Acetal (POM): Ultraform®
A line of acetal polyoxymethylene (POM) copolymer products under the tradename Ultraform® are available from BASF. The Ultraform acetal product range comprises versatile engineering plastics having varied properties designed for use in exacting components capable of withstanding high stresses. The Ultraform acetal grades fulfill the demands imposed on an engineering material in especially high measure. They combine high rigidity with mechanical strength and afford good elastic properties, high toughness, dimensional stability and excellent sliding friction properties.
Special mention should be made of the chemical resistance of Ultraform® acetal, particularly with respect to conventional grades of gasoline (even those containing methanol and ethanol) as well as to diesel fuels (also biodiesel).
