"Remeltable PVC - any reviews" Topic

I see this in my local Hobbycraft
link
Has anyone used it? Does it have a use for mould making. I'm assuming the low-melting point would make it useless for resin casting but I'm intrigued as to whether anyone has found a use for it.

I had something similar a few years back and it was fine for casting resin. The melting point is pretty high being 130C. The main difficulty I had were the smell while it melted and worrying that I would burn it – not that I ever did.
The moulds were fairly rigid as long as the wall around the item were strong enough. The first thing I made was a tent from plasticene – which melted when I poured the PVC over (duh!).
The next master I made was also plasticene but I varnished it or something. Whatever it was, the master survived to create a usable mould.
As it happens there is an example online of what I made

Whatever the standard of the modelling it shows that the detail is quite sharp.

It's good stuff, particularly for plaster casting. You might be better buying it from here link or here link where it is half the price of Hobbycraft.

Thanks. Nice tent. Looks like it does hold detail better than I thought it may. I wasn't thinking as a replacement for RTV but sure I could use it somehow.
Also thanks for the tip on purchasing – I probably wouldn't have got it from Hobbycraft as I find their prices eye-watering usually.
An interesting comparison:
Hobbycraft Trylon Silicone Rubber 250 Gram £20.99 GBP
Tiranti T20 Silicone Rubber 1.05kg £22.06 GBP

I use Tiranti for my RTV so I can easy add this to an order.

Thanks again

This material sounds similar to Vinamold.
The MSDS is worth reading:
PDF link

It is called Vinamold in the alternative shopping links. Was there anything particular you were highlighting in the MSDS? Doesn't look any worse than the resin i already use in terms of hazard or environmental harm ? Except the 2nd degree burns but I'd expect that from plastic heated to 150 degrees. Also the link you put is from my resin supplier so another purchase avenue there.

ok trylon/vinamold melts 135-150 Celsius
question
using it as 2 part mould, lower half sets ,you pour top part of mould will top part transfer heat to bottom half thereby softening/ distorting bottom half
I use plastic card as part/all of my masters what temp does plastic card melt would it be affected by the sustained heat from the mould
