"it is a thermosetting plastic because its formation is by Step reaction Polymerization(Condensation) which is a thermoplastic."
that is a uniquely idiotic answer.
there are plenty of instances when a condensation reaction leads to a thermosetting polymer: phenol formaldehyde resins are just one instance.
the key is the effective functionality of what is condensing. in unsubstituted (on the ring) aniline, the effective functionality is 3: both ortho positions and the para positions are open to the formaldehyde reaction. and that, my friends, leads to a crosslinked or thermoset polymer.
if your aniline is blocked in one of those positions, say, as in p-anisidine, then, yes, you will largely get a thermoplastic (save for the defects, etc.)

What type of plastic is old TVs made from?
The plastic that is used for preparing a television cabinet is melamine resin. It is a thermoplastic material created through the polymerization of melamine and formaldehyde.
What is the color of phenol formaldehyde resin after it is prepared?
Phenol Formaldehyde Resin in liquid phase appear as rides brown.
What are the dangers of Urea-Formaldehyde resin?
It is poisonous
What does thermosetting plastic mean?
the structure of thermosetting plastics are Ø Thermoplastics have long chains which are tangled together in no formal pattern Ø They have very few cross links which means that when heated they become soft allowing them to bent, pressed and formed into different shapes. Ø They become stiff as they cool
How to manufacture urea formaldehyde resin?
The laboratory preparation of urea-formaldehyde with melamine formaldehyde resin added is meant to modify the urea-formaldehyde resins in order to get good performance with a low formaldehyde emission. The optimal percentage of the melamine resin is 20 percent of the entire solution.
Is polyester thermoplastic or thermosetting?
Polyester resin is a thermosetting resin, generally a copolymer

What is the difference between phenolic resin and urea formaldehyde resin?
Phenolic resins are made from chemicals of the phenol group while urea formaldehyde resin are made from urea and formaldehyde. These two resins have different properties.
Is formica a thermosetting plastic?
Formica is a composite material. Melamine, the resin used in it, is thermosetting.
What are 3 types of thermo plastics?
The three I can think of are polyester resin ,urea formaldehyde and polyurethane
What is rtr pipe?
Reinforced Thermosetting Resin Plastic (RTRP) Pipe.
What is chemical content of material for Backalite?
Bakelite is based on the thermosetting phenol formaldehyde resin polyoxybenzylmethylenglycolanhydride, developed in 1907–1909 by Belgian Dr. Leo Baekeland, formed by the reaction under heat and pressure of phenol (a toxic, colourless crystalline solid) and formaldehyde (a simple organic compound).
What is the structure of bakelite?
Bakelite is a thermosetting plastic. Its structure is made up of extensively cross-linked chains, which stop the chains from unfolding.
