Polypropylene (PP) is a member of the polyolefin family; PP is one of the lightest plastics known. It possesses excellent chemical resistance to many acids, alkalies and organic solvents. PP is one of the best materials to use for systems exposed to varying PH levels, as many plastics do not handle both acids and bases well. It is not recommended for use with hydrocarbons and aromatics. Its upper temperature limit is 195° (90° C). Proline™ is available in 150 psi and 45 psi standard. Options in 90 psi are available. Proline® is available from 3/8" (16mm) to 54" (1400mm).
