Product Description

Processing High Temperature Resistant Glass Fabric Thermal Insulation Welding Protection Heat Treated Fiberglass Cloth

Product Description

Fiberglass fabric is a high-performance, woven textile composed of extremely fine strands of glass fibers. These fibers are produced by drawing molten glass into continuous filaments, bundling them into yarns, and weaving them into fabrics. The result is a material that combines the durability of glass with the flexibility of cloth, making it highly effective for insulation and fire protection.

Fiberglass is primarily composed of silica (SiO₂), the same mineral that forms natural glass. To enhance performance, other oxides are added, such as:

Alumina (Al₂O₃) – increases strength and hardness

Calcium oxide (CaO) – improves chemical resistance

Magnesium oxide (MgO) – adds stability under heat

This unique chemical composition is what gives fiberglass fabric its exceptional thermal resistance, mechanical strength, and non-combustible nature.

Features

Excellent resin permeability: After removing wax, the fibers are exposed, allowing epoxy resin, silicone resin and other matrix materials to fully penetrate, significantly improving the dry and wet mechanical strength of the laminated board and avoiding delamination defects.

High temperature resistance and thermal stability: No organic wax residue, long-term use temperature can reach 300 ℃~500 ℃ (depending on the glass fiber model), instantaneous temperature resistance is higher, and no volatiles or carbonization are produced at high temperatures, with good dimensional stability.

High electrical insulation performance: no conductive impurities on the surface, stable dielectric performance, high breakdown voltage, suitable for high-frequency circuit substrates and high-voltage electrical insulation wrapping.

Clean and dust-free surface: After dewaxing and subsequent water washing treatment, the fabric surface is smooth, hairless, and stain free, reducing fiber dust and facilitating subsequent coating and laminating processes, resulting in a smoother appearance of the finished product. ‌‌

Color characteristics: After dewaxing treatment at 300 ℃~400 ℃, the finished product usually appears golden yellow or light brown, which is different from white or light yellow cloth that has not been dewaxed.

Chemical stability: retain the inherent acid and alkali resistance, corrosion resistance, non combustible characteristics of glass fiber, strong anti-aging ability, and long service life.

Processing adaptability: The texture is relatively soft (compared to untreated stiff fabric), easy to cut, sew, and punch, suitable for complex shape forming. ‌‌
