Answer: hope it helps please mark as branliest

Explanation:

Thermosetting plastic. 1- In thermosetting plastic cannot be bent easily. It may break when forced to bend. 2- thermosetting plastic cannot be softened by heating. Does it cannot be reshaped once moulded.

3- example÷ bakelite melamine.

Thermoplastic. 1- thermoplastic can be banned easily. 2- thermoplastic can be soft and easily by heat thus it can be reshaped. 3- example ÷ pvc, polythene.

Biodegradable÷ Biodegradable means that it can be broken down by living things like bacteria and fungi (these are microorganisms). Degradable means they do not require living organisms to break down. Instead, chemical additives are used in the plastic to make it crumble more quickly than it would otherwise.

Answer 2

A thermoplastic polymer can be repeatedly softened on heating and hardened on cooling. Hence, it can be used again and again. The examples are polythene, polypropylene, etc. A thermosetting polymer is a permanent setting polymer as it gets hardened and sets during moulding process and cannot be softened again.

A Non-Biodegradable material can be defined as a kind of substance which cannot be broken down by natural organisms and acts as a source of pollution. ... Non-biodegradable wastes are those who cannot be decomposed or dissolved by natural agents. They remain on earth for thousands of years without any degradation.
