Question

Distinguish between thermoplastics and thermosetting plastics

​

Answer 1

Answer:

thermoplastic can be bent easily

and used to make chairs

it is used to make cooking pan

like teflon

$\huge\underline\bold\red{Answer : }$

$\huge\star\underline\mathtt\purple{Thermoplastic -}$

• Thermoplastic can be synthesized by the process called addition polymerization.

• Thermoplastic is processed by injection moulding, extrusion process, blow moulding, thermoforming process, and rotational moulding.

• Thermoplastics have secondary bonds between molecular chains.

• Thermoplastics have low melting points and low tensile strength.

• Thermoplastic is lower in molecular weight, compared to thermosetting plastic.

$\huge\star\underline\mathtt\purple{Thermosetting -}$

• Thermosetting plastics are synthesized by condensation polymerization.

• Thermosetting Plastic is processed by compression moulding, reaction injection moulding.

• Thermosetting plastics have primary bonds between molecular chains and held together by strong cross-links.
• Thermosetting plastics have high melting points and tensile strength.

• Thermosetting Plastic is high in molecular weight.
