fiberglass sleeving coated with polyvinyl chloride resin

　　This kind of fiberglass sleeving is the non-alkali fiberglass sleevingg coated with polyvinyl chloride resin it is produced with the process of thermoplasticization. It possesses of good quality for dielectric, chemical resistance as well as softness and elasticity. It can be used for wiring insulation and as mechanic protection for electrical machinery, electrical appliances, electrical instruments, wireless sets and domestic electrical appliances.

Temperature Classification: B
Standard: GB7116-86
