Is thermoplastic is a good insulator of heat?

Answer 1

yes thermoplastics are good insulators of heat

Answer 2

Thermoplastics can have varying levels of thermal conductivity, but they are generally considered to be poor insulators of heat compared to materials like wood or fiberglass. They can conduct heat easily, which means they are not the best for insulating applications where heat retention is critical. However, some thermoplastics can be modified with additives to improve their thermal insulation properties.
