Fortron 4665B6 Polyphenylene sulphide Celanese-Ticona Polysulfides SEALANT Fortron is a linear, semi-crystalline polyphenylene sulphide. A phenylene ring and a sulphur atom form the backbone of this macro molecule, lending Fortron a series of outstanding characteristics. Fortron is a well-qualified material for the manufacture of mechanically and thermally highly stressed moulded parts. Main areas of application are the automotive industry (eg. air suction systems, water and fuel pumps, valves, seals, components for exhaust feedback systems) as well as the electric/electronic engineering sector (eg. plugs and connector straps, coil bobbins, relays parts, switches, encapsulation of condensators, transistors and lamp sockets). In machine construction and precision engineering Fortron is also deployed for various components. Unreinforced PPS possesses a comparably medium heat resistance. Adding glass fibres and glass fibre/mineral mixtures allow the heat distortion temperature and the strength of Fortron to be attained. The following properties give Fortron its high performance polymer characteristics: operating temperatures up to 240°C, temporarily up to 270°C inherently flame retardant (UL 94:V-0, partly 5 VA) very good chemical and oxidation resistance high hardness and rigidity very low water absorption good creep resistance even at high temperatures Fortron is offered as powder or pellets. By the addition of glass fibres and glass fibre/mineral mixtures the unreinforced Fortron's rigidity and solidity as well as its heat resistance are substantially increased. The product range encompasses grades for extrusion and injection moulding that differ in regard to melt viscosity. Very easy flowing grades are available for thin-walled moulded parts with unfavourable flow path/wall-thickness ratios. The powder types allow for a wide variety of applications in powder engineering methods, for example as heat resistant binding agent or as an additive in PTFE compounds. The unreinforced pellet grades are mainly used in fibre production and for special applications in extrusion processing. Fortron contains a very low proportion of ion contamination giving it an advantage over other materials for electronic applications. For many kinds of moulded parts subject to a high degree of stress Fortron will be the better alternative compared to lightmetal alloys, thermosets, and many other thermoplastics. Unfilled Fortron is developed for high tenacity filaments, fibers and non-wovens in genreal industry and als the automotive industry. Special Fortron powders are available for coating applications.
