Application

Poly(1,4-phenylene sulfide) serves a multifaceted purpose due to its exceptional properties. This polymer is notably strong and rigid, though it exhibits some brittleness, and is typically processed into a crystalline form using heated molds due to its high glass-transition temperature (90°C). Its key attribute is thermal stability, maintaining robust mechanical properties even at temperatures reaching 250°C. Furthermore, it boasts excellent electrical insulation and is highly resistant to a broad range of solvents, acids, and alkalis, with the exception of concentrated sulfuric acid. Poly(1,4-phenylene sulfide) is mainly employed in injection molding to manufacture electrical components, automotive parts, and equipment that must withstand corrosive environments. Beyond these uses, it can be sulfonated to create proton exchange membranes with enhanced thermal stability for solar cell production and to form organic-inorganic nanocomposite membranes for high-performance gas separation. Additionally, sulfonated and chloromethylated forms of this polymer can lead to novel fibers with improved dyeing capacity, expanding its applications in various industries.
