PP (Polypropylene)
|
Features
- Most versatile chemical resistance of the thermoplastic materials identified as the sentinels of industrial piping.
- Suitable for mild solutions of acid, alkalis, hydroxides, salts and organic chemicals.
- Material of choice for drainage of mixed industrial chemicals.
- Half the strength of PVC or CPVC.
- Nemesis for PP are strong oxidizers such as hydrochlorites and higher concentrations of sulfuric, nitric and hydrofluoric acids.
- Performs up to the design stress of 1000 psi at 73°F.
- Joined by Heat fusion, Electrofusion and threaded.
