Main materials of hot melt pipe fittings

The main materials are polyethylene (PE) or polypropylene (PP). These two plastics possess excellent corrosion resistance, pressure resistance, and high-temperature resistance, meeting the requirements for transporting various liquids. During production, polyethylene or polypropylene granules are melted at high temperatures and then processed into pipes using a special technique. This processing method results in very strong weld points and excellent connections, ensuring the safety and reliability of the pipeline system.

Besides polyethylene and polypropylene, hot-melt pipes can also be made from other plastic materials, such as ABS and PVC. These materials each have their own characteristics and are suitable for different occasions and applications. For example, ABS plastic has good corrosion resistance and anti-aging properties, making it suitable for transporting corrosive liquids such as acids and alkalis; PVC plastic has good mechanical and electrical properties, making it suitable for protecting pipes containing wires and cables.
