Why thermosetting plastics can not be remoulded?
There are two types of plastic: thermosetting and thermoplastic.Thermosetting plastics, such as Bakelite, use resins that are baked into their final form, usually in a mould. The chemical reaction of baking changes the resin so that it can no longer become fluid if reheated. These plastics cannot be "remolded", only powdered and put to other uses.Thermoplatics (the bulk of plastic materials) use resins that are not baked in their moulds. Thermoplastics are heated until they flow, then cast into shape. Because they are only heated to flow temperature, no chemical reaction of heating occurs, and they can be re-moulded in a recycling process.p.s. Bakelite is named for its inventor, Baekland, not because of its processing. True Bakelite is dark brown to black, so light-coloured "hard plastic" radio cabinets are *not* Bakelite - they are commonly Catalin, urea formaldehyde, or some other resin.
Is a wire thermoplastic or thermosetting plastic?
thermosetting plastic
What is thermoset used for?
Thermosetting plastics are used for resin and Bakelite, among other things. See http://en.wikipedia.org/wiki/Thermosetting_plastic#Examples
Do thermo plastics of cross links between chains?
Thermosetting plastics
What are some examples for thermosetting plastics which are used in electric sockets?
A wellknown example is bakelite.
What is thermal conductivity of Bakelite?
YES , Bakelite is a thermosetting plastic .
What plastic is used for saucepan handles?
Thermosetting plastics such as polyoxybenzylmethylenglycolanhydride better know as 'Bakelite' and some others.
Is polyester resin a thermo plastic or thermosetting?
Polyester resin is a thermosetting resin, generally a copolymer
What is thermo setting?
thermosetting is atype of plastic which can't be recycled
Is Bakelite thermosetting or thermoplastic?
thermosetting material
What was the first thermosetting plastic used to make?
Dr. Leo Baekeland made the first thermosetting plastic. He made this in the year of 1909 and it was originally called Bakelite.
What plastic is used for saucepans?
Thermosetting plastics such as polyoxybenzylmethylenglycolanhydride better know as 'Bakelite' and some others.
Can we substitute thermosetting plastics with thermo plastics?
Thermoplastics are the only ones that can be recycled. Thermosets cannot be recycled.
What is melting point of bakelite?
It doesn't have a melting point as it is a thermosetting plastic, meaning it can be heated but it will not melt, instead the temperature will be raised until it burns. Hope this help :D
Is Bakelite a thermoplastic?
thermosetting material
Why is the handle on a metal saucepan made out of plastic?
The black plastic used in plastic handles are a thermosetting plastic, typically Bakelite. Many other types of plastic, called thermoplastics will wilt and deform on heating.
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.
