Impression Compound is a thermoplastic material which softens when heated and hardens when cooled,
A major advantage of impression compound materials is that they are very easy to adjust. Alterations to the impression can be made by removing replacing or adding material until a satisfactory result is obtained. Impression compound is more rigid when set and can be softened again if you need to make more adjustments. This helps achieve an accurate impression.
