Fiberglass Needled Mat |
Fiberglass needled mat comprised of high purity E-Glass fibers. Chopping in 3cm-8cm fiber by guillotine machine. And then puffed, carded and continuously needled by thousands special needles. Fiberglass needled mat comprised of inorganic E-Glass fibers. It mainly contains siliceous alumina and calcium oxide. Has excellent quality on heat insulation efficiency, obdurability, fireproofing, non-corrosiveness.Specially excellent in electrical insulation. Fiberglass needled mat needled by e-glass. The resulting product has large number of minute air spaces and excellent sound absorptionSpecification:Thickness (mm)3mm-30mmWidth (mm)≤2800Length (mm)20000-30000Weight of unit acreage(g/m2)600-4900Density (kg/m3)100-300Performance: 1.Heat performance light performance:Inorganic, non-combustibility 2.The coefficient of linear thermal expansion:48X10-6cn/cm/°C 3.Specific heat:0.19cal/9°C 4.Heat exchange rate:0.19kcal/m.h°C 5.Softening temperature:850°C 6.Refractive index:(25°C):1.55 7.Mechanical Properties:fiberglass bears high tensile strength and stablility 8.High tensile strength:350kg/mm2 9.Modules ofelasticity:7300kg/mm2 10.
