High Purity 99.99% Sio2 Quartz Wool with Excellent Insulation Performance 50g

* High Quality Quartz Wool MICQ Quartz Wool is made from pure fused quartz fibers which are amorphous, continuous, tangled, white, odorless, without volatile component and no shot. Length, shape and arrangement of fibers give the wool its curly appearance preventing compression of the padding and improves its desired insulating properties. * Properties: 1.High temperature resistance(1100°C long term, and at 1500ºC in a short working time.)2.Low expansion coefficient3.High electrical resistivity4.Low dielectric constant and loss5.High strength6.High corrosion resistance * Specification: Diameter:1-3um, 3-5um, 5-8um, 8-15umHardness: 6-7 MohsMoisture Content: ≤0.4%Burn Loss Rate: ≤0.1%Shape: Fine and Soft CottonWorking Temperature: Over 1100ºCMelting Point: 1700ºCResistivity coefficient: 0Dielectric Coefficient: 3.74Density: 2.2g/cm3SiO2 Content: >99.99%Resistance Strength: 3790MPaFunction:Filling material for analytical instruments or laboratory small-scale
