Heat-shrinkable Material for Thermal Insulation Pipeline

RSPBJ series heat-shrinkable tape is the special material for heat-shrinkable tape type joint of prefabricated direct buried insulation pipe. The outer layer is radiation cross-linked polyethylene substrate, and the inner layer is coated with hot melt adhesive.

During installation, the outer substrate is heated to contract radially and the inner hot melt adhesive melts. The hot melt adhesive forms a good bond with the HDPE outer sheath and sleeve tube, thus forming a joint structure form consisting of the outer sheath, sleeve, heat shrinkable tape and insulation layer.

Features:Fiber reinforced substrate, Resistant to soil stress, high temperature thermal stress, tensile shear, good sealing, Resistant to heat aging, chemical media corrosion.
