www.nylacast.com Page 1 of 14 CHEMICAL RESISTANCE TABLE The data given in the extensive Table below is the current ‘best state of information’ as known to Nylacast. Polymer compatibility with solvents other than those in this chart may arise: the General Principles to approach this issue are: -if a ‘new solvent’ is, say, a ketone then look for a similar solvent, e.g, look at the polymer compatibility of other ketones of higher or lower molecular weight. -the data given is for ‘room’, ~23oC, and 50oC temperatures. Solvents at higher temperatures, say >100oC, are usually more aggressive towards polymers and cause premature failure when compared to the lower temperatures for which data is given. Always test for higher temperature exposure. -Prolonged exposure, i.e., months or years, to solvents at room temperatures can denature polymer surfaces, causing surface stress cracking leading to physical failure. -do not expose ‘condensation polymers’ such as the nylons, PET/PBT and POM’s, to solutions with a pH of <2 or >12. Exposure of these polymers outside of these defined limits, such as to strong acids or alkalis, will begin to depolymerise and degrade the polymers which will lose strength and integrity. -some organic solvents will attack and ultimately dissolve polymers. Hot m-cresol, an unpleasant solvent, will dissolve nylons after prolonged exposure by refluxing. Some binary combinations of ionic liquids are good solvents of PVC or nylon polymers at room temperature or slightly above. Always test polymers for compatibility with ‘unusual’ solvents. -for a ‘new solvent’ not listed below, an unusual solvent or for listed solvents used at higher temperatures, always test the polymer under consideration for compatibility. -a blank box in the chemical/resistance table means that no information is available for that combination.
