What Are Thermoplastics?
Thermoplastics are a class of polymers that become pliable or moldable above a specific temperature and solidify upon cooling. Unlike thermosetting plastics, which undergo an irreversible chemical change, thermoplastics can be melted and reshaped multiple times. This unique property makes them highly versatile in manufacturing and material science.
