Acrylic Mountain…! Offers….?
I have been invited to make an offer on a huge job lot of Perspex in various thicknesses, colours (mainly clear) and sizes. It has been ‘stored’ outside in rough piles for a couple of years and needs sorting. Average sheet size 8’x4′ but plenty a lot bigger and if stacked on top of each other would make a pile over 10′ high!
I can see that some will go straight in the skip but wondered if anyone has a use for some speculative stock and an idea as to what ‘bid’ I should offer to make a bit of a killing!
Also, does it go ‘off’ over time and are any bent bits likely to stay bent once laid flat again?

The bid I would make is to clear it for free.
Perspex does not “go off” , the pigents can sort of discolour and depending on the type of acrylic ( Extruded is not great) it can craze or become brittle.
Th biggest problem will be scratches and the fact that protective coverings can become almost impossible to remove.
You can anneal bent Acrylic – IE heat it and let it air cool , cos acrylic has a “flat” memory – but this is very difficult and you really need a large convection oven or a huge oil bath for this – it wont go flat with weight or anything like that.
If we press form acrylic , we can take the formed sheet and reheat it to flat if there has been a bugger up.
Test the peices – the easiest way to test is to burn a small piece – Cast burns with a smoky crackly flame , extruded burns with a silent flame and drips molten flaming balls – if the majority is extruded , I would leave it.
another thing to look out for is tolerance on the sheet – Cast acrylic can be up to + and – 20% of thickness over a sheet – could be a problem.
I would want to know WHY the acrylic wasnt used and was left to “rot” over such a long time. -
I have a stack load of perspex…manly off cut, which i have had years
I must admit i haven’t used hardly any of it, as its never the right size..
But if they were 8×4 sheets they woiuld get used.
its ture what rodney says about scratches and the covering.
If you get it cheap.. and can store it, it may be worth the investmentSimon

Yep they have on some pieces
The guy renting the unit in which it was stored done a bunk leaving rental arrears and subsequently became impossible to contact. It was moved outside and lay there untouched until the first big winds came and it was left to do it’s own thing around the fields!!
I’ll try and pick the best bits and contribute to a skip for the rest!
Thanks

Dave does this guy sell offcuts im always looking for them as often to buy a 2050 x 1500mm half sheet makes me non competitive on flat cut routed letter jobs?

Hi Martin
Yes – He buys and sells. His range depends on what he buys. He’s mainly interested in off loading once he’s bought of course. Give him a ring and ask what he’s got available – his stock will change week to weekI’m sure you know that shelf life is not an issue.
Regards Dave Standen
