1.Introduce
WSS series of 3PE heat shrinkable wraparound sleeves(www.heatshrinkfactory.com) are 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.
