Product introduction:
Cold wrap pipe tape is at room temperature, winding along the wrapped object construction, without the need for heat pipe retrieval, it is also called the tapes. Products made of polyethylene film, a layer of thermal compound to body with butyl rubber adhesive layer were extruded into a band of anti-corrosion materials, the tape for external coating of steel pipes material widely used in the field of pipeline corrosion, also commonly referred to as pipe cold tape, corrosion-resistant cold cold wrap hose, pipe tape, polyethylene tape.
   
Product applications:
Cold tape is widely used in petroleum, chemical industry, city gas, natural gas, electricity and drainage and sewage industries such as steel pipelines corrosion protection and drainage pipe straight pipe, elbow, storage tanks, fittings and other parts of the corrosion protection and restoration.

Note:
1) adhesive tape thickness tolerance for tape thickness ± 5%.
2) heat aging test is under the condition of sample at 100 ℃, 2400h after heat aging, measurement of basement membrane tensile strength, basal lamina fracture elongation, the rate of change of peeling strength.
3) UV resistant aging index refers to the testing of tensile strength and elongation retention。
