Plastic Materials Close Up: Polyoxymethylene (POM), Acetal, Delrin®, and Celcon®

Polyoxymethylene (POM)
POM is a thermoplastic material also known as acetal. It is a molecule containing the functional group of carbon bonded to two –OR groups. POM was first discovered by German chemist Hermann Staudinger who won the 1953 Nobel Prize in Chemistry. He had studied it in the 1920s but found it to be thermally unstable. DuPont synthesized a version and filed for patent protection of the homopolymer crediting R.N. MacDonald as the inventor. … Read more

Threaded Rod in Plastic: PEEK, Nylon, PTFE, Vinyl Ester, Acetal and Ultem®

What is Plastic Threaded Rod?
Plastic threaded rod, also referred to as a stud, is a bar of round plastic material threaded in a helical structure. It is used to convert between rotational and linear movement or force. Thus, threaded rod creates a strong resistance to pressure and tension. The direction of the rotation the threaded rod creates depends on whether the rod has a right-hand thread or a left hand thread.

PEEK Medical Implants

Medical Implants
PEEK or polyetheretherketone is a high performance, engineered plastic. It is one of the materials of choice for spinal implants as well as trauma fixation. Trauma fixation is the repair of broken bones or any bodily injury that can result from force or violence applied to the human body. It is also used for cardiovascular implants as well as in orthopedic surgery and dentistry. While in the past, metals such as titanium have often been used for these purposes, … Read more
