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
Thermosetting polymers are those that, once reacted and molded cannot be remolded. An example would be an epoxy resin reacted with a polyamine. Once it has cured if you try and heat the polymer, it will not melt but char and even burn.
They are the opposite to Thermo Plastics.
Essentially, when you heat a thermosetting plastic- it will stay in that shape for the rest of its lifetime. It cannot be reverted.
Thermoplastics... (the recycleable ones such a PET and PVC) will change shape over and over again when heated.
i.e. heat pvc, bend it to a rectangle, leave to cool
then reheat it and change its shape again.
You cannot do this with thermosets.
Epoxy resin, melamine formaldehyde, urea formaldehyde are 3 thermosets.
Thermosetting plastic is a hard plastic. Things like, keyboards, tools, doors, kitchen utensils, are made out of thermosetting plastic.
thermosetting plastic is where the thermosetting plastic thermominates the plastic
SIMPLES lol
They are used for many things such as kitchen utensils and also for things such as light fittings.
Thermosetting plastics are plastics when moulded into shape and allowed to cool will not change shape; when heated again they will char or burn.
Thermoplastic can be reshaped a many times under HOT heat.
Thermosetting plastic can be only shaped once and is more durable.
After taking the form of plastics they will prove to be thermosetting.
setting after melting and moulding with change of properties
thermosetting plastic
It is a thermosetting polymer
Copper is not thermosetting - if you heat it up enough it will melt - nor is it plastic.
No. It is a liquid metal.
Polyethylene is a thermoplastic polymer.

the opposite to thermosetting plastic is thermoplastic
They are thermosetting plastic and thermoplastic!
the opposite to thermosetting plastic is thermoplastic
yes
yes
thermoforming plastic is completley the oppisite of thermosetting!
Formica is a composite material. Melamine, the resin used in it, is thermosetting.
Polyester resin is a thermosetting resin, generally a copolymer
