Our PP70 tape
1.New type mesh reinforced fiber, designed for external anticorrosion of embedded steel piping-strongest anticorrosion nature, best anti-earth stress capacity.
2.Strict quality control-ISO9001
3.Reinforced mesh fiber PE as base, paving one layer of improved asphalt with high viscosity--enhance the tension intensity several times than that of traditional adhesive tape.
4.Reduce deform due to change of temperature, resist external impact,protect cathode.
5.Higher than the data in SY/T 0414-2007 Standard.
6.More bonding force, more elasticity, aging resistance.
7.No solidification, no hardening, automatic restore closing after
being damaged----suitable for thermal expansion and contraction
8.Improved adhesive layer---avoid traditional hollow.
9.Easily and effective application.
10.Environment protection---no toxic , no harmful
11.Combined with many materials
12.Thickness--1.1-1.8mm
