Fortron^®

Product Finder

Fortron^® polyphenylene sulphide (PPS) is a high-temperature thermoplastic material that offers an excellent combination of thermal, mechanical and chemical resistance properties.

What is Fortron® PPS?

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.

Why Fortron® PPS?

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.

Product Properties

By adding glass fibers and glass fiber/mineral mixtures to standard Fortron^® PPS, it allows:

Service temperatures up to 240°C
Very good resistance to chemicals and solvents
Inherent flame resistant (UL 94 V-0, some grades 5VA)
Very low moisture absorption
Suitable for lead-free soldering
Excellent creep resistance even at elevated temperatures
