These Charts show the thermal deformation temperature and the softening temperature (called the âVicat softening temperatureâ) of major plastics. The heat distortion temperature is the temperature when the test piece placed in the heat medium with bending load applied reaches a specified deflection as temperature rises. The Vicat softening temperature is defined as the temperature where the needle shaped penetrator sinks into the test piece to a specified depth as temperature of the heating medium rises and specified vertical load is applied to the test piece.
So I wouldn't consider heating plastic. It will melt if the heat is to great. You will likely not heat your terrarium hot enough to melt most rigid plastics if you have plants inside. Whether it will melt depends upon which plastic your terrarium is made of and what temperature you are heating it to. A lamp heater posed some distance above the terrarium should not increase the temperature beyond what is comfortable to touch.
