Aetna - Model PP - Thermoplastic Piping Systems- Brochure

Polypropylene (PP) is a member of the polyolefin family and is one of the lightest plastics known. It possesses excellent chemical resistance to many acids, alkalis 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. Typical applications include water treatment, clean chemical processes, pharmaceutical operations, industrial plating, waste treatment systems and food processing applications.
