Domestic Plumbing Pipe

Pipe extrusion and specification expertise to help maximize performance

When it comes to heating and plumbing, reliable performance, durability and trustworthy connections make the difference between a house and a home. We have a resin portfolio that puts pipe manufacturers ahead of the curve – and the competition. According to the Alliance for Polyethylene (PE) Pipe, PE resins offer the lowest total life cycle cost of all municipal pipe materials – and domestic plumbing and heating designers are building on that success.

Plastic pipes made from PE are durable, leak-resistant and offer sustainability benefits over alternatives materials. That is why more pipe producers are choosing plastic pipes, and Dow’s extensive portfolio, to help them meet standards for small-diameter heating and plumbing applications that range from radiator and under-floor heating to plumbing and sanitary systems.

Dow’s portfolio of resins for raised-temperature (RT) plastic pipe connects you with processability and in-use performance – temperature cycle through temperature cycle, year after year. Building upon plastic piping resins that have stood the test of time, Dow continues to innovate to help pipe producers increase processing efficiency, decrease scrap rates, and reduce production costs while offering performance enhancements like: 

Improved flexibility 

High gloss​

Environmental stress crack resistance combined with long-term hydrostatic strength

Taste and odor ​(organoleptices) performance

Long-term and accelerated testing data for in-use confidence

Hoop stress performance

A toolbox approach, with a portfolio that includes PE-RT + adhesive technology for multi-layer applications

Domestic Plumbing Products

Want to dive right into the details? Explore our product catalog. 

We have thermoplastic, raised-temperature resistant PE resins that can help pipe producers meet or exceed key performance standards without crosslinking. Plus, existing crosslinked polyethylene (PEX) pipe equipment can be easily converted to produce pipe from recyclable thermoplastic PE to meet regional requirements, like: 

  • North America 
    • Plastics Pipe Institute (PPI) TR-4 listing of 630 psi HDB at 180°F (82°C) 
    • ASTM F2623 and ISO 10508 (classes 1, 2, 4, and 5) non-potable heating pipe requirements
  • Europe 
    • ISO 9080 for long-term hydrostatic strength 
    • ISO 10508 for hot water applications (all classes)
    • ISO 2578 for prolonged heat exposure 
    • ASTM F2023 and NSF P171 protocols for chlorine resistance

Plumbing applications

If you’re looking for a supplier who has the optimal connections, start here. As in-floor heating systems have advance, Dow provides products that can accommodate those optimized formulations. We understand the complex balance of properties needed to instill confidence and anticipate performance requirements for heating applications.

Raised temperature resistance (PE-RT) resin for more flexible heating pipes

Discover DOWLEX™ 2355 PE-RT Resin and its unique molecular structure with a controlled side chain distribution, which provides excellent stress crack resistance properties combined with outstanding long term hydrostatic strength.  

Clean water is essential to human life. For daily personal use, as well as agriculture, industry, energy production and even recreation. Our goal is to help hot and cold-water plumbing pipe manufacturers meet design and consumer expectations to safely deliver this essential natural resource – every day, without performance issues.

Dow’s materials science expertise spans a wide variety of building and construction markets. From cities to homes and commercial buildings, we offer solutions that help reduce waste, improve efficiency and work toward the goal of development that is as environmentally conscious as it is structurally and functionally robust. 

Dow has decades of experience in the pipe industry and works with leading pipe extruders and specifiers to develop superior pipe products. We operate pipe technology R&D centers around the world and are constantly working to improve resins and develop new materials that help piping systems of all kinds operate at maximum performance.

From mono-layer structures to multi-layer, highly demanding pipe applications, we have base, adhesive and tie-layer/impact modifier resins that can optimize reliable performance and cost-to-produce. Contact us to help with your design, specification or performance challenges.
