Question

Quizplus · Accepted Answer

Melmac^® is classified as a thermosetting polymer because it cannot be melted and molded into new shapes once it has solidified. It is also rigid, which is consistent with the cross-linked structure of a thermosetting polymer. Melmac^® is not transparent like polycarbonate, nor is it elastic like polyurethane, making choices A and B incorrect.
