The character of Feldspar:
Quartz is mainly refers to quartz sandstone, quartzite and vein quartz. Quartz crisp, no cleavage, conchoidal fracture, oily luster, milky white or colored translucent or other colors.Quartz chemical stability, resistance to high temperature, acid, slightly soluble in potassium hydroxide solution. Quartz belongs to the high hardness of the filler, ordinary sand is quartzite. friction industry used quartz powder is above 200 mesh, although it increase the friction effect, it also easy to cause obvious braking noise and scratches dual surface, therefore the quartz usage in the friction material industry is not much.

Product description, Product introduction:
Rubber powder is made by crushed and screened
methyl vinyl silicone rubber pieces The rubber powder used for friction materials in order to improve the friction performance, improve the friction coefficient and reduce noise.
The character of rubber powder:
The rubber is used as auxiliary materials, the purpose is to reduce product of hardness and elastic modulus, improve the toughness and impact strength. In brake rubber, the formula of the rubber consumption may be equal to or more than resin usage. The main Ingredient of the rubber binder is rubber, while phenolic tree as auxiliary Ingredient. The rubber has good elasticity, elastic temperature range from 70 �?? to 130 �??.The rubber has excellent flexing resistance, flexible about more than 206 times. Rubber has good abrasion resistance, cold resistance and insulation. If brake material is harder, it is easier to cause braking noise. When add rubber ,it reduces the material hardness and enlarge the adhesive surface to obviously reduce the brake noise. As the main made of soft brake pads products of which the binder is mainly made by Rubber belong to low noise or non-noise friction materials

Product description, Product introduction:
Nitrile butadiene rubber powder(NBRP),density is
1.5 g/cm3,melting point is 1450.Nitrile butadiene rubber powder has good insulation performance, good oil resistance, water resistance, heat resistance, aging resistance, and good chemical stability
The character of Nitrile butadiene rubber powder(NBRP)
:
The heat resistance and strength of the nitrile butadiene rubber is better than that of styrene-butadiene rubber.
Nitrile butadiene rubber solubility parameter is of 9.3-9.9, which means that the nitrile butadiene rubber and thermoplastic phenolic resin has good intermiscibility.
Nitrile butadiene rubber is commonly used friction material in rubber to satisfy the high performance requirements.
Nitrile butadiene rubber powder(NBRP) is used in car brake pad, heavy duty truck brake pads and engineering mechanical friction plate, urban public transport vehicle brake pads. The stronger the oil resistance and solvent resistance of Nitrile butadiene rubber powder(NBRP) is,the better mechanical properties. So NBRP is more and more widely used.

Product description:
Lead zinc ore is gray and black powder, and is made by selected and crushed sphalerite and galena sulfide ore.The mohs hardness is 3-5.5, the density is 4.5- 5.0 g/cm3.For the different melting point of sulfide, lead zinc ore is used in friction material for adjusting high-temperature, improving friction coefficient and reducing the dosage of adhesive.It is specially suitable for rake pad drum brake or clutch.The recommended regular consumption rate is about 2-8% according to the required function.
Product description, Product introduction:
Cryolite is double salt of sodium fluoride and aluminum fluoride. The chemical formula is 3AaF·A1F3. Cryolite stone is soft, waxy luster, hardness is 2.5 to 3, the gravity is from 2.95 to 3.01, and the color is white. The cryolite can improve process performance, improve friction coefficient and extend the service life of lining.
The character of Fluorite:
Cryolite is of natural and artificial two kinds. Natural cryolite is associated with granite.Producing method of producing artificial cryolite is as below: adding the sulfuric acid in fluorite, heating to make it produce hydrogen fluoride, and then make the sodium aluminate react to made cryolite. In addition, the phosphate rock also can be the raw material to produce artificial cryolite. In the process of manufacture phosphate fertilizer, recycle fluorine from the ore, and react with sodium hydroxide, then make the aluminum hydroxide react to make cryolite.
