Day 83:

What happens to plastic when it's warm?

Recycling of plastics can be done when the plastic (as long as it's a thermoplastic) is warmed above its glass transition temperature. Here is can be reshaped and then when it's allowed to cool it keeps that shape.

Today we warmed up a polymethylmethacrylate to see what temperature it started to get soft at.
