High silica fabric is fiberglass fabric which is treated with acid treatment and calcination, so the SiO2 content will be more than 96%. The basic cloth is 850g/m2 and 0.8mm, adter post treatments this fabric will be 600g/m2 and 0.7mm. Except for SiO2 content, the treatment also improve the thermal insulation property so the fabric has higher softening point and higher density. Softening point of this 35oz/1200g/m2 high silica fabric is close to 1700℃. Working temperature of this fabric is below 1200℃ (continuously).
High silica fabric is a high strength, durable, chemical and oil resistant material with stable physical/chemical properties. It is widely used for fire, welding blanket, thermal insulation sealing application and other heat resistant covering.
