Below is a list of Delrin manufacturers from Caledonia, Michigan. Delrin is actually the trade mark name of a specific acetal polyoxymethylene, an extremely versatile and durable thermoplastic that serves as a direct replacement for metal products in a number of industrial, commercial and residential applications. Abbreviated POM, this plastic material is available in both homopolymer and copolymer products. Although the two differ slightly in chemical and mechanical properties, these engineering thermoplastics exhibit not only high strength, but also excellent dimensional stability and a low coefficient of friction.
