Delrin Sheet and Delrin Rod
Acetal and Delrin Rod and Sheet
Delrin®, Co-Polymer, Homo-polymer, Celcon®, BASF
All Are P.O.M. (PolyOxyMethylene)Stocked in Sheets, Rods, Tube, Block, Strip and Slab
Acetal and Delrin Rod, Sheet and TubeThis material is used frequently in a self lubricating bearing surface or slide type applications. Extremely low water absorption makes this a perfect material for valves, seats and moving parts in water filled areas (many white valve parts in toilet tanks are made of Acetal). Crisp machining and tight tolerances are easily obtainable with these materials.

“This stuff machines like soft brass!!” – Alex R. “We produce a small medical part, and this material has the best of all the properties we need. It machines well, is very dimensionally stable, and has the agency approvals we need. Thanks for recommending it.” – Glenn P. “Thank you for suggesting Acetal rod for my project, it was great to work with” – Thomas L.Note: The Dupont brand of Acetal is called Delrin®, however we are frequently asked for Delron, Delran, Derlin, Delren, Delrun, Derlin and many more. We will do our best to translate what you ask for into a standard product. Go ahead and call us, we are happy to assist.
