Description

Volsun Silicone rubber fiberglass sleeve is made by weaving alkali-free glass fiber into a sleeve, then coating the outer layer with silicone rubber. This fiberglass sleeving is commonly used in various industries such as new energy vehicles, special vehicles, rail transit, and aerospace for protecting circuits from insulation. Its outstanding heat resistance allows for use in high-temperature environments like smelting workshops, the power industry, and foundry industry. Furthermore, it is utilized for insulation protection in H class motors, household appliances, electric heating devices, and special lamps.


What's more, silicone fiberglass braided sleeves not only offer excellent insulation properties but also exhibit good corrosion resistance, aging resistance, and flame retardancy. These qualities allow them to remain flexible and elastic even in high/low temperatures (-40°C~200°C) without being affected by temperature fluctuations.

As a professional fiberglass sleeves manufacturer, special sizes, colors, length and package are available on request. Free samples also can be provided for testing.


Fiberglass Protection Sleeves for Wire Harness Insulation are designed to provide excellent protection for wires and cables in various industrial and commercial applications.
