XR-H 双壁热缩套管(XR-H Dall HEAT SHRINKABLE TUBES)
描述: XR-H※ 双壁热收缩套管内层附有热熔胶的半柔性热缩管,
外层是由辐射交联聚烯烃组成,内层是专门设计的
胶性内壁;加热时内壁熔融,并随外壁收缩填充孔隙
或缝隙,冷却后,双壁管壁厚均匀,结实.
※ 阻燃级别: UL224 VW-1
※ 产品具有低温收缩、柔软、阻燃、防水防潮、耐油
耐酸等优点.
※ 产品收缩比率:2:1 3:1 4:1
用途:本产品广泛应用于电子设备的接线防水,电线分支处的密封固
定,金属管线的防腐保护,以及防止由高分子链松弛产生的松动
和脱落,如水下灯饰,汽车刹车油管,高级线束的防腐保护.
