Question

Which of the following is a property of thermosetting plastics?

(a) Can be molded

(b) Soft

(c) Recyclable

(d) Can be used at high temperatures

I had been asked this question in an interview for job.

I want to ask this question from Thermosetting Plastics, Particle Reinforced Composites in section Non Metallic Materials of Engineering Material & Metallurgy

Answer 1

Correct option is (d) Can be used at high temperatures

The best explanation: Thermosetting plastics become permanently hard when they are heated and do not soften on further change. This makes it impossible for them to be molded into different shapes, rendering them unrecyclable. However, they are good to use even at high temperatures.
