Question

explain the difference between thermoplastics and thermosetting plastics
​

Answer 1

Answer:

The primary difference between the two is that Thermoset is a material that strengthens when heated, but cannot be remolded or heated after the initial forming, while thermoplastics can be reheated, remolded, and cooled as necessary without causing any chemical changes.

Answer 2

Answer:

THERMO PLASTIC

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.

THERMOSETTING PLASTICS

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.
