What is silicone rubber fiberglass cloth?

Silicone rubber fiberglass composite cloth is a high-temperature and high-strength glass fiber cloth as the base material, which is compounded by silicone rubber through a special process. It is a high-performance, multi-purpose composite material. It has been widely used in aerospace, chemical, petroleum, large-scale power generation equipment, machinery, metallurgy, electrical insulation, construction, transportation, and other fields.

Glass fiber coated silicone rubber products are a new type of composite material, which has been widely used in construction, electrical insulation, flexible pipe connection, chemical corrosion protection, sealing, and other fields. Mainly used in the following areas:

①, electrical insulation

Silicone rubber-coated glass fiber membrane structure material has a high electrical insulation level, can withstand high-voltage loads, and can be made into insulating cloth, casing, and other products.

②, non-metallic compensator

The non-metallic compensator is used as a flexible connecting device for pipelines, which can solve the problem of damage to pipelines caused by thermal expansion and contraction. Silicone rubber-coated glass fiber membrane structure material is used as the base material of flexible expansion joints, which has high operating temperature and anti-corrosion. And anti-aging performance, excellent elasticity, and flexibility. It has been widely used in petroleum, chemical, cement, steel, energy, and other fields, and has achieved good results.

③, anti-corrosion aspects

Silicone rubber-coated glass fiber can be used as the internal and external anti-corrosion layer of pipelines and storage tanks. It has excellent anti-corrosion performance, high-temperature resistance, and high strength. It is an ideal anti-corrosion material.

④, other fields

Silicone rubber-coated glass fiber membrane structural materials can be used in building sealing materials, high-temperature anti-corrosion conveyor belts, packaging materials, and other fields.

⑤Can be used as a fire curtain

Coating Category: single-sided and double-sided


Silicone Rubber Coated Glass Fiber Cloth Roll For Fireproof Blanket

This liquid silicone coated glass fiber cloth is coating fiberglass fabric, which coated with liquid silicone rubber on two sides. Silicone coating is flame retardant and heat resistant up to 250°C. Glass fiber cloth non-flammable and heat resistant up to 550°C. Silicone coated glass cloth provides greater life and improved resistance to abrasion, flexing, tear and puncture. The main applications of this silicone coated glass fabric are fireproof blanket, welding curtains, removable insulation pads, jackets, flange and valve covers, equipment covers and compensators.
