Why is Delrin a good material for corrosive environments?


Delrin is a thermoplastic that’s one of several formulations of polyoxymethylene. The material was invented in the 1950s, and it’s been used since then in all types ways: everything from yo-yos to guitar picks. The qualities that make Delrin so universal also make it a good fit for oil and gas production, especially severe service. Delrin is tough, and it wears more slowly than other materials when exposed to corrosive materials, such as sour gas and carbon dioxide. It’s also cost effective and cheaper to manufacture than stainless steel. At Kimray, we use Delrin in many products, including our Lever-Operated Control Valves, Low Pressure Control Valves and Treater Valves. Kimray uses Delrin 500P NC010 from DuPont.
