3LPP is similar with 3LPE coating system, the difference is instead of using Polyethylene as an outer layer, 3LPP uses Polypropylene tape. 3LPP is provide for improved impact and abrasion resistance compared to 3LPE and is suitable with operation temperatures of more then 110º C. 3LPP consisting of a inner layer of Fusion Bonded Epoxy, copolymer adhesive layer and outer layer of Polyethylene. Inner layer provide corrosion protection and flexibility while outer layer of Polyethylene provide impact and abrasion protection. Between the inner and outer layer are tape.
The total thickness and combination of various layers used will be in accordance to user’s specification.
