2741 Fiberglass sleeving coated withe Polyurethane

(In accordance with Q/CGJD05-2008,IEC60684-3-409)

Fiberglass sleeving coated with polyurethane is manufactured with non-alkali fiberglass braided sleeving and coated it with acryl ate latex and polyurethane and then heated it to form F grade insulating sleeving. It possesses reliable heat resistance, good qualities of dielectric, excellent softness and elasticity. It can be used for wiring insulation and mechanic protection for F grade electrical machinery electric appliances.
