Bentonite Coated Fiberglass Fabric: Application and Advantages of High-Performance Industrial Materials

Vermiculite Coated Fiberglass Fabric is a high-performance composite material made of a glass fiber fabric substrate coated with a Vermiculite coating. This material combines the high strength and heat resistance of glass fiber with the chemical corrosion resistance and high temperature resistance of bentonite, and is widely used in high temperature environments, industrial insulation and fire protection.

Composition of Bentonite Coated Fiberglass Fabric

Glass Fiber Substrate
Glass fiber is a fabric woven from long and thin glass filaments with high strength, flexibility and good heat resistance. It can usually withstand temperatures above 500°C and maintain structural integrity.
Bentonite Coating
Bentonite is a natural material composed of silicate minerals. After high-temperature treatment, it forms a coating with excellent fire resistance and oxidation resistance. Bentonite coating can also enhance the chemical corrosion resistance of the fabric.

Main features

High temperature resistance
The bentonite-coated fiberglass fabric can withstand continuous high temperatures up to 800°C and withstand higher temperatures for a short period of time, making it suitable for scenarios that require high temperature protection.

Abrasion and chemical corrosion resistance
The bentonite coating increases the surface hardness of the fabric, making it less prone to wear in high temperature environments, and has strong corrosion resistance to acids, alkalis and other chemicals.

Insulation and fire protection
This fabric has a good thermal barrier effect and is one of the important materials for fire protection. It can be used as a filling material for fire blankets, insulation pads and fire doors.

High strength and flexibility
The fiberglass substrate provides extremely high tensile strength and excellent flexibility, making it easy to process into various shapes and sizes.

Application areas

Industrial insulation
In the metallurgical, steel and power industries, bentonite-coated fiberglass fabrics are often used to make insulation covers and insulation pads for high-temperature equipment to reduce heat energy loss.

Fire protection and safety protection
Due to its excellent fire resistance, this material is used to produce fire blankets, fire curtains and other safety protection products.

Exhaust and Sealing
In the automotive and aviation industries, this material can be used as a high-temperature exhaust pipe covering material or sealing material to provide reliable thermal protection.

Construction Field
Bentonite-coated glass fiber fabric is also used in fire protection systems in buildings, such as fire door filling layers and fire-resistant wall reinforcement materials.

Advantage Comparison
Compared with traditional glass fiber fabric, bentonite coating enhances the material's fire resistance and corrosion resistance, making it more suitable for extreme working conditions. Compared with silicone-coated glass fiber fabric, bentonite coating shows better stability and heat resistance in high temperature environments.
