Acetal

Nylon is a synthetic plastic material popular for its toughness, low coefficient of friction, and resistance to abrasion and wear. It is one of the most widely engineered thermoplastics with applications including machining components, fabrics, and moving parts such as wheels and rollers.

Acetal, also known as polyoxymethylene (POM), is a semi-crystalline, engineered thermoplastic used for precision parts that require high stiffness, low surface friction, and good dimensional stability. It is made in several slightly different formulations and sold under various brands.
