What does thermoplastic mean?

thermoplastic, or Thermosoftening plastic, is a plastic polymer material that becomes flexible or moldable at a certain high temperature and solidifies when cooled. Most thermoplastics have high molecular weights.

Which thermoplastic is correct?

The correct statement about thermoplastic polymers is that thermoplastic polymers are Linear polymer (or) branched polymer. So, the correct answer is option C.

What does the term thermoset mean?

: Able to become permanently rigid when heated or cured thermoset resins — Compare thermoplastics.

What is thermoplastic very short answer?

Thermoplastic is a material that is usually plastic polymer, softens when heated and hardens when cooled. Thermoplastic materials can be cooled and heated multiple times without changing their chemical or mechanical properties. When thermoplastics are heated to their melting point, they melt into a liquid.
