Antimony Sulfide

The character of antimony sulfide: The melting point of antimony sulphide is 548 centigrade, it is of soft metal sulfide with low melting point. It would forms inorganic binder and have the smiliar sintering effect with sintering ceramic in at high temperature.When add with antimony sulfide, it can reduce the dosage of organic binder.As a result, the resin dosage in brke pad is only 7%-8% or even lower like 5% to 6% because add the antimony sulphide. Using antimony sulfide is good for reducing the heat recession of friction coefficient, and for reducing the high temperature wear. Antimony sulfide hardness is low, can reduce the brake noise of brake pads Property: Density: 6.6g/cm3 Antimony sulfide content: 90% Grade:200mesh, 325mesh

Wollastonite is a naturally occurring mineral with many unique characteristics. Through advanced processing, it has become one of the most versatile functional fillers in the marketplace. Wollastonite increases the performance of many products including plastics, paints and coatings, construction materials, friction, ceramic and metallurgical applications to name a few. Wollastonite is an industrial mineral comprised chemically of calcium, silicon and oxygen. Its molecular formula is casio3 and its theoretical composition consists of 48% cao and 51% sio2. Natural wollastonite may contain trace or minor amounts of various metal ions such as aluminum, iron, magnesium, potassium and sodium. Wollastonite is rarely found by itself and generally contains other minerals like calcite, garnet and diopside that are removed during processing. Optimum performance is created by properly matching the correct coupling agent at the right concentration level to the polymer system. Overall, the benefits of a surface modified wollastonite are improved physical properties, improved processing along with improved dispersion of the resin.

Product description, Product introduction: Calcite(calcium carbonate) is white powder, the main components is Cac03, mohs hardness is 3,the density is from 2.6 g/cm3 to 2.8 g/cm3. The calcium content ofCalcite(calcium carbonate) is 54%. Calcite(calcium carbonate) is used as filler in friction material in order to improve the wear resistance of the friction material and reduce the cost. Calcite(calcium carbonate) is suitable for the disc brake pads,drum brake pads and clutch.According to the performance, the reference usage of Calcite(calcium carbonate) is generally from 2% to 8%. The character of Calcite(calcium carbonate): According to the performance, the reference usage of Calcite(calcium carbonate) is generally from 2% to 8%. Calcite(calcium carbonate) is rich in the east, south, middle stratum of our city.The ore body is associated with marble and its fracture zone and it belongs to the low temperature hydrothermal type ore body. The calcite in the place YanZu is of three mineralization belt, the belt is 3000 meters long, 10m to 30m width. Calcite is colorless, milky white, some even have high transparency. Since many years, the Daye government organize to develop the calcite mining and the mining scale is very large. Now there are 40-50 calcite factories, some can manufacture modified ultrafine powder. The calcite can be divided into level 1, level 2 and level 3 according to the impurities content. Some calcite can be as ornamental stones, some with the excellent transparency and unique crystal can be optical materials for sale.
