UPVC Pipes and HDPE Pipes
Material Overview
1. UPVC (Unplasticized Polyvinyl Chloride)
Definition: Rigid PVC without plasticizers, offering high chemical resistance and dimensional stability.
Key Trait: Lightweight, non-conductive, and suitable for pressurized systems.
2. HDPE (High-Density Polyethylene)
Definition: Flexible thermoplastic with high impact resistance, made from petroleum-based ethylene.
Key Trait: Superior fatigue resistance and leak-free jointing via fusion welding.
