Question

Differentiate between thermoplastics and thermosetting plastics.​

Answer 1

Answer:

Difference Between Thermoplastic and Thermosetting PlasticThermoplasticThermosetting PlasticThermoplastic can be synthesized by the process called addition polymerization.Thermosetting plastics are synthesized by condensation polymerization.Thermoplastic is processed by injection moulding, extrusion process, blow moulding, thermoforming process, and rotational moulding.Thermosetting Plastic is processed by compression moulding, reaction injection moulding.Thermoplastics have secondary bonds between molecular chains.Thermosetting plastics have primary bonds between molecular chains and held together by strong cross-links.Thermoplastics have low melting points and low tensile strength.Thermosetting plastics have high melting points and tensile strength.Thermoplastic is lower in molecular weight, compared to thermosetting plastic.Thermosetting Plastic is high in molecular weight.

Answer 2

♦ Thermoplastics

1. It is synthesized by the process called addition polymerization.
2. It has have secondary bonds between molecular chains.
3. It posses low melting points and low tensile strength.
4. It is not fireproof.
5. Its Example :- Polystyrene, Teflon, Acrylic, Nylon etc.

♦ Thermosetting Plastics

1. These are synthesized by condensation polymerization.
2. It has a primary bonds between molecular chains and held together by strong cross-links.
3. It posses high melting points and tensile strength.
4. Its Molecular Weight is more than that of Thermoplastics & It is fireproof.
5. It Examples :- Bakelite, Melamine,
