Product Description

Product Introduction

 

Definition & Rationale
 1.Heat shrink tape is a type of ribbon material that shrinks when heated. It is mainly made of polymer materials such as polyolefins. Its working principle is to use the memory effect of the material, during the production process the material is stretched into a certain shape, when stimulated by external heat, the molecular chain will move, so that the material is restored to its initial state, so that it is tightly wrapped on the surface of the protected object. 

Features:
1.Good sealing
2.Excellent anti-corrosion properties
3.Mechanical protection
4.Good weather resistance

   

Product Applications
1.It is mainly used for wrapping around pipe, anti-corrosion of kinds of pipe joints, and repairing pipes.
For example: Oil and gas pipe, PU insulation pipe, 3PE/2PE steel pipe.
2.Power industry
