TECAFORM® AH FG is an acetal copolymer (POM-C) pigmented a brilliant blue so that any fragment entering a product stream is visible to optical inspection equipment and so operators can verify that a part is clean. It carries the mechanical profile that makes acetal the default machining plastic: 8,800 psi tensile strength at yield, 250,000 psi tensile modulus, 25% elongation at break and Rockwell M86 hardness, with a heat deflection temperature of 316°F at 66 psi and 195°F continuous service. Moisture absorption is only 0.22% in 24 hours and 0.8% at saturation.
The grade is intended for food-contact service and is used in food processing, beverage filling, packaging and paper machinery, and pharmaceutical equipment: star wheels, guide rails, timing screws, scrapers, bushings, gears and valve components. Extruded stock is porosity-free, which matters for washdown parts and for holding tight tolerance on thin sections. Acetal machines faster and cleaner than almost any other engineering plastic and needs no special tooling. Limitations: it is attacked by strong acids and oxidizing agents, it is not UV stable without modification, and chemical resistance is narrower than polyethylene in aggressive cleaning regimes.
