DWHF Heat Shrink Tubing : Reliable and Versatile
The new DWHF heat shrink tubing is a dual wall tube with a flame retardant and halogen free jacket, in line with the highest requirements of the rail industry, EN45545 standard (high level of flame retardancy, low level of toxicity, smoke, in a fire situation). The inner adhesive layer will melt during installation and create a seal, with the underlying substrate preventing ingress of moisture, corrosion, and connectivity issues.
Overview
Part of the Raychem tubing product portfolio, the new DWHF heat shrink tubing is a dual wall tube with a flame retardant and halogen free jacket, inline with the high requirements of the rail industry EN45545 standard (highlevel of flame retardancy, low level of toxicity, smoke, in a fire situation).
