Celanese - The chemistry inside innovation^™

Hostaform^®/Celcon^® acetal copolymer (POM) possesses a linear structure with a highly crystalline quality that provides a variety of characteristics: outstanding wear, long-term fatigue, toughness and creep resistance as well as excellent resistance to moisture, solvents and strong alkalis.

Its chemical structure provides a higher stability to thermal and oxidative degradation compared to acetal homopolymers.
