[0002] PPR (random polypropylene copolymer) pipes are widely used in building water supply and drainage, heating, chemical engineering, and other fields due to their many advantages, including high temperature resistance, high pressure resistance, corrosion resistance, and sanitation and environmental protection. In the production process of PPR pipes, the mixing effect of raw materials plays a vital role in the quality of the pipes. High-quality raw material mixing ensures that the pipes meet ideal standards in terms of physical, chemical, and mechanical properties.
