Acrylic doesn't have as much impact resistance as polycarbonate; polycarbonate's tensile strength is greater than that of PVC; PVC's heat deflection abilities are lesser than Vivak's; and so on, and so on. Specific gravity and density are especially relevant because plastic is sold on a cost per pound basis and a lower density or specific gravity means more material per pound or varied part weight. There are two basic test procedures- Method A and Method B. The more common being Method A, can be used with sheet, rod, tube and molded articles. How about an incentive to share this post? Polyvinyl acetate 1.19 For example, some types of plastic are reusable and others arent because of the chemicals they contain; some can be recycled and others need to be disposed of in a different way.
