Could 15mm plastic water pipe be affected by the solvent in expanding
foam?

Thanks

Does the solvent react with the plastic? Getting worried myself now as I
filled a hole in the bathroom where the plumber routed the bath waste
through the wall. I filled the whole with expanding foam.

I've used expanding foam on a few jobs in my old house and in this one.
I've never had a problem with the two reacting .... but there is always
a first time for everything :-) If you have a small piece of scrap pipe
spray a bit of foam on it first to check.

I know it probably isn't the answer your looking for but hope it helps.

Take care,
Ryan

I don't think it even bonds that well with plastic, let alone attack it.
Certainly the bits I managed to get on a pvc window came off easily enough

Chemicals in polystyrene, and some polyurethane foams, can leach out
the plasticiser from some plastics, making them brittle, is all I
know. Whether my foam (Polyfilla expanding foam) will damage the pipe
I linked to in my previous posting, I don't know.

The potential risk as I understand it is with plastic coated cables,
and possibly plastic water supply pipes - Sppedfit and so on. You
won't have an issue with waste pipes, or uPVC windows and doors,
because they are unplasticised.

I don't know to be honest, but if there was a problem, the packaging on the
foam would be knee deep in disclaimers. Never seen a warning about it.

Good point. Especially as the packaging even tells you what kind of
gloves to wear.

Yes. I didn't bother during my first experience with said foam, and
ended up with Vulcan ears[1] and plague-victim plastic skin. The second
time, I invested in one of those disposable forensic suits and some PVC
gloves. Some warnings are serious.

[1] I was filling gaps in the insulation in my shed roof, meaning that I
was basically in a box with foam dripping from the ceiling. I didn't
notice until it hardened that two big drips had landed on my ears.

Generally I have not had any problem with plastic pipe. The one area I
did have a problem was with a flexible plastic overseal that made a
joint on a (concealed) WC connector watertight. Turns out when filling a
gap in a bathroom some foam expanded onto this and eat through it. Lead
to a nice party trick where each time you flushed the loo water ran down
the kitchen wall below! Nice.

Phone JG and speak to a technical advisor. If they are as good as other
firms they will know.#
