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.…
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.…
