Delrin, the ultra-durable engineering plastic
About Delrin
Delrin, also known as POM (polyoxymethylene), is a technical plastic highly valued for its high rigidity, wear resistance, and excellent friction coefficient. Designed to offer superior mechanical properties, it is often compared to metals due to its robustness and durability. Delrin is particularly favored in the manufacturing, aerospace, and automotive industries for designing precise and resilient parts.
