Good Sound Absorption Mineral Fiber

good sound absorption 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 fiber hasproperties 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.It is anew environment friendly and non-asbestos reinforced materials, mainly used for production of brake discs, brake pads,brake drum sheet.SPECIFICATIONS:Model:XGRW01Color:celadonFiber length:0.3mm-0.8mmFiber diameter:3um-15umShot content:≤4%Melting point:≥1000ºCTensile strength:1300-1500MPaMOHS hardness:5Specific surface:0.3m2/gSpecific density:1.76g/cm3LOI:≤6%Moisture content:≤1%SiO2:40%-45%Al2O3:14%-25%K2O+Na2O:4%-6%CaO+MgO:21%-25%Fe2O3:4%-6%
