Polyphenylene Sulfide (PPS) is a thermoplastic polymer formed by the reaction of 1,4-dichlorobenzene and sodium sulfide, consisting of aromatic rings linked by sulfides.
PPS is thermally, chemically, and mechanically stable in a broad range of chemicals (acid and alkaline solutions) at prolonged periods and at elevated temperatures.
PPS finds its utilisation also in hydrogen piping filters for its high hydrolysis resistance and as corrosion protection of ferrous metals in the chemical and construction industries.

PPS yarns, due to their excellent alkali resistance are widely used in alkaline water electrolysis (AWE) for hydrogen production.
AWE is a process of using electricity (anode and cathode) to split water into hydrogen and oxygen and get pure hydrogen through filter and dealkalization. By using renewable electricity (wind turbines /solar panels) it is a modern, effective and environmentally friendly technology.
PPS woven membranes (diaphragm) prevent the mixing of hydrogen and oxygen molecules.
