Thermosetting plastic materials___________________?
Correct answer: A. Cannot be melted after forming
- A. Cannot be melted after forming
- B. Is useful for melt casting
- C. Can be repeatedly melted
- 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.
