The impact resistant (PVC-M) pipes and fittings for water supply are a new type of plastic pipes and fittings with high toughness, which are mainly made of polyvinyl chloride resin as the main raw material and physically modified by adding composite impact modifiers. They are extruded or injected.
The effective addition of composite impact modifiers increases the ductility of the product while maintaining the high strength of PVC-U pipes. It also has the advantages of simple PVC-U pipe connection, straightness, and high impact resistance of PE pipes, making it a new type of plastic pipe fittings with excellent comprehensive performance.
This product is suitable for transporting domestic drinking water and general purpose water under pressure, especially in the low-temperature field, which can better demonstrate its performance advantages.
