Plastic Acetal Round Bar 4" diameter Retail Price

About Acetal|Acetal copolymer (POM-C). A crystalline engineering plastic with excellent dimensional stability, low moisture absorption, low friction, and good machinability. The most commonly machined engineering plastic alongside nylon. Machines beautifully at high speeds with sharp tools: clean chips, excellent surface finish, and tight tolerances achievable. Used for gears, bushings, bearings, valve components, and food processing equipment. Compare to Delrin (acetal homopolymer, slightly stronger and stiffer) and Nylon (absorbs moisture, slightly tougher).
