Product Description
Basalt Fiber Cloth with Excellent Functional Properties
- High strength: Basalt fiber cloth has high strength and can meet the needs of a variety of structural materials.
- High temperature resistance: Basalt fiber cloth has excellent high temperature resistance, short-term temperature resistance can reach more than 1000℃, and can be used for a long time in a temperature environment of 760℃. It is an ideal material to replace asbestos and glass fiber cloth.
- Flame retardant: Basalt fiber cloth has permanent flame retardancy, is not easy to burn, and does not produce harmful gases during combustion.
- Insulation: Basalt fiber cloth has good electrical insulation properties and is suitable for electrical insulation.
- Weather resistance: Basalt fiber cloth can maintain stable performance even in a strong ultraviolet environment.
Types of Basalt Filter Cloth
Compared with glass fiber, basalt fiber fabric is a material with higher tensile strength. Although its weaving property is slightly worse than that of carbon fiber, it is still a good alternative due to its low price and environmental protection. The structure of basalt filter cloth fiber fabric mainly depends on its weaving method. Common weaving structures include:

Plain weave
It is interwoven with one warp yarn and one weft yarn. The fibers cross more and constrain each other, making the fabric stronger and more wear-resistant.

Twill weave
It is woven by one warp yarn through two weft yarns, which has a three-dimensional sense and is often used for decorative products.

Satin weave
One warp yarn passes through three or more weft yarns, with a higher density, but the strength is slightly lower than plain weave and twill.
