 聚氨脂玻璃纖維套管

詳細說明:PUG-301

2741聚氨酯玻璃纖維軟管(符合滬Q/JBQR23-2001) 

2741 Fiberglass Sleeving Coated With Polyurethane (In According With Shanghai Q/JBQR23-2001)  

    聚氨酯玻璃纖維軟管系采用無堿玻璃纖維編織成管,并涂以改性聚氨酯樹脂經加熱烘干而成的F級絕緣軟管。具有可靠的耐熱性,良好的電性能,較好的柔軟性和彈性。適用于做F級電機、電器及儀表、無線電、家用電器等裝置的布線絕緣和機械保護。

   長度:1000( )毫米(連續長度由供需雙方協議)。 

 

    Fiberglass sleeving coated with polyurethane is manufactured with non-alkali fiberglass braided sleeving and coated with a layer of polyurethane and than thermoset to form F grade insulating sleeving.It possesses reliable heat resistance,good qualities of dielectric,fair softness and elasicity.It can be used for wiring insulation and machanic protection for F grade electrical machinery,electric appliances,electrical instruments,wireless sets and domestic electrical appliances.

    Length:1000( )mm(continuous length can be negotiated).
