Discuss the striking differences between thermoplastics and thermosetting plastics.

Explanation

### Step-by-Step Text Solution:

1. **Definition of Thermoplastics**:
- Thermoplastics are a type of plastic that can be easily deformed when heated. They can be melted and reshaped multiple times without undergoing any significant chemical change.

2. **Definition of Thermosetting Plastics**:
- Thermosetting plastics, on the other hand, are plastics that, once molded and set, cannot be remolded or softened by heating. They undergo a chemical change during the curing process, which makes them rigid and heat-resistant.
