Product Description

Industrial-Grade E-Glass Alkali-Free Dewaxed Fiberglass Cloth Various Thickness For Fire Retardant Welding Blankets

Product Description

Dewaxed glass fiber cloth is a high-performance glass fiber fabric that has undergone special high-temperature or chemical treatment to remove surface paraffin type wetting agents (sizing agents). It is a key foundational material in the fields of composite material manufacturing, electronics industry, and high-end insulation.

Ordinary glass fibers are coated with a layer of "wetting agent" during the drawing process, mainly composed of paraffin, coupling agent, and film-forming agent, aimed at protecting the fibers, reducing wear, and facilitating textile processing. However, this layer of organic matter can hinder the direct bonding between resin or other matrix materials and glass fibers.

The dewaxing process is the process of removing these organic components through specific means:

Heat treatment method: Send the fiberglass cloth into a continuous dewaxing furnace, and at a high temperature of 300 ℃~400 ℃, completely melt and evaporate the paraffin type surface pre-treatment agent, making the fibers become exposed inorganic state.

Chemical treatment method: Some processes are supplemented with acid leaching (such as using 1.5-3.5 mol/L hydrochloric acid) and water washing to thoroughly remove residual impurities, ensuring that the fiber surface is clean and highly active.

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. ‌‌
