Answer 2

Explanation:

Plastic Definition and Composition

Plastic is any synthetic or semisynthetic organic polymer. ... Thermoplastics and thermosetting polymers are the two types of plastic. The name "plastic" refers to the property of plasticity, the ability to deform without breaking.The polymer used to make plastic is almost always mixed with additives, including colorants, plasticizers, stabilizers, fillers, and reinforcements. These additives affect the chemical composition, chemical properties, and mechanical properties of plastic, as well as its cost.

Thermosets and Thermoplastics

Thermosetting polymers, also known as thermosets, solidify into a permanent shape. They are amorphous and considered to have infinite molecular weight. Thermoplastics, on the other hand, can be heated and remolded over and over again. Some thermoplastics are amorphous, while some have a partially crystalline structure. Thermoplastics typically have a molecular weight between 20,000 to 500,000 amu (atomic mass unit).
