PE bitumen outer protective tape

1. The least thickness of one layer of PE60 series PE anticorrosion adhesive tape may be to 1.0mm (0.8mm is also available as per user demand). By only one-time winding, national reinforcement class standard may be realized and overlapping area of adhesive tape is 55% to save operation cost.

2. The base material and adhesive layer is quite different essentially from domestically-made cool winding of compound PE. The base material of domestically-made cool winding is blow molded PE, and that of PE60 series is calendared PE. The adhesive tape of former is pressure sensitive tape, but PE60 series is butyl rubber modified asphalt. Since uneven force and different thickness of blow molded PE production procedure, tension strength of adhesive tape is not enough and pressure sensitive layer is thin and bonding is not strong, PE60 anticorrosion adhesive tape is able to make up such defects.

3. The thickness of anticorrosion layer of PE60 is uniform with stable corrosion resistance nature, not to be impacted by acid, alkali and salt in the soil.

4. The operation of PE60 is simple and after winding, backfilling may start immediately. Hence there is no pollution and operators are protected.

5. PE60 is tough without aging and hardening to prevent from damage of earth stress and automatic closing is available even after being damaged.

6. PE60 is provided with good resistance against water and vapor, its strong adhesiveness is able to be against invasion of air and moisture.

7. The adhesive layer is provided with excellent viscosity and elasticity, able to be applied against expansion and shrinkage without peeling from piping to realize complete bonding with weld, no hollow valley that happens often at other kinds of anticorrosion material exists.

8. PE60 is provided with excellent performance, well-developed production procedure, low cost of material and construction; it is widely used in many industries such as petroleum, natural gas, petrochemical, fuel, thermal power, municipal work, power, water supply, metallurgy and vessel building.

PE60 has different thickness and width to offer for selection of user based on design and construction requirements and it is designed to be good for 50 years.
