Material Compatability?

Material Compatability?

Material Compatability?

(OP)
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
Bill

RE: Material Compatability?

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
Bill

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

You mentioned ozone in your original post - is this still a requirement?

Ozone (in high concentrations) zaps all plastics (being hydrocarbons) PDQ.

RE: Material Compatability?

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

RE: Material Compatability?

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