Material Compatability?

Seems like this should be in all the tubing catalogs, but I can't find it. I am looking for a material compatability table for Polyurethane and Polyethylene tubing vs Ozone and/or Propylene Glycol. Does anyone have a good source or web link?



Thanks

This table has chemical resistance for many polymers. As Pat said, when you need detailed information for a certain polymer, you'll need to contact the manufacturer or check their website.

The MAT WEB site was of no help. I don't know the exact compounds that are being used to make the tubing. It lists typical properties but not compatabilites? Unless I missed it.
I could call the manufacturer ( Parker), I tried their website, but didn't find anything on compatability.

Thanks

I still don't have a direction. Polyethylene and Polyurethane tubing both have similar compatibilites to Propolene Glycol, depending on which website you go to. Some sites rate them equal, others rate PE better than PU. I believe Polyethylene to be the more compatable choice?


Thanks

There are several types of PU which have quite different chemical resistance properties. Polyester and polyether types spring to mind, but there are significant variations within each type and I think also some other types.


Bayer, BASF, Merquinsa, Dow and Noveon are major suppliers and should cover most types between them

Laboratory equipment suppliers (like Nalgene or Plamer Labs.) sometimes have compatibility charts in their technical literature.
