Delrin® 150SA – Homopolymer

Acetal Materials

Acetal Copolymer / Dupont Delrin® 150SA Homopolymer


Which Acetal material should you use? (POM)Large Copolymer Acetal Rod

  • Both Acetal Copolymer and Delrin® 150SA Homopolymer are FDA Compliant
  • Both are very stiff and have excellent dimensional stability
  • Are Self Lubricating, Abrasion Resistance, and Excellent Wear properties
  • Available in Natural, Black and Blue. Custom colors also available.
  • Cuts extremely well with standard cutting tools
  • Delrin® AF (PTFE Filled), Glass Filled, and Specialty Grades Available
  • Delrin® 150SA Homopolymer have similar properties and frequently replaces: Noryl®Nylon®, and PET or PBT materials
  • Acetal and Delrin® are very popular High Tech Performance Plastics

Some reasons to choose Homopolymer vs. Copolymer

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.

Why you should use Acetal/ Delrin®

  • Both the Dupont Delrin® and Acetal Copolymer are FDA Compliant
  • They are very stiff and have excellent dimensional stability
  • Are self-lubricating, abrasion-resistant, and have excellent wear properties
  • Cuts extremely well with standard cutting tools
  • Delrin® AF (PTFE Filled), Glass Filled and Specialty Grades Available
  • Delrin® Rod and Plate have similar properties and frequently replace: Noryl®, Nylon and PET materials

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.

Why You Should Use Homopolymer Acetal or Acetal Copolymer Rod

Why You Should Use Homopolymer Acetal or Acetal Copolymer Rod

Delrin® Homopolymer Acetal compared with Acetal Copolymer

Many of our clients assume that Delrin® rod and Acetal rod are the same thing. This is not true.

Yes, all Dupont Delrin® rod is Homopolymer Acetal rod, but not all Acetal rod is Delrin® rod. Dupont is the maker of Dupont Delrin® resins

Delrin® is the trade name for Homopolymer Acetal made by Dupont. Dupont™ Delrin ® is a popular acetal homopolymer brand name and the most commonly used acetal homopolymer.

This is the most recognized of all trade names for Acetal materials, but not the only available Acetal material.
The Copolymer Acetal resin is produced by a wide variety of large plastic manufacturers, BASF is probably one of the largest and most well known. Some main resin names are: BASF Ultraform® H4320, Kepital® F10-02, Hostaform® M25 and many others.

While Delrin® Homopolymer Acetal is a wonderful material, in a larger cross sections Homopolymer can exhibit center line porosity, or ‘soft centers’. This can sometimes be seen with the naked eye, and is a darker white in a normally milky white natural colored material. This center line porosity can cause problems in some applications. This porosity can cause leakage of fluid if under pressure, or soft center’s of homopolymer rod and sheet.

This should not stop you from considering Delrin® Homopolymer Acetal though. Many other properties of the homopolymer resins are superior to the copolymer resins. These properties are:

Some key properties for homopolymer acetal are: higher tensile strength, increased Izod impact, higher deflection temperatures and it is slightly harder. The co-efficient of thermal expansion is a bit higher, and needs to be considered when designing a new part. Extruded Delrin® brand homopolymer resin material also comes in several resin variations, including: Delrin® 150 and Delrin® 507, contact us for details. Dupont™ Delrin® is a popular acetal homopolymer brand name and the most commonly used acetal homopolymer.

Many of our clients prefer the homopolymer rod and sheet for small machined parts. This is due to the increase in a few key properties, and of course brand recognition. Some of our major brand names for quality Copolymer Acetal (POM-C) sheet and Rod include: Tecaform AH®, Sustarin C®, ZL 900® and Pomalux®.

Both resins meet the standard ASTM-D-6778, and the cancelled specs, L-P-395 and ASTM-D-4181. Contact us for certification and specifications you may require.Comparing Dupont Delrin to Acetal Copolymer

The Acetal family of plastic resins are excellent for wear resistance, great mechanical strength, and superior machining properties. It is available in a huge range of sizes and shapes. Click here for more details on Acetal – Homopolymer Acetal Rod, and sometimes referred to as plastic dowel. We also have the capacity to supply colored Acetal Copolymer or Delrin® Homopolymer Acetal rod; click here from more details on the colored Acetal material.

Similar materials to Acetal Copolymer – Homopolymer Acetal are Nylon Rod, PET Rod and Noryl® Rod. Most materials are available as round rod, square rod, bar, strip, sheet and plate.
