abs vs polycarbonate

Engineering plastic selection is a decision that is expensive to reverse: the polymer sets the service temperature, the impact behaviour, the chemical resistance and the wear life of a part long before the mold is cut, and changing material later usually means a new gate position, a new shrink allowance and a new tool. ABS, polycarbonate, polyamide and POM cover most of the parts buyers ask for, and each one wins on a different property. This guide compares the four families on heat, impact, chemical and wear performance, sets out a selection path you can work through with a drawing in hand, and shows what each choice does to molding conditions, cost and lead time.
