热缩管

LTS-DWT双壁内胶热收缩套管

LTS-DWT Heat-shrinkable tube with inner adhesive

材料：外层：交联改聚烯烃树脂

            内层：热熔性粘接剂

收缩倍率：2:1 3:1 4:1

特点:

柔软，阻燃，环保；

优异的防水，防潮性能；

最低完全收缩温度：125℃

满足UL224标准，并能通过VW-1阻燃等级，认证号：E351797。

应用领域：

            适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、船舶、高级线束等。


Material：Out layer：Cross-linking modified polyolefin

            Liner：Hot-melt adhesive

Shrink ratio： 2:1 3:1 4:1

Characteristics:

Flexible, Halogen-free, RoHS compliant.

Water proof and moisture proof.

Minimum full recovery temperature:125℃

UL224 VW-1，File No.E351797

Application:

            Widely used to electrical applications, including back end connector sealing,breakouts, and connector to cable transitions. This tubing maybe used to protect auto wires, shipping cable, bundle wires and metal tubes against water and moisture. High expansion ratio makes it possible to repair most damaged cable jackets without removing connectors.
