1.Use polyethylene and butyl rubber as main materials,excellent insulation resistance and Iow water absorptivity.
2.Wide range of operation temperature from-30oC to 80oC.
3.Ideal tape anti-corrosion system is a multi-layer system which is composed of inner anti-corrosion tape and outer protective tape resistant to outside mechanic impact. With high anti-corrosion perf ormance and impact resistance.
4 .With a long life of over 30years.
5.Widely used on pipes whose sleeve diameters are from 50mm to 1800mm.Convenient construction, safe and clean operation,suitable to factory production and field construction under normaltemperatures.
6.Low cost.


Protective tape (outer tape)
Polyethene is used as the base material which is coated by the liquid butyl rubber film, both of which are pressed and compounded. The film of protective tape is thicker and higher in intensity. Protective tape will protect the pipe and its anti-corrosion tape surface from damages.
