Wired Faculty App

What is the difference thermo – plastic polymers and thermosetting polymers? 

Solution

Thermoplastic polymers

Thermosetting polymers

1. Soften and melt on heating.

2.    Can be remoulded, recast and reshaped ?

3.    Less brittle.

4.    Soluble in some organic solvents.

5.    Usually formed by addition polymerization.

6.    Usually have linear structures.

7.    Examples. Polythene, PVC, Nylon, teflon, etc.

1. Do not soften on heating but burn if heated for a longer time.

2. Cannot be remoulded or reshaped?

3. More brittle.

4. Insoluble in organic solvents because of three dimensional cross-linking.

5. Formed by condensation polymerization.

6. Have three dimensional cross-linked structures.

7. Bakellite, urea-formaldehyde resin, terylene.
