What Does The 3LPP Pipeline Layer Contain?

´The first layer of 3LPP is a fusion-bonded epoxy powder, which offers strong adhesion, corrosion resistance, and chemical resistance.
The second layer is a polymer adhesive, typically a maleic anhydride-grafted copolymer. This serves as the middle layer, bridging the gap between the rigidity of FBE and the flexibility of PP.
The third layer is polypropylene, either a copolymer or homopolymer. It serves as the outermost layer, protecting the inner layers from mechanical damage, offering high-temperature and weather resistance, and preventing moisture penetration.
