Thermoplastic polymers can be reshaped by heating. So it is not deformed permanently. On the other hand thermosetting plastic has a cross linkage structure, so they cannot be reshaped once moulded.

So correct answer is themosetting plastic.

Yeah (B) thermoset.

Gautam10 said:   1 decade ago
Yes, correct answer is B.

Tsa said:   1 decade ago
But deform means changing of usual shape right?

Ponnusamy Thangarasu said:   1 decade ago
Yes, correct answer is thermosetting plastic (B)

Thermosetting plastic because the do not regain shape.

Subhash jha said:   1 decade ago
The thermoset polymers are highly cross linked polymer. So when it heated it cross link become damage or destroyed permanently so it cannot reform again.

Thermosetting polymers are permanently deformed when is the heating and cooling.

Thermosetting plastic because they do not regain shape.

Can some one explain beta cos? I think that thermoset cannot be reshaped or remolded so why thermoset?
