Polyacetal is used in many static and dynamic industrial applications replacing materials like; steelbrass, bronze, copper and aluminum. Polyacetal have improved part life because of; better wearmore chemical and corrosion resistance. These materials reduce factory noise and will reduce oreliminate the need for lubricants.
