Final answer:
Technician B is correct. Thermoset plastics cannot be heated and reshaped.
Step-by-step explanation:
Technician B is correct. Thermoset plastics cannot be heated and reshaped. Unlike thermoplastics, which can be melted and reformed multiple times, thermoset plastics undergo a chemical reaction during their formation, resulting in a permanently set and stable structure. This makes thermoset plastics more durable and resistant to heat, chemicals, and electricity, but it also means they cannot be reshaped or melted again without undergoing degradation or damage.
