The silicone rubber fiberglass sleeve (inner fiber, outer rubber) is made by braiding non-alkali fiberglass into a tube, then impregnating the outer wall with high-temperature vulcanized silicone rubber and curing it at high temperatures. Compared to silicone resin tubes, it has better elasticity, is softer, has higher temperature resistance, and stronger waterproof and moisture-proof properties. It is a Class H insulation material. It is widely used in scenarios such as new energy wiring harnesses, motors, transformers, electric heating equipment, ships, automobiles, home appliances, and high-temperature pipeline protection.
