Acetal - Printer Friendly Version

Acetal resins are odorless, tasteless and nontoxic. Key properties include high strength and rigidity, excellent dimensional stability, fatigue endurance, relatively low moisture absorption and low dynamic and static coefficient of friction. Perhaps the most outstanding feature is Acetal's ability to retain these properties over a wide range of adverse conditions including extreme humidity, exposure to solvents and other chemicals and high loading and prolonged cyclic stressing. Acetal is widely used in the automotive, electrical, machinery, equipment and watch making industries.
