| TECAFORM® FG Blue is Ensinger’s new blue colored acetal designed specifically for the food industry. TECAFORM® is resistant to hot water, and typical cleaning chemicals, and it possesses good bearing and wear properties. Its blue color makes it more visible than standard grades. TECAFORM® is commonly used as bushings, rollers, wear strips and other applications requiring a combination of strength, low moisture absorption, chemical resistance and dimensional stability. TECAFORM® is used in a wide variety of food industry applications requiring good strength and toughness, dimensional stability, wear resistance and the ability to operate in a wet environment with little absorption. Material handling, filling and bottling equipment are some of the common machines utilizing TECAFORM®’s combination of properties. Typical applications are gears, wear strips, bushings, pump parts, fittings and rollers. No centerline porosity Low moisture absorption Excellent machinability Good combination of mechanical properties Resistance to food industry cleaning chemicals Good wear and abrasion properties Good dimensional stability Good property retention at elevated temperatures&& |
