Polyoxymethylene, or acetal, is an engineering thermoplastic produced by the reaction if trioxane and a second comonomer. Acetal resins are known for their outstanding balance of properties, offering high stiffness, high mechanical strength, good dimensional stability, high fatigue strength, good creep resistance, good friction and wear characteristics, good chemical resistance and easy processability. Acetal is available in a wide range of product types including unfilled, glass reinforced, mineral reinforced, impact modified, low wear, anti-static, and UV resistant. Acetal polymers are commonly used in engineering applications such as gears, washers, clips, conveyor links, drapery components as well as irrigation and plumbing components.
