PE Adhesive Tape
3 Ply double-side adhesive tape
3 Ply mastic corrosion protection tape is designed for high corrosive andmechanical stress. The PE adhesivetape complies with DIN 30672 and DIN EN 12068 for buried andimmersed pipelines, it has a stabilized polyethylene carrier film coated onboth sides with a permanent plastic and a butyl rubber based syntheticcompound.
The PE adhesive tapefrom XUNDA T400 series is a cold applied tape coating system to protect oil,gas, petrochemical and waste water underground or overhead pipelines fromcorrosion. The PE adhesive tape is a three-ply coldapplied tape with stabilized polyethylene backing and butyl rubber adhesivelayers on both sides. It is also used as inner-layer tape. It shall be appliedby hand or with a wrapping machine
Features of the PE Adhesive Tape
1. Excellent bonding between adhesive and carrier filmvia co-extruded intermediate layer.
2. Mechanically highly resistant tape system.
3. Practically impermeable to water vapour and oxygen.
4. The PEadhesive tape is resistant to soil bacterial and soilelectrolyte.
5. Compatible with coating from PE, PP, FBE, PU, CTE andBitumen.
6. High adhesion and shear resistance
7. The PEadhesive tape is resistance to corrosion detachment
8. High electrical resistance
9. The PEadhesive tape has high dielectric strength
10. High corrosion protection for steel substrates
