Product Description

Good whiteness kaolin china clay kaolin for white cement

On the surface, it looks unremarkable. A platy soft white clay mined and processed by Chuangsen in Hebei, kaolin can hide just how versatile and vital it is to a diverse list of industries by appearance alone.
 

1. High brightness, particle size and super opacity, as pigments and fillers in paper industry, kaolin can improve the smoothness, gloss,coverage and opacity to reduce or eliminate TiO2 to cut down cost whilst maintaining key properties.

2. Low abrasion, effectively reducing knife consumption to cut down cost.

3. Favorable viscosity and good compatibility with various chemical agents.

Uses
Kaolin is a platy white clay that is chemically inert, nonabrasive and possesses a number of characteristics that make it desirable for use in a range of industries, including paper and paperboard, paints and coatings, plastics, wire and cable and in concrete among many others.

Kaolin improves the quality of coated recycled board by enhancing the printability of the board, increasing opacity, adding gloss and producing higher brightness and whiteness.
 
Kaolin 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 Used for Paint and Coatings
 
While 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 Used for Wire and Cable
 
The 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 often
