Answer:

The two types of plastic are:

1. thermosets (cannot be melted)

2. thermoplastics (can be melted)

Thermoplastics

Thermoplastics such as polyethylene and polystyrene are capable of being molded and remolded repeatedly.

Thermoplastics can be recycled. They are further of two types:

1. Amorphous (polystyrene, polycarbonate etc.)

2. Semi-Crystalline (PET, nylon etc.)

Thermoset is a material that strengthens when heated, but cannot be remolded or heated after the initial forming.

Thermosets can't be recycled.
