Polymorph has which key property?

• A. Thermoplastic material that can be shaped and reshaped many times, supplied as granules; when heated to 62°C forms a clear mass.
• B. It is a metal alloy.
• C. It can only be used once.
• D. It is a ceramic.

Answer: (A)

Polymorph is a thermoplastic that can be shaped and reshaped many times. It starts as granules, which melt when heated to about 60–62°C and turn into a clear, moldable mass. Once it cools, it solidifies again and can be reheated to reshape. This repeatable melting and reshaping is what makes it useful for quick modeling and prototyping. It’s not a metal alloy, not a ceramic, and not limited to one use, which is why the described property is the best match.
