Heating & Plumbing Pipe
Pipe extrusion and materials experience to help maximize performance
Dow’s advanced resin portfolio gives pipe manufacturers a competitive edge with durable, leak-resistant PE plastic pipes that offer the lowest total life cycle cost, as recognized by the Alliance for PE Pipe.
Plastic pipes made from PE excel in small-diameter heating and plumbing applications, from radiator and under-floor heating to plumbing and sanitary systems. Our resins for raised-temperature (RT) plastic pipes offer exceptional processability and long-lasting performance through every temperature cycle, year after year. With a focus on enhancing efficiency, reducing scrap rates, and lowering production costs, our innovative options help pipe producers address industry standards while offering performance benefits such as improved durability, enhanced leak resistance, and sustainable material advantages.
