GPPS GON N1841/N1841H are Optical & injection molding grade GPPS, featuring easy flow and well-balanced comprehensive properties. Two variants available for selection as required: standard N1841 and N1841H with subtle blue tint.
Low melt viscosity brings smooth filling during injection molding, suitable for thin-wall and complex-shaped products, shortens molding cycle and improves production efficiency.
Stable mechanical rigidity, good transparency and uniform appearance, with balanced physical and optical performance for universal injection molding scenarios.
