Description
3PE Wraparound heat shrinkable sleeve for joint coating of pipelines
Heat Shrinkable sleeves consist of a radiation cross-linked heat shrinkable backing, coated on the inside with a heat activated adhesive. While the modified polyethylene material of the backing offers superior mechanical protection, the specially formulated adhesive offers excellent corrosion protection under demanding conditions. Used in conjunction with the proprietary epoxy primer, the 3 layer system is the choice of discerning clients who need long term corrosion protection. The system is suitable for most of the common pipeline coatings like PE, PP, FBE etc.
