May 14, 2010 #2 patprimmer New member Nov 1, 2002 13,816 Have you by any chance considered asking various raw materials suppliers to quote on each. DuPont, BASF, DSM and Ticona spring to mind. I am sure there are many others in your region where ever that may be. Oh and you need to take SG into account. You probably should also consider cycle times and other processing costs if this is a real project and not just a purely academic question.

May 15, 2010 #3 Demon3 Materials Jun 6, 2005 1,850 Yes, as Pat says don't forget SG (specific gravity or density) as you need to consider price per liter, not price per unit weight. The density is extra important for automotive applications as it translates to gas mileage. To answer your question fully would require an analysis of historic pricing for both over a 5 year period or longer.

May 15, 2010 #4 Demon3 Materials Jun 6, 2005 1,850 The latest information I have is that on a weight basis, PA6 is cheaper than PBT which is cheaper than PA 6,6. I expect the glass filled materials follow the same trend. You can find resin pricing online to check the latest trends.
