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
- Hoop stress performance
- Environmental stress crack resistance combined with long-term hydrostatic strength
- Taste & odor (haptics) performance
- Long-term & accelerated testing data for in-use confidence
- A toolbox approach, with a portfolio that includes PE-RT + adhesive technology for multi-layer applications as well as sealants that can prevent leaks
We have thermoplastic, raised-temperature 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:
- In 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
- In 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
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.
Dow’s Raised Temperature PE resins give you options to turn up the heat in homes and to stay ahead of the competition.
Connector pipes for radiators
Staying flexible in the heat – or cool – of the moment is our specialty, with resins that perform at a range of extremes.
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 sustainable development that is as environmentally friendly as it is structurally and functionally robust.
