fiberglass sleeving coated with silicone elastomer

　　This kind of fiberglass sleeving is manufactured by the non-alkali sleeving braded with fiberglass and coated with silicone elastomer ,then heated and vulcanized. It is of some dielectric, high heat-resistance (200℃), good elaslity and cold-resistance. It can be used for wiring insulation and as mechanic protection for electrical machinery and electrical appliances with high demand.

Temperature Classification: H
Standard: GB7115-86
　　
1．Appearance: sleeving smooth surface，clear and neat ends.
　　2．Length: usually as(1000+20)mm/(1000-10)mm , other continuous length should be made as requirement
