PEX and Chemicals

I have read that PEX can be affected by petroleum based products. When sealing around PEX pipes where they pass through a wall can spray foam be used to seal the hole? Along the same line can spray foam be used around electrical wire in the same situation?

Look up the product name of spray foam and check out the MSDS specs.

It will give all statistics on what flammability levels are and other points to consider.

I would say yes without a doubt that it can affect PEX.
