PU Foam and T&E cable

[JohnW2]

Just been told of PVC cable that turned almost black where it was in contact with some sort of foam sealing the end of a underground duct.

Well, we all know what polystyre foam (or expanded polystyrene) can do to PVC cables - maybe that's what this foam was?

Kind Regards, John

Have you ever had to remove it to add in more cabling?

Not even sure in the damn stuff is fire rated.

I'm sure it has, but I can't think of a time.

Not much need for fire protection in a standalone cubicle.

You can buy fire rated expanding foam. I use it quite a lot these days. It's great stuff.
