Hello all,

I was wondering if anyone has ever done a test by injecting heated liquid
polymer (for instance PE or ABS) into a well and tightly
surrounded/supported (vacuumcasting-type) of silicone mould.
Anyone have a clue what would happen?
Anyone know the Tg of the typical silicone material?
Are there flexibele (40-50 shore A) Urethanes or other pourable materials
with a higher Tg as silicone wich would suit to get better (heat)resistance?
Anyone have suggestions, theories or input if we do a test with it?
Waiting for your reply on our foreseen experiment, kind regards,

Jorn Berends
