Product Structural Features

1. High Crystallinity
Made from a single polypropylene monomer, the molecular chain contains no ethylene monomers; the molecular chain is highly regular and offers a long service life.
2. Excellent Corrosion Resistance
It can withstand corrosion from high-concentration acids and bases within a pH range of 1-14.
3. Heat-Resistant, Insulating, and Energy-Saving
It can operate in temperatures from -20°C to 110°C. Its low thermal conductivity provides excellent insulation performance.
4. Reliable Connection
The hot-melt joints are stronger than the pipe itself, preventing them from breaking due to soil movement or loads.
5. Excellent Construction Performance
This product is lightweight, features a simple welding process, is easy to install, and offers a low overall cost, suitable for complex process piping. PPH piping systems are widely used in industries such as electroplating, etching, chemicals, pharmaceuticals, wastewater treatment, and environmental engineering.
