Material Notes:
Amodel A-4122 NL resin is a 22% glass reinforced, high-reflectivity white grade of polyphthalamide (PPA), designed to provide high crystallinity when molded in water-cooled molds. This material exhibits high heat resistance, high strength and stiffness over a broad temperature range. It also offers low moisture absorption, excellent chemical resistance and excellent electrical properties. Its rapid crystallization rate and high flow can result in short cycles and therefore high molding productivity and lower part cost. - White: A-4122 NL WH 905Injection Notes: A general purpose screw is recommended, with minimum back pressure. Injection Pressure: 3 to 4 in/secInformation provided by Solvay Specialty Polymers.
