Heat resistant mineral wool fiber for building material
Mineral fiber is kind of inorganic fiber made of basalt as main material,been melted at 1100 ºC high temperature by furnace, through techniques like spinning blowing legislation, winnowing Cleaner,
organic coupling,surface treatment and high-speed cutting.
This kind of mineral fiber has properties of light weight, low thermal conductivity, good sound absorption, non-flammable, chemical stability. Fiber designed formula is based on friction coefficient, wear rate, impact strength and heat requirements.
Mineral wool fiber's chracteristic
1. The entire mineral wool fiber is extensively applied in industrial fields without public harm.
2. Appearance: off-white color with soft hand feeling
3. It can be used in friction material as the primary ingredient of fiber reinforcement. It's reinforcing effect can meet the demand of mechanic strength of friction material products.
4. Excellent heat-resistance
5. Low cost, help to substantially bring down the cost of asbestos free friction material,such as steel fiber.
6. Comparing with glass fibres and wollastonite, it reduces noise and judder of frriction material as well as improving the wear resistance
Main applicaiton of mineral fiber
It is a new environment friendly and non-asbestos reinforced materials, mainly used for production of
1. brake discs, brake pads,brake drum sheet
2. ther buiding materials, such as concrete mortar, gypsum products, wood pulp sponge, asphalt roads, and fireproof ceiling borad etc.
