从China供应商批量进口Polyethylene 3ply Tape

Polyethylene 3ply tape is cold applied tape coating system for corrosion protection of oil, gas, petrochemical, and waste water underground or overhead pipelines. It is a three-ply cold applied tape with stabilised polyethylene bcking and butyl rubber adhesive layers on both sides.It is also used as inner-layer tape. It shall be applied by hand or with a wrapping machine Features: Excellent bonding between adhesive and carrier film via co-extruded intermediate layer. Mechanically highly resistant tape system. Practically impermeable to water vapour and oxygen. Resistant to soil bacterial and soil electrolyte. Compatible with coating from PE, PP, FBE, PU, CTe and bitumen and EXT A total coating system with: High adhesion and shear resistance Resistance to corrosion disbondment High electrical resistance High dielectric strength High corrosion protection for steel substrates Iii technical datas Properties UnitT 480T 4100Test method Color carrie film Adhesive inner layer Adhesive outer layer--Black(grey/green) Black BlackBlack(grey/green) Black Blac-- Thickness carrie film Internal adhesive External ahesiveMm Mm Mm0.3 0.34 0.160.3 0.45 0.25Astm d 1000 Tensile strengthN/cm6770Astmd1000 Elongation at break%450500Astmd1000 Peel strength to pipe surface at 23 At 50N/cm 18 1.3 20 1.5En 12068 Annex c Peel strength tape to tape at 23 at 50N/cm 25 3.5 30 4.0En 12068 Annex b Dielectric strengthKv/mm3233.8Astmd149 Insulation resistanceOhm.M÷10121012En 12068 Water vapor transmissionG/ m2 /24h0.10.1Astm e 96 Brittleness temperature-464-464Din53372 Water absorption%0.1 max0.1 maxAstm d 570 Impact resistance at 23¡æJ1818En 12068 Cathodic disbandment at 23¡æc At 50¡æcMm15 3015 30 En 12068 Lap shear strength at 50N/mm20.050.05En 12068.
