DELRIN, a brand name for polyoxymethylene (POM-H), is a durable and strong engineering thermoplastic that is often used as a replacement for metal. It is known for its high tensile strength, low friction, excellent wear resistance, and dimensional stability, making it ideal for high-precision parts.  DELRIN is commonly used for applications in food processing, automotive, and medical fields.  We find DELRIN to be superior to other plastics, resins, or acrylics used in our industry.
