Does anybody have any experiences of glass filled nylon turning to dust. The application is a compressed air filter. The housing is aluminium, and the GFN component is fitted within the housing. It see's compressed air condensate, probably in the 7-16 barg pressure range, at anything upto 80 Degrees C. The condensate enters the filter as a vapour, and the GFN internals separate the water vapour from the compressed air. The GFN components have been decomposing so much that they can be crumbled between your fingers. I have had the condensate analysed for chlorides, sulphates, nitrates and any other cations and anions but the results were that there was nothing above 1ppm. The pH was 5.8. Am i missing something? What could be causing this damage.
