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
Delrin® homopolymer is used to make screws, hex nuts, threaded rod, set screws, as well as many other fasteners and custom parts. Delrin® is a crystalline plastic that offers an excellent balance of properties between metals and plastics. It is also known as polyoxymethylene or POM. It is produced by different chemical companies with slightly different formulas and sold by a variety of names such as Delrin® and Celcon® . … Read more
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
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.

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.
Some plastics have permanent operating temperatures of more than 150° C and often use special reinforcing materials, … Read more
