Polyphenylene sulfide (PPS) is an organic polymer consisting of aromatic rings linked with sulfides. Synthetic fiber and textiles derived from this polymer are known to resist chemical and thermal attack. PPS is used to make filter fabric for coal boilers, papermaking felts, electrical insulation, specialty membranes, gaskets, and packings. PPS is the precursor to a conducting polymer of the semi-flexible rod polymer family. The PPS, which is otherwise insulating, can be converted to the semiconducting form by oxidation or use of dopants.〔David Parker, Jan Bussink, Hendrik T. van de Grampel, Gary W. Wheatley, Ernst-Ulrich Dorf, Edgar Ostlinning, Klaus Reinking, "Polymers, High-Temperature" in Ullmann's Encyclopedia of Industrial Chemistry 2002, Wiley-VCH: Weinheim. 〕 Polyphenylene sulfide is an engineering plastic, commonly used today as a high-performance thermoplastic. PPS can be molded, extruded, or machined to high tolerances. In its pure solid form, it may be opaque white to light tan in color. Maximum service temperature is . PPS has not been found to dissolve in any solvent at temperatures below approximately . An easy way to identify the compound is by the metallic sound it makes when struck. ==Manufacturers and trade names== PPS is marketed by different brand names and the manufacturers are China Lumena New Materials, Solvay (formerly Chevron Philips), Chengdu Letian, DIC Corporation, Kureha, Fortron (a joint venture between Kureha and Ticona, Toray Industries, and Tosoh. The following are examples of brand names by manufacturer and PPS type: * Tedur®, Albis Plastic, linear type * DIC.PPS, DIC Corporation linear/cross-linked * ECOTRAN®, INITZ, distributed and compounded via A.
