Question

write any 3 differences between Thermoplastic and Thermo setting plastics​

Answer 1

Answer:

1.The primary physical difference is that thermoplastics can be remelted back into a liquid, whereas thermoset plastics always remain in a permanent solid state.

2.Thermoplastic can be synthesized by the process called addition polymerization. Thermosetting plastics are synthesized by condensation polymerization.

3.Thermoplastics have secondary bonds between molecular chains. Thermosetting plastics have primary bonds between molecular chains and held together by strong cross-links.

Answer 2

Answer:

Here is ur answer,

Explanation:

Thermoplstic:-

1. Thermoplastic substances can be melted and formed into shapes that become hard, and can then be melted again.
2. Thermoplastics are linear polymers.
3. They undergo no chemical change in the molding operation.
4. They can be softened again and again.
5. These plastics can be reused.

Thermosetting plastic:-

1. Thermosetting substances can be melted and formed into shapes that become hard and cannot be melted again.
2. Thermosetting Plastics are cross-linked polymers.
3. They undergo chemical change in the molding operation.
4. They cannot be re-softened once they hard.
5. These plastics cannot be reused.
