This question was posed to me in an online quiz.

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

Answer 1

Correct choice is (b) 95^oC

To explain: Melamine formaldehyde is an amino-formaldehyde material composed of melamine and formaldehyde condensation. They have properties similar to phenolics and urea-formaldehyde. However, they are more resistant to heat and can be used at temperatures up to 95^oC.
