Thermosetting plastic materials___________________?
Correct answer: C. Cannot be melted after forming
- A. Can be repeatedly melted
- B. Is useful for melt casting
- C. Cannot be melted after forming
- D. Is useful for spinning
Explanation
Thermosetting plastics form permanent cross-linked networks during curing, so they cannot be melted and reshaped after forming. Repeated melting, casting, and spinning are characteristics of thermoplastics.
