ATH (aluminum hydroxide) is named “Chinawhite” and well known of the lower ironand high brightness. the chemical alumina has some characters such as innocuity, flame-retardant and unique optics character (refractive index is 1.57），it makes the series products usein many fields. In order to meet different and individualize requirements, our company has kinds ofproducts from standard particle size to fine size in stock. We has three seriesdry-white high-white and super-fine aluminum hydroxide more than ten kinds ofchemical alumina products ( it is also called special aluminum hydroxide).
Usage：
1. Filling for thesolid surface (the artificial marble). When filled in the resin, the slimy islow. Under the common temperature, the harden time is rapid.
2. Flame retardantfillings for PVC, epoxy resin, polyester resin, polyurethane resin, polyvinylchloride resin and electrical compound with properties of flame retardant 、smokesuppressing 、modification andnontoxic. In addition, the flame retardant and smoke suppressing is moreeffectiveness after processing the surface.
3. Basic raw materialfor toothpaste, being rational polishing agent of high and median gradestoothpaste, and modest in hardness and good in taste
4. used in making catalyzer and carrier.
5.The filling of coat paper and the flame retardant paper. The surface of coatpaper is smooth and has luster to absorb the printing ink strongly.
6. Filling of makeup.
7. Thefillers of artificial agate boulderartwork.
