polyacetal
Quick Summary
Polyacetal, also known as polyoxymethylene (POM) or acetal, is a type of polyether with a simple structure. It is created through the polymerization of formaldehyde. While pure polyacetal is unstable and breaks down when heated, commercial versions are treated to cap the ends of the polymer chains, making them more stable.1
This engineering plastic is known for its high strength, low friction, and resistance to oils, greases, and solvents. It is often used as a substitute for metal in various parts, including plumbing components, automotive parts, appliance parts, electronics, gears, and zippers.1
