayPhysical information
