Question

2. What are the main differences between thermoplastics and thermosetting plastics? Give one
example of each.​

Answer 1

Thermoplastic

1. Thermoplastic can be synthesized by the process called addition polymerization.

2. Thermoplastic is processed by injection moulding, extrusion process, blow moulding, thermoforming process, and rotational moulding.

3. Thermoplastics have secondary bonds between molecular chains.

4. Thermoplastics have low melting points and low tensile strength.

5. Thermoplastic is lower in molecular weight, compared to thermosetting plastic.

Examples : Polystyrene, Teflon, Acrylic, Nylon etc.

Thermosetting

1. Thermosetting plastics are synthesized by condensation polymerization.

2. Thermosetting Plastic is processed by compression moulding, reaction injection moulding.

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

4. Thermosetting plastics have high melting points and tensile strength.

5. Thermosetting Plastic is high in molecular weight.

Examples : Vulcanized rubber, Bakelite, Polyurethane, Epoxy resin, Vinyl ester resin etc.

Hope it helps you!!

Answer 2

Answer:

Thermoplastic

Thermoplastic ( also called Thermosoftening ) are plastic which will soften when heated and can be reshaped

Example Acrylonitrile butadiene styrene ( ABS ) is a thermoplastic used manufacture..

Thermosetting Plastic

are plastic do not soften on heating. They are used when resistance to heat is important
