At lower temperatures, economical PVC offers a combination of excellent chemical resistance, high mechanical strength, and low moisture absorption. CPVC increases both weather and temperature resistance, expanding design versatility. Both materials are easily vacuum formed, thermoformed and fabricated, and can be glued, cemented, welded and varnished.
PVC is very dense compared to most plastics
PVC is readily available and cheap.
Rigid PVC is very hard.
Rigid PVC has extremely good tensile strength.
