Any plastic that if you put a flame to it , it will char/ burn/go black.
NB A thermosoftening plastic is one , if heted, will just change shape.
As a 'rule of thumb' opaque plastics are thermosetting; clear plastics are thermosoftening.
Thermosetting
Urea-formaldehyde is a thermoset plastic. Once it is cured, it undergoes a chemical reaction that permanently sets its shape, making it hard and durable. Thermoset plastics cannot be reshaped or melted once they are formed.
Thermoplastic operations involve blowing a heated plastic into a mold. The end product is hollow. Thermoset plastics are sheets of plastic heated and place over two parts of a mold that come together. The end result is not hollow.
A plastic spoon is a thermoplastic. If heated further, it becomes pliant and it can be melted or remolded.
Thermosetting resins are plastics that are usually heated and have plastic properties during the moulding process, but on cooling forms complex cross linking , and cannot be remelted or reshaped by re-heating.Examples are Bakelite(phenol-formaldehyde resins) and urea-formaldehyde resins used in electrical swithes, etc. Plastics which can be re-shaped with heat are called thermoplastics. Examples are polyethylene,polyvinyl chloride(PVC) ,polystyrene and nylon.They basically consist of long chain molecules coiled around each other, without cross-linking.
no
The answer is thermoset :)
Basically there are two types of thermoplastic, thermoset and thermoform. Thermoset becomes hard when heated an example would be Bakelite. A thermoform plastic gets soft when heated and can be reformed. An example would be abs such as used in plastic pipe. Gil
UHMW stands for Ultra High Molecular Weight. Now it depends what the monomer is. UHMWPE would be thermoplastic not thermoset. But other UHMW polymers can be thermoset. It depends.
i think its a thermoplastic I'm not too shore but when its heated it melts so yeah i guess so :)

Most plastic do not conduct heat very well, This makes it ideal for handles on pans which makes it Thermoset.
The two types of plastics that start with thermo are thermoset plastic and thermoplastics plastic.hope that helps you! x
It is a thermoplastic! :)
thermoplastic
Thermoset plastics cannot change shape because they undergo a irreversible chemical reaction during the curing process. This reaction, known as crosslinking, creates strong bonds between the polymer chains, making the material rigid and inflexible. Once set, thermoset plastics cannot be melted or reshaped like thermoplastics.
