The Fortron® PPS chemical structure provides excellent chemical and thermal resistance. Insoluble in all known solvents below 200°C (392°F), it has very good stability in both typical and alternative automotive fuels.
In addition, Fortron® PPS can be extruded with melt-blown and spunbonded technologies for melt-spun nonwovens. Unfilled, high viscosity Fortron® PPS is also suitable for extrusion and compression molding to produce sheets, rods and other stock shapes commonly used for prototyping.
PPS is inherently flame resistant and is virtually unaffected by a broad range of chemicals, even over prolonged periods and at elevated temperatures. It is commercially available in two varieties: branched (cross-linked and cured) and linear. Linear PPS is a second-generation product that offers easy processing, excellent lot-to-lot consistency and high strength and toughness. It is available in a range of molecular weights that allow it to be used in a variety of processes from thin section injection molding to blow molding. It also has low ionic impurities and is colorable.
