硅橡胶玻璃纤维(内纤外胶)套管,是由无碱玻璃纤维纱编织成管后,涂以硅橡胶高温处理而成。具有比硅树脂玻璃纤维套管更良好的介电性、自熄性和柔软性，广泛应用于H&N级电机、家用电器、电热设备、特种灯具等绝缘保护。
Silicone rubber fiberglass sleeving(inside fiber and outside rubber) is weaved into tubes, then formed the product by painting with silicone rubber under high temperature. It has excellent dielectric, automatic flame off-self, and softness feature than silicone fiberglass sleeving, widely used in the class H&N motor, household electrical appliances, heating equipment, the special lamps and lanterns, TV set and electric instrument.
