Polyacetal, also known as polyoxymethylene (POM), is a versatile and widely used engineering thermoplastic. It is a type of polymer that belongs to the family of polyoxymethylenes, which are characterized by their excellent mechanical properties, dimensional stability, and resistance to chemicals and moisture. Polyacetal is commonly used in various industries due to its unique combination of properties and ease of processing.
Polyacetal (POM) sheets and rods are among the strongest and stiffest of all
thermoplastics. Plastic materials are characterized by good fatigue life, low moisture
sensitivity, and high resistance to solvents and chemicals. Polyacetal products also
contain good electrical properties. Homo-polymer and Copolymer grade of Polyacetal
are available including an enhanced bearing grade material.
Polyacetal -POM is a semi crystalline engineering plastic that is beneficial to
engineering applications, and is suited to CNC machining.
