The Introduction of Volsun Fiberglass Sleeves
The silicone rubber glass fiber sleeve is with UL certificated, RoHS & REACH compliant, made from alkali-free glass fibers woven into a tube and then coated with silicone rubber before being cured, is a highly specialized material designed for high-performance insulation applications. This product combines the excellent dielectric strength of glass fibers with the flexibility, heat resistance, aging resistance, and flame retardancy of silicone rubber, making it an ideal choice for environments where high temperatures are common.
One of the key features of this sleeve is its ability to withstand temperatures up to 200°C, which makes it suitable for use in various high-temperature applications. The sleeve's construction involves extruding silicone rubber over the woven glass fibers, followed by high-temperature curing, which enhances its mechanical properties and ensures long-term reliability under harsh conditions .
The silicone rubber glass fiber sleeve is widely used in the new energy vehicle sector, where it provides effective insulation and protection for electrical components exposed to high temperatures and mechanical stresses. Its application extends to special vehicles, rail transit systems, military aerospace, and other industries that require robust electrical insulation solutions.
