Synthetic Barium Sulfate

Synthetic Barium Sulfate HTS-H

HOTEN SUPER FINE HTS is a chemically synthesized barium sulfate product (BLANC FIXE) refined through special manufacturing processes with highly pure barium salt and sodium sulfate as its raw materials. Its grain sizes are under strict control in the course of reactions and synthesis and content of impurities is minimized. It features low specific weight, gentle and stable nature, narrow distribution of grain sizes, extremely good light fastness, weathering resistance and other outstanding chemical properties.

The uniquely spherical or near spherical ( D*0< 1.0um ) ultra-fine barium sulfate crystal grains of HOTEN SUPER FINE HTS are provided with big specific surface areas, thereby effective increasing or magnifying the light reflecting area in coating. Therefore it is widely applied in the formula system of high-gloss products.

By using its own ( *5g / **0g ) low oil absorption, HOTEN SUPER FINE HTS may be fully mixed with other resin components, i.e. the same equivalent weight of resin may carry more HOTEN SUPER FINE HTS. In particular, it gives a vivid color, repeatable tint and perfect surface gloss when compounded up with pigment in a formula. Its low consumption of base material guarantees the high rheological property in system and good mechanical property of finished products.

This embodies the cost effectiveness of using HOTEN SUPER FINE HTS and greatly facilitates your advantages of costs. On the contrary, when barium sulfate has a relatively high oil-absorbing index and there is no adequate resin base material to coat and bond pigment particles, the resin base material fails to moisten all pigment particles so that they loosely distribute in coating, resulting in deterioration of coating quality.

HOTEN SUPER FINE HTS may be used for thermoplastics to improve the rigidity, hardness and abrasion resistance of plastic products.

HOTEN SUPER FINE HTS is approved for the product subject to contacting food due to its nontoxic property. HOTEN SUPER FINE HTS conforms to the Europe 's purity requirement and U.S' codes of food and drug administration. LD5 (Mouse, oral administration) >*5,**0mg/kg; dust limit=6mg/m 3 .

HOTEN SUPER FINE HTS is free from impurities hazardous to elastomer. Hence HOTEN SUPER FINE HTS is particularly suitable to the filler for elastomer. Its other advantages include outstanding rheological property, low abrasiveness and high chemical purity.
