[2025-10-02T07:24:29.080982] [PI reasoning] **Analyzing impression compound properties**

I'm thinking about impression compound, which is a thermoplastic material used in dentistry. It softens when heated and hardens when cooled, so I know it's not thermoset. That means any statement calling it a thermoset is false. However, there are nuances about warping. It has a high thermal expansion coefficient, which can cause distortion when cooling. So, if it warps at room temperature, that's correct, especially if improperly managed or removed from the mouth.
