Calcined kaolin
Calcined kaolin
Product Name：Calcined kaolin
Chemical Formula：Al2O3·2SiO2·2H2O
Relative Atomic Mass：258.16
C A S NO.: 1332-58-7
EINECSNO.: 265-064-6
H.S.Code:2507001000
product introduction：White powder.
introduction：Because of the high purity of kaolinite, very low levels of harmful elements, simple processing technology, high whiteness, The average whiteness can reach 93%. The highest whiteness can reach 97%. Used for paper making can improve the whiteness of coated paper, Instead of some titanium dioxide, Cost reduction. High viscosity, up to 74%, Good dispersion and good coverage. It has good compatibility with natural and synthetic adhesives and other additives in the formula. Can make coating has very good rheological property. It is especially suitable for coating machine with high solid content. Low abrasion value, uniform heating of materials. There will be no local overburn. The tested abrasion value was only 3.6mg/2000 times.
Application：Suitable for high grade paint, coating, ink, rubber, plastic, wire and cable, etc.
1. Paper, coating can replace part of the expensive titanium dioxide.
2. Paints, water-based latex coatings.
3. Rubber and special cable reinforcing agent. Industrial plastic function filler, ink, food, medicine, cosmetics filler.
4. High quality porcelain and special ceramic materials.
