• Plasticised PVC?

    Posted by Martin C on January 23, 2004 at 2:03 pm

    I’ve just stuck two pieces of Foamex together using some spray adhesive I bought from the local hardware shop. I hastlily read the details and it said, suitable for wood, metal, plastic and foam to foam (it’s main use is for sticking carpets down).

    Now I see it says ‘not suitable for Plasticised PVC’. 😮

    Is Foamex plasticised PVC or Plastic………or something completely different? I wouldn’t have looked but wanted to clean off some overspray and it just rubbed off like rubber so am a little concerned that it will stay stuck! 😕

    Martin,

    I belive I’m correct in saying that unless it states its uPVC (unplasticisedPVC) it will contain plasticiser.
    We’d normally use double sided mount film for indoor use
    (if the need arose), so I can’t suggest a glue, sorry.

    Let’s hope someone else can help.

    Cheers Peter

    looks like this may do the trick – Fusion 500
    although I can’t recommend it.

    Superglue works a treat on foamex.

    I use pvc gutter (pipe) adhesive. Osma for example. Sticks like **** to an army blanket.

    as big g said – try the guttering upvc solvent glue. I’ve had stuff stuck up with this for years.
    Don’t bother looking for it on the shelves at B&Q – they keep it at the checkout – just ask.
    cheers

    Stelmax ! Available from any PVC Cladding & guttering suppliers.
    Drys almost as quick as superglue and stays stuck forever !

    Thanks all. I’ll try the plumbers glue next time which I’ve used before but it doesn’t really answr my question as to what Foamex actually is? i.e. is it Plastic or PVC? Sorry to be so dumb but I wasn’t great at Biology at school 😕

    Martin,

    Dont you mean Chemistry 😆 I got a “D” in A-level chemistry so I can’t really talk can I ?!!

    As far as I know though Foamex (or any other brand) is pretty much the same material as solid pvc but it has been “aerated” , that is it has lots of little air gaps put in it to make it lighter weight. You can see these gaps if you look close at the cut edge of a sheet. Its a bit like the difference between solid styrene plastic sheet and expanded polystyrene only with less air bubbles !

    So consequently I guess it is safe to say that it does have platisisers in it and that most pvc glues will work well on foamex too.

    Thats what I think anyway, but dont quote me !!

    I wouldn’t argue about it Nik, as I’m not confident enough on this one 😕

    I looked up this on Alcans site….

    “FOAM-X® is a featherlight, affordably priced light material sheet with very good flatness, especially designed for the display market. The sheet consists of an elastic, closed-cell structure core of expanded polystyrene and strong, white chromopaper liners. ”

    but subsequently John has pointed out that this is not the same stuff as Foamex and so the description is somewhat irrelevant 😳
    Still can’t find a definate answer to the original question !

    It also says that “…standard PVC adhesives which are designed for jobs in the building industry are neither transparent or uv stabilised.Joints would remain visible and may even discolour when exposed to outdoor conditions”
    “The recommended adhesive is UV-stabilised, transparent diffusion adhesive based on the solvent tetrahydrofurane (THF)”

    Nigel,

    “The sheet consists of an elastic, closed-cell structure core of expanded polystyrene and strong, white chromopaper liners.”

    Are you sure that you’re thinking of the right stuff? What you have described sounds more like that foam centred card used for mounting photos and the like.

    John,

    Yeh, it does doesn’t it – I just copied it from their web site, but I think I may have goten myself even more in a hole with the difference between “Foam-X” and “Foamex” ??

    The adhesive info is from a different source and I think stands correct, at least.
    Maybe I was right afterall in my first post – I think I’d better stop digging 😉
