	please try to google for TDS and MSDS before shooting up a question. http://www.google.co.in/search?hl=en&q=EPDM+chemical+resistance&meta=&aq=f&oq= Results 1 - 10 of about 68,800 for EPDM chemical resistance. (0.27 seconds) first entry http://www.standard-gasket.com/tech_specs/chem_res/chemical_resistance.htm Check the table and see for acetone EPDM = "E" or http://www.nero.co.uk/pdf/resistance.pdf The best one is from http://www.dupontelastomers.com/tech_info/chemical.asp but for that you have to register for access. __________________ Fantastic ideas for a Fantastic World, I make the illogical logical.They put me in cars,they put me in yer tv.They put me in stereos and those little radios you stick in your ears.They even put me in watches, they have teeny gremlins for your watches
