Which characteristic is true for the base of an impression compound?

Show Answers

Has low thermal conductivityPossesses a crystalline arrangementUndergoes cross-linking when heatedExhibits a high melting point

Explanation

The base of an impression compound is known for its low thermal conductivity, which helps in maintaining temperature stability. It does not have a crystalline structure, nor does it form cross-links upon heating, and it does not have a high fusion temperature.
