Acetal Screws, Hex Nuts, Set Screws, Threaded Rod and Custom Parts

Polyoxymethlene
Acetal is an engineering thermoplastic. It is also known as polyoxymethlene or POM. POM is used in precision parts that require high stiffness, low friction and dimensional stability. From -40 degrees C to 80 degrees C POM is known for its high strength, hardness and rigidity. Natural POM is an opaque white material. However, it can easily be dyed to almost any color. It has a high crystalline composition. It is available as a homopolymer and a copolymer. … Read more

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.

Don’t Sweat It! These 4 High Temp Plastics Can Take the Heat

Choosing the Right Plastic for the Job
When choosing a heat resistant plastic, it is important to pick the best material for the job. Costly damages can then be avoided. More and more, these high temperature plastics are taking the stage because they are light, versatile alternatives to metal, ceramics and older-generation polymers.
Operating Temperatures
Some plastics have permanent operating temperatures of more than 150° C and often use special reinforcing materials, … Read more
