The kind of fiberglass sleeving is the non-alkali fiberglass braided sleeving coated with polyvinyl chloride resin.It is produced with the process of thermoplasticization.The polyvinyl chloride fiberglass sleeving possesses good qualities of dielectric.chemical resistance.excellent softness and elasticity. It can be used for wiring insulation and mechanical protecton for electrical machinery.electrie appliances.electrical instruments and apparatus.medical instuments and apparatus.wireless sets. TV sets and domestic electrical appliances of electrical fans, washing machineetc. length: 1000(+20 or -10)mm (Continuous length may be negotiated.)
