Product Description
Amodel A-4422 LS resin is a 22% reinforced, light-stabilized, high-reflectivity white grade of polyphthalamide (PPA). The material exhibits high heat resistance, high strength and stiffness over a broad temperature range, low moisture absorption, excellent chemical resistance, and excellent electrical properties.

Its rapid crystallization rate and high flow characteristics can result in shorter cycles, thereby enhancing molding productivity and lowering costs.
