PVC

Polyvinyl chloride (PVC) is a low-cost plastic, ideal for parts that require strength while remaining lightweight. It is highly machinable to close tolerances and has excellent corrosion, flame, and water resistance. PVC also has high strength, impact resistance, and toughness.

PVC has a machining cost factor of 1.1 when compared to steel 12L14.
