ACETYL (POM)

Acetyl was discovered and developed by two independent research groups in the mid-20th century:

DuPont: In the 1950s, DuPont chemists led by Dr. Eugene Rochow developed the first practical method for synthesizing polyoxymethylene. This marked the beginning of commercial production of acetal resins under the trade name “Delrin®.”

Celanese Corporation: Around the same time, a team of researchers at the Celanese Corporation (now part of Celanese) also developed their own method for producing acetal resins.

Pictured above are many valve components, as well as moving parts for barriers due to the low friction required for the applications. Several components also have steel or brass inserts insert moulded into them, as well as some with secondary operations like assembly and spin-welding. 

Why choose Acetyl for your injection moulding project?

  • 1. High strength and stiffness: Acetyl, also known as Polyoxymethylene (POM), has a high strength-to-weight ratio which makes it ideal for producing strong, stiff parts.
  • 2. Dimensional stability: Acetyl has excellent dimensional stability, which means that the parts produced through injection moulding will retain their shape and size, even under varying environmental conditions.
  • 3. Good wear resistance: Acetyl has good wear resistance properties, which makes it an excellent choice for producing parts that are subjected to repeated frictional forces.
  • 4. Chemical resistance: Acetyl has good chemical resistance, making it an ideal choice for producing parts that are exposed to harsh chemicals.
  • 5. Low moisture absorption: Acetyl has low moisture absorption properties which makes it suitable for use in applications that require a high degree of precision and accuracy.
  • 6. Ease of processing: Acetyl is easy to process, which makes it ideal for injection moulding.
  • 7. Low coefficient of friction: Acetyl has a low coefficient of friction, which makes it suitable for producing parts that require low frictional forces.

Overall, moulding in acetyl offers several advantages, making it an excellent choice for producing high-quality plastic parts.
