2715 PVC fiberglass sleeve
PVC coated fiberglass sleeving uses an alkali-free glass fiber tube coated with modified polyvinyl chloride resin to be plasticized.
It has excellent softness and elasticity as well as good dielectric properties and chemical resistance.
Applications:
Suitable for wiring insulation and mechanical protection of motors, electrical appliances, instruments, radios, etc.
Availability:
-Length: 1000+20/-10mm. Continuous can be supplied on request.
-Colour: Special colour can be produced on request.
