One for the real techies here...
I'm considering a complete change in the way I produce my castings and going down the route of hot melt vinyl rubber in place of messy RTV silicone.
To cut a long story short, the hot melt stuff requires heating upto 150 C - 160 C and should be poured at 140 C - 150 C.
Therefore my question is; as most of my masters I'll be making casts of are mainly made of styrene plastic, I want to know if styrene will withstand having a liquid of that temperature poured onto it without it warping etc?
