Polystyrene foam in epoxy resin heat amp chemical reaction test

I'm planning to make a bench-top kind of thing very soon, and I'm testing suitable materials for it. So in this video, I throw a chunk of very dense polyurethane foam into a glass of epoxy resin to see the results. Not a great deal happens for a rather long time haha. • • Here are the temperatures of the resin in (roughly) 5 minute increments: • • • • • Time 0:00:00 • Degrees Celsius: 19.5 • • Time 0:03:30 • Degrees Celsius: 22 • • Time 0:05:00 • Degrees Celsius: 21 • • Time 0:10:00 • Degrees Celsius: 20.7 • • Time 0:15:00 • Degrees Celsius: 22.4 • • Time 0:20:00 • Degrees Celsius: 24.5 • • Time 0:25:00 • Degrees Celsius: 24.9 • • Time 0:30:00 • Degrees Celsius: 29.4 • • Time 0:35:30 • Degrees Celsius: 31.5 • • Time 0:40:40 • Degrees Celsius: 32.7 • • Time 0:45:00 • Degrees Celsius: 35.9 • • Time 0:50:00 • Degrees Celsius: 35.6 • • [Heatgun used] • Time 0:51:30 • Degrees Celsius: 42.7 • • Time 0:55:00 • Degrees Celsius: 45.8 • • Time 1:00:00 • Degrees Celsius: 65.7 • • Time 1:01:50 • Degrees Celsius: 75.2 • • Time 1:05:10 • Degrees Celsius: 93.5 • • Time 1:09:30 • Degrees Celsius: 99.3 • • Time 1:14:45 • Degrees Celsius: 59.6 • • • • • The foam didn't react the least bit to the epoxy resin itself, which is most marvellous, and it took some 90-100 degrees Celsius to melt it, so it should be quite adequate for the purpose I have in mind for it. • • As for that purpose - stay tuned! i have almost everything i need ready, so I'll be making it very very soon!
