Omnia Plastica Akulon® POM h Acetal Homopolymer
Categories:	Polymer; Thermoplastic; Acetal (Polyoxymethylene, POM); Acetal Homopolymer, Unreinforced
Material Notes:	The general features of homopolymer acetalic resin are similar to those of copolymer POM c, except that service temperature (under load) is slightly higher but resistance to hydrolysis and strong alkali is lower. Features: High fatigue resistance. Good dimensional stability. Low friction coefficient High compressive strength. The shock resistance is good even at low temperature. Excellent machinability, especially on automatic equipment Colour: natural Weak Point: Compared to PA6 it has lower abrasion resistance, particularly in dirty and dusty environments. Compared to POM c. its resistance to hydrolysis is lower. Application: Mechanical: it is used for mechanical applications such as bearings, cams, gears with low torque, gear wheels, conveyor rollers and dimensionally stable precision parts. Food contact: being physiologically inert, it is suitable for food contact. It can be used in water at 80° C. Electrical: as it is not hygroscopic, it is commonly used for electric components such as insulators. Chemical: it is resistant to alkali and organic compounds. Thanks to its good chemical properties it is suitable for pump components, flanges and components for chemical plants.
