PE Adhesive Tape

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
