Heat shrinkable material also called Polymer shape memory material, it is a combined material by combing polymer material and radiate processing technqiue. Normal polymer material like PE, PVC etc usually is liner structure, after electric radiating it will become net structure, these material will have memory effect, after extending and cooling forming this material can retain its former shape.
We make this material which can wrap pipes or other material to produce the effect of insulation, anti-damp, sealing, protection, connecting etc, the shrink ratio can reach 50% to 80%
