Hostaform® Acetal Copolymer (POM) - High Strength and Chemical Resistance

Hostaform® acetal copolymer (POM), supplied by Celanese®, 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 offers higher stability to thermal and oxidative degradation compared to acetal homopolymers.
