Braided Fiberglass Sleeve—— Reliable protection of high temperature and electrical insulation

Braided Fiberglass Sleeve is a flexible tubular material made of alkali-free glass fiber yarn through a braiding process. It has excellent high temperature resistance, electrical insulation and mechanical strength. It is widely used in various industrial fields to meet the protection and insulation needs of cables, wires and pipelines. With its excellent heat resistance, electrical insulation and structural flexibility, braided fiberglass sleeve has become an indispensable part of the safety protection of modern industrial equipment. Whether in high-temperature electric heating equipment or in complex electronic systems, it can provide a stable and reliable protective barrier.

Product Features

• Strong high temperature resistance

Glass fiber itself has excellent heat resistance and can withstand a working temperature of 450℃ for a long time. After special coating treatment, it can withstand higher temperatures (such as silicone resin coating up to about 550℃).

• Good electrical insulation

Glass fiber has natural electrical insulation ability, which can effectively prevent arcs and short circuits. It is widely used in electric heating pipes, cable harnesses and other occasions.

• Soft but strong

The woven structure maintains flexibility, is easy to install and wrap, and has good tensile strength and wear resistance.

• Flame retardancy and chemical corrosion resistance

It does not support combustion, does not melt when exposed to fire, and is oil-resistant and chemical-resistant, suitable for complex industrial environments
