Engineering guides for comparing polymers and selecting materials by performance, process, compliance, and cost.
PP is not one single material. PP-H, PP-R, and PP-B have different molecular structures, so their heat resistance, toughness, stiffness, and applications differ.
PA6 or PA66 grades cannot be selected by polymer name alone. Injection molding needs fast cavity filling, while extrusion needs melt strength and shape retention.
A practical framework for selecting PC/ABS compounds for automotive, appliance, electronics, and industrial molded parts.
