4:1-Black Heavy Wall Tubing (HDT-A)

4:1-Black Heavy Wall Tubing (HDT-A)

HDT-A is thick wall polyolefin tubing. The toughness and weather ability of the tubing make it well suited for exposed applications. HDT-AN is supplied with a specially designed hot melt adhesive layer. The adhesive is applied during extrusion of the tubing thus achieving a very smooth, constant adhesive layer, which ensures excellent sealing properties. RoSH compliant and halogen free.
