Acetal Materials

Acetal Copolymer / Dupont Delrin® 150SA Homopolymer

Which Acetal material should you use? (POM)

  • 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 replace: Noryl®Nylon®, and PET or PBT materials
  • Acetal and Delrin® are High Tech Performance Plastics

Some reasons to choose Homopolymer vs. Copolymer

Both Acetal (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. This excellent mechanical plastic material is also referred to as: Acetal Copolymer rod, Copolymer Acetal rod, Copolymer Plastic Rod, Acetal Copolymer vs Acetal Homopolymer, Homopolymer Acetal rod, Acetal Homopolymer rod, and many others.

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.

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.

  • Excellent Machining
  • Low co-efficient of Friction
  • Very low moisture resistance

PLASTICS IN THE MEDICAL FIELD Cheap Disposable Polyethylene Bags

When we think of plastic, we think of plastic bags you get at the grocery store or maybe your child’s toy that’s made out of cheap throw away material. If you stop and think about it, plastic is everywhere and it’s uses are almost infinite. Take Acetal Copolymer, it is a plastic that replaces metal in numerous applications and is used to make gears, screws and other hard working parts. Consider PTFE for instance which is used to coat your frying pan to make it non-stick, make steam valves and fittings, and chemical resistant parts. Another material is Polycarbonate or Lexan® (a SABIC brand name -formerly G.E. Plastics) which is used to replace glass because it is shatter resistant and is also used for bullet resistant glazing and riot shields. Even the cup of coffee you grab for every morning is made of foamed Styrene – Styrofoam. But plastic has shaped our lives in countless ways, many of them you might not even think of or notice.

Plastics play a big part in the world of medicine. Some other advancements in the area of medicine include assisting people with debilitating injuries and serious afflictions, helping them feel more comfortable and move easier. Prosthetic limbs and joint replacements have come along way since the old days of metal and wood. Since the late 90’s UHMW or (Ultra High Molecular Weight Polyethylene) has become the standard in hip and joint replacements. With plastics like UHMW, which has great wear resistance, excellent strength and very low co-efficient of friction (very slippery), it has made people who need these surgeries have better mobility and better quality of life. These plastics also make prosthetic limbs lighter and stronger for athletes who wish to compete and lead near normal active lifestyles due to the use of plastic polymers (derived from the Greek meaning ‘many parts’) mimicking human flexibility. Prosthetic devices date all the way back to the ancient Egyptians where they used leather and wood for toe and foot replacements. But thanks to today’s technologies and advancements in as plastic, most amputees and athletes can regain their quality of life and enabling them to do what they love.

What has Medical Plastic Done For You Lately?

Another plastic material that has changed the medical field is PEEK (Polyetheretherketone). This material is a newer plastic which has high chemical resistance along with excellent high continuous temperature resistance of up to 480 degrees fahrenheit. PEEK has replaced many metal devices in the medical field, because PEEK is one of the only thermoplastics (plastic which can be bent or shaped) able to withstand high doses of radiation over an extended lifetime. In addition PEEK is used to help many people awaiting kidney transplants because it is used to make a critical component in dialysis machines. These machines need to clean the blood over a period of several hours and because of this, PEEK is the natural solution, as it can be steam cleaned time and time again with little effect on the material. Along with its great chemical, temperature, and fluid handling stability, PEEK is USP Class VI, making it ideal for these types of medical applications. The natural color of PEEK is a beige to tan and is available in sheet and rod. One of the largest manufacturers of PEEK resin is Victrex and their 450G resin.Performance plastics used in Medical applications

Plastics In Medicine – Everyday

Plastic materials have become apart of our lives and has changed the way we take care of the sick and injured, how we protect our foods from germs, and prolong the storage of foods. Plastics protect medical instruments and insure they are sterile. It has made people’s lives better in both the short and long term. It has helped reduce pain, gain better movement and has given people their confidence back. The values of plastic can not be understated and in the future, hopefully plastics will save or prolong many more lives through advancements in technology and the limitless possibilities it presents.
