Both POM grades have very similar properties. Our clients seem to prefer the Dupont brand name Homopolymer materials because of the superior physical properties. The issues that lead clients to the Copolymer is a slightly lower cost, and the minor inherent center-line porosity in the Delrin® 150SA Homopolymer grade.
Dupont™ Delrin ® is a popular acetal homopolymer brand name and the most commonly used acetal homopolymer.
The Delrin® 150SA is a brand name of Dupont, and it is often referred to as POM-H or Acetal Homopolymer. Common brand or trade names for extruded Acetal sheet and rod materials include: Tecaform® AH, SUSTARIN® C, ZL® 900-C, Pomalux®, Unital®, Mechatec Acetal®, Acetron® and many more.

Some reasons to choose Homopolymer vs. Copolymer
Both POM grades have very similar properties. Our clients seem to prefer the Acetal over the Homopolymer materials due to the inherent center-line porosity in the Delrin® Homo-polymer version. This means, that along the center of a rod, or the middle of a sheet, there is a band of area with tiny porous holes. This can weaken or cause problems with a finished part, and in extreme cases, you may see blow by or leakage at this center line. While Delrin® is a brand name, it is a POM Homo-polymer.
The most requested and popular item we supply is the Acetal; the POM Copolymer resin made by one of the other big resin manufacturers – like BASF or Celanese/Tacona.
Both Delrin and Acetal are ITAR compliant, and Delrin and Acetal are RoHS compliant.
The most requested and popular item we supply is the Acetal; the POM Co-polymer resin made by one of the other big resin manufacturers – like BASF or Celanese/Tacona.

Acetal materials are excellent machining materials – a favorite of machinists. Works like a soft brass, and has exceptional dimensional stability. It comes as a stress relieved material, however if you plan to do extensive machining, you may need to stress relieve the parts prior to final pass. Rods are machined well in lathe and mill, sheets are machined or cut in most common machine tools.

Is colored Acetal Copolymer – Delrin® Homopolymer Rod Readily Available?
We get this question frequently.
The easy answer is yes, however, the most common available colors are Black and Natural (white in color). But to continue the thought, we have several manufacturers that run ‘Medical’ grades of Acetal Copolymer as well as Acetal Homopolymer (ie: Dupont Delrin® 150SA Homopolymer Acetal) in several colors. These materials are special run, but can frequently purchase by the standard length without a custom run. The biggest factor may be the price. The colored version of Acetal Copolymer – Delrin Homopolymer Acetal materials are dramatically more expensive.
Colored Acetal Copolymer – Dupont Delrin® Homopolymer 150SA Rod
While price is a factor, the benefits may out weigh the cost. Many of our clients use these colored rods to help differentiate their product from their competition. With colors that can come close to a logo color or match a machine, these advantages are clearly visible. Having a special color available to machine small to medium runs of your product can save you thousands over molding a new part for trials.
What colors can I get in Acetal Copolymer or Dupont Delrin® 150SA Homopolymer Acetal Rod?The range is a bit limited, but does include: brown, dark blue, dark green, gray, light blue, light green, red, rust and yellow (and of course Natural and Black). For details on the properties of these materials click here: Acetal Copolymer and Dupont Delrin® 150SA Homopolymer Acetal.Dupont™ Delrin® is a popular acetal homopolymer brand name and the most commonly used acetal homopolymer.
