self-extinguishable fiberglass sleeving　 　　 　
　　　Self-extinguishable fiberglass sleeving treated at a high temperature is the sleeving braided with non-alkali fiberglass and coated with a special kind of silicone resin.Self-extinguishable fiberglass sleeving possesses good qualities of dielectric, Self-extinguishment, excellent softness and elasticity. It is widely used as wiring insulator for H grade electrical machinery, domestic electrical appliances, heating electric equipments, TV sets, and electric apparatus, and also for the protection of collected strands of wire
