The Top 3 Plastic Additives for UV Stabilization

Exposure to UV Radiation
Over time, exposure to the UV radiation from sunlight will degrade plastics. Polymer photo-degradation occurs when non-visible UV radiation made up of short wave lengths breaks down the polymer chains in plastics. This is called the photo-degradation process.  It is caused by exposure to UV radiation and results in the deterioration of physical properties such as loss of impact strength, changes in color, cracking,  loss of elongation and tensile strength as well as chalking of the surface. … Read more

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.
