PVC-UH high-performance rigid polyvinyl chloride drainage pipes are made primarily from polyvinyl chloride, with necessary additives, and are formed through extrusion processing. As a new and innovative drainage pipe material, it enhances the mechanical properties of the product and improves the pipe connection method over traditional PVC-U and PVC-M pipes. The PVC-UH drainage pipes boast superior pressure resistance, impact resistance, and tensile properties, as well as acid and alkali resistance, light weight, and a long service life.
