Cold polypropylene tapes

? Polypropylene cold tapes? CTB-B tape wrapped around the cold polypropylene fiber reinforced polypropylene pipe corrosion that is cold tapes can be widely used in petroleum, natural gas, chemicals, urban construction, water supply and drainage, gas, gas transmission pipeline steel and steel underground storage tank external corrosion and rehabilitation works. It is a unique polypropylene fiber reinforced backing, high viscosity butyl rubber modified asphalt anticorrosive rubber coating certain thickness, and then covered with a layer of anti-sticking isolation membrane is formed. ??? Advantages 2 construction site is simple, flexible construction methods;? 2 impact resistance, tensile, high bond strength;? 2 anti-aging, UV resistance;? 2 pairs of human non-toxic, harmless. ?? Technical indicators performance test standard tensile strength ≥60MPa GB / T 1040-92 peel strength primed steel> 45N / cm GB / T 2792-98 on tape backing> 25N / cm Dielectric strength ≥25MV / mm GB / T 1408.1-99 volume resistivity ≥1 × 1013W? cm GB / T 1410-89 water vapor permeability (24h) <0.45mg / cm2 heat aging (2400h) <25% GB / T 1040-92 UV-resistant aging (168h) ≥80% EN 12068 Water absorption <0.3% ASTM D570-2005 temperature -5-50 ℃ - Temperature -20-60 ℃ -??
