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.
