2 IntroductionFortron is a linear, partially crystalline polypheny-lene sulphide. A phenylene ring and sulphur atomform the backbone of the macromolecule and giveFortron a number of unusual properties [1], [2]: continuous service temperatures up to 240 C, short-term exposure up to 270 C, inherently flame-retardant (UL 94: V-0, somegrades 5 VA), very good chemical and oxidation resistance, high hardness and rigidity, very low water absorption, low creep, even at elevated combination of properties places Fortron in thecategory of a high-performance is suitable for the manufacture of mouldingswith good mechanical properties and most important applications for Fortron are inthe electrical and electronics industries (e. g. plugs andmultipoint connectors, bobbins, relays, switches,encapsulation of electronic components). Fortron isbeing employed increasingly in the automotive indus-try (air intake systems, pumps, valves, gaskets, com-ponents for exhaust gas recirculation systems).

3 Fortron is also used to produce components formechanical and precision many components exposed to high service stres-ses, Fortron is the preferred alternative to light-metalalloys, thermosets and many other thermoplastics. = registered trademark2. Grades, supply forms,colour range,quality managementFortron is supplied in powder and pellet form. Thecurrent range of grades is described in section compounding Fortron with glass fibres and glassfibre/mineral filler blends, its rigidity, strength andheat resistance can be considerably Fortron range includes extrusion and injectionmoulding grades with different types and levels ofadditive and different melt viscosities. Speciallyeasyflowing grades 1140L6, 4184L6, 6850L6 and6165A6 are available for thinwalled mouldings withunfavourable flow length/wall thickness ratios. Theirproperties are comparable with those of the corre-sponding grades with medium powder grades offer a variety of possibilities foruse in powder technology, e.

The recom-mended concentrations are 40 : 1 for black andbrown, 20 : 1 for the other processors wish to use their own colorants, onlypigments which can resist the processing temperaturesof Fortron (up to 350 C) without decomposition orcolour change may be employed.

Higher pigmentcontents may cause a reduction in mechanical pro-perties and following colour masterbatches are currentlyavailable:SD3002 K40blackSJ3013 K20greenSY3004 K40brownSN3012 K20orangeSC3010 K20dark greySL3017 K20yellowSC3011 K20pale greySS3006 K20redSG3005 K20blueAll colour masterbatches are properties such as tensile strength andelongation at break may be slightly altered by theaddition of should be noted that formulations cannot be ex-pected to give a permanently true colour match. Thisis because photooxidative reactions taking place underlight and heat lead to colour changes in very thin edgelayers of components.

The useof SPC methods to monitor Product quality is part ofthis quality system (see also the brochures QualityAssurance Polymer Material and Statistical ProcessControl ).By regular self-assessment in accordance with theautomotive requirements of QS-9000 we are con-stantly developing our quality system to meet theneeds of our foster effective partnerships with our customerswe offer to conclude quality agreements and also toissue test certificates. These agreements document thespecifications for our products. In addition, we canagree to issue an inspection certificate in accordancewith EN 10 This contains measured valuesrelating to the batch of which the delivery is sulphide (PPS) Fortron 52 Polyphenylene sulphide (PPS) Fortron 3.

The strength of a component dependsto a great extent on its design and hence designstrength is the criterion used to assess Mechanical propertiesTo characterize the dependence of the mechanicalproperties of a plastic on temperature, the shearmodulus G and the mechanical loss factor d are used,fig.
