I’ve made a silicone mould of a thin part (roughly 1mm thickness 100mm long)
Mixed the px90 at 1:1 ratio, and poured it into the mould.
3hours later I went to demould it and it’s super flexible (I can scrunch it up like paper) and I can rip it !
Isn’t the px90 supposed to be hard ? Is my part too thin to use px90?
Thanks

Being a toughened PU resin, it is likely to be ok depending on severity of impact, thickness cast etc. It is certainly a lot tougher than your typical PU casting resins.
