Cold-Applied Pe Pipewrap Tape

Detailed Selling Lead Description
cold-applied PE pipewrap tape
1. Product profile
The compound cold-applied PE pipewrap tape uses variety of PE and EVA as base film and butyl rubber as the coating. It is compounded one time under hot-melt status. In terms of use, the product may fall into three kinds, namely, anticorrosive adhesive tape (internal tape), protective adhesive tape (external tape )and repair tape .

2. Function characteristic
This product is characterized by uniform releasing force, excellent anticorrosive and insulation performance, long aging resistance time and ultraviolet rays-proof.
3. Apply range
It is widely applied to pipes of petroleum, natural gas, chemical industry, electricity, urban fuel and drainage.
