Among all thermoplastics, polyacetal sheets, plates, and rods are among the strongest and stiffest. High resistance to solvents and chemicals, low moisture sensitivity, and good fatigue life are all characteristics of polyacetal and Delrin plastic materials. Products made of polyacetal also have outstanding electrical characteristics. There are homo-polymer and copolymer grades of polyacetal available, as well as a material with improved bearing grade.
A semi-crystalline engineering plastic called polyacetal (POM) is useful for engineering applications and is suitable for CNC machining.
