High Silica Fabrics is a kind of heat-resistant,insulating and soft special fiberglass fabric with easy processing ,versatility, heat resistance, insulation, softness and can be used as high temperature resistant, ablation resistant, heat insulation and heat preservation material. Additionally,it could withstand temperatures exceeding 1000° C (1832° F) without significant degradation and the instantaneous heat resistance temperature can reach 1450° C. Our High Silica Fabrics is widely for heat preservation and protection, sealing, fireproof materials, such as welding curtains, fire shutters, fire blankets, fireproof clothing, heat insulation curtains, steam pipeline heat insulation, metallurgical casting insulation protection, kiln and high temperature industrial furnace protective cover, wire and cable fire insulation, etc.
Feature:
Excellent High - temperature Resistance:
With a SiO₂ content exceeding 96%, its softening point is close to 1700°C. It can be used continuously at 1000°C and maintain integrity under an instantaneous high temperature of 1400°C.
Low Thermal Conductivity:
It has good heat - insulation performance, effectively blocking heat transfer and reducing heat loss. It can be used for heat - insulation and thermal insulation of high - temperature equipment.
Good Chemical Stability:
It is inert to the vast majority of chemicals and has strong corrosion resistance. It can maintain stable performance in harsh chemical environments such as acids and alkalis, making it suitable for high - temperature protection in the chemical industry and other fields.
Excellent Electrical Insulation:
It is a good electrical insulating material. It can maintain good insulation performance under high - temperature and high - pressure conditions and is applicable to the electrical insulation field.
Low Thermal Shrinkage Rate:
It has a small dimensional change at high temperatures, maintaining good dimensional stability, which ensures its use effect in high - temperature environments.
Application:
Industrial Field:
It is often used for high - temperature heat insulation, insulation, and sealing, such as heat insulation and sealing of industrial furnaces, pipelines, and equipment. It can also be used for the filtration and purification of molten metals, effectively removing impurities and inclusions in molten metals.
Building Fire Prevention:
It can be used to manufacture building fire - proof curtains, fire - fighting blankets, fire - proof doors, fire - and - smoke - blocking curtains and other fire - proof materials. In case of a fire, it can block flames and smoke, protecting the safety of people and property.
Aerospace:
As a heat - resistant and ablation - resistant material for rockets, missiles, and spacecraft, it can protect the structure and equipment of the aircraft in a high - temperature and high - speed flight environment. It can also be used for the fire - proof and heat - insulation of cables in nuclear power plants.
Automotive Field:
It is used for noise reduction, heat insulation, and exhaust gas filtration of automobiles and motorcycles. It can reduce vehicle noise and improve vehicle comfort and environmental performance. It can also be used as a heat - insulation material for automobile exhaust pipes to reduce heat transfer to the vehicle interior.
Fire - fighting Industry:
It can be used to make fire - fighting suits, fire - extinguishing felts and other fire - fighting equipment, providing effective protection for firefighters in fire - fighting and rescue work.
Filtration Field: It is used for high - temperature gas dust collection and liquid filtration, effectively.
