Is PET a thermosetting or a thermoplastic polymer?
Pet( polyethylene terephthalate) is a thermosetting polymer.
Is polythene a thermosetting or a thermoforming plastic?
It is a thermosetting polymer
What is a thermosetting polymer?
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.
Is Bakelite a thermosetting polymer?
YES
Is nylon 66 a thermosetting polymer?
yes
What happens when a thermosetting polymer is heated for the first time?
When thermosetting polymers are heated for the first time, chemical bonds form between the polymer molecules. They link together in a giant network. These strong bonds make the plastic set hard and it cannot be softened again by heating.
Is bakelite a condensation polymer?
yes bakelite is a thermosetting plastic
Do thermosets melt reversibly?

What is the difference between simple and long chain polymer?
simple polymer are define as themosofning plastic where as long chain polymer define as thermosetting plastic
Why thermosetting plastics can not be remoulded?
Thermosetting plastics are condensation polymers of two different types of monomers as Bakelite plastic is the polymer of Phenol and formaldehyde, on melting such polymer become decomposed into smaller molecules and are unable for remoulding.
How is the polymer classified?
For example thermoplastic and thermosetting polymers, natural and synthetic polymers.
Is Teflon a thermosetting polymer?
teflon is thermoplastic as it contains a linear chain and is not crosslinked..
Do polymers conduct heat?
Yes, polymers do conduct heat. How well this happens depends on the polymer concerned.
What is thermosetting materials?
Thermosetting materials fuse under heat. The change is usually permanent.
Is copper a thermosetting plastic?
Copper is not thermosetting - if you heat it up enough it will melt - nor is it plastic.
Write the propertise of thermosetting plastic?
A thermosetting plastic, also known as a thermoset, is polymer material that irreversibly cures. The cure may be done through heat (generally above 200 °C (392 °F)), through a chemical reaction (two-part epoxy, for example), or irradiation such as electron beam processing.Thermoset materials are usually liquid or malleable prior to curing and designed to be molded into their final form, or used as adhesives. Others are solids like that of the molding compound used in semiconductors and integrated circuits (IC). Once hardened a thermoset resin cannot be reheated and melted back to a liquid form.According to IUPAC recommendation: A thermosetting polymer is a prepolymer in a soft solid or viscous state that changes irreversibly into an infusible, insoluble polymer network by curing. Curing can be induced by the action of heat or suitable radiation, or both. A cured thermosetting polymer is called a thermoset.[1]
Why is thermoplastic heat resisting?
ThermoSETTING polymers are heat resisting. Thermoplastic melts.
Two types of thermoplastic?
thermoplastics and thermosetting plastics thermoplastics go soft when exposed to heat thermosetting plastics set (harden) when exposed to heat only thermoplastics are recyclable
Is polyethylene thermoplastic or thermosetting?
Polyethylene is a thermoplastic polymer consisting of long chains produced by combing the ingredient monomer ethylene.
What is the definition of thermosetting?
Some kinds of materials that set with heat.
What are thermosetting and thermoplastics?
Thermoplastic can be reshaped a many times under HOT heat. Thermosetting plastic can be only shaped once and is more durable.
How does a polymer breakdown?
