SILIGLASS® High Temperature Textiles are composedof silica fibers and specifically designed to replace
asbestos in a variety of high heat applications．
The various forms of the SILIGLASS® textile group
have excellent thermal insulation characteristics overa wide temperature range and can not be melted until
temperatures exceed 1,700℃．
Moreover, with its excellent resistance to thermalshock， chemical stability and electrical resistivity，
SILIGLASS® has been used increasingly in manybranches of industry．
All SILIGLASS® textile forms（ cloth， tape， sleeving，rope，yarn and wool）have the same basic chemical，physical and mechanical features．

Characteristics■ Asbestos Free
■ Fireproof
Capability of operating at 1,000℃ continuously．

■ Electrical Resistivity■ Resists Thermal Shock■ Non−Hazardous■ Resists Chemicals
Good Stability against all chemicals except forhydrofluoric acid，caustic soda，causticpotash，etc．

■ Cost Effective■ Minimal Shrinkage■ Resists Molten Steel■ Good WorkabilityApplications■ High temperature thermal insulation andabsorption material
Welding ＆ Burning Protection Drop Cloth，
Welding Curtains，Furnace Curtain，Heat Treat ＆Stress Relief Insulation■ High temperature filter media
Filter media for hot gases and chemicals．

■ Wicks of oil heater■ Catalytic carrier for oxidation−reduction reaction
Catalytic carrier of deodorization equipment．
Treating material for organic solution gas.
■ Others
Electric cable insulator for hair driers．
High temperature buffers and seals．

■ High temperature structural materials
Rocket nose cones，etc．

ClothSILGLASS® cloths are very flexible with excellent
drapability and offer a wide versatility of use ingeneral industry．
These materials have the capability of operating at
1,000℃ continuously．
Especially，the new U and AD types，exhibiting
tensile strength and abrasion resistance evengreater than conventional silica fiber．
