3倍阻燃双壁热缩管/柔软阻燃双壁热收缩套管/环保双壁热缩管/阻燃双壁热缩管/防水双壁热缩管

3倍阻燃双壁热缩管性能和用途:

由聚烯烃和热熔胶共挤技术复合而成,广泛用于船用电缆、汽车电线、线束、金属管的防水防潮,及绝缘和密封保护.

收缩温度:80℃-125℃

工作温度:-45℃–+125℃

材料:符合Sony-SS-00259,RoHS, vw-1 600V

标准颜色:黑

特殊颜色:红、蓝、白、黄、透明(非阻燃)

3倍阻燃双壁热缩管的技术参数:

CZY-DWT是一种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、坚实。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、汽车油管、高级线束等。

CZY-DWT is manufactured by co-extrusion of irradiated crosslinking polyolefin and specifically designed hot melt adhesive. This tubing maybe used in a wide variety of electrical applications, including back end connector sealing , breakouts, and connector to cable transitions. High expansion ratio makes it possible to repair most damaged cable jackets without removing connectors.
