Did you know all plastics fall into only 2 categories when it comes to their reaction to heating? These 2 categories are called Thermoplastic and Thermosetting.
Thermoplastic materials become soft when they are heated and solid when cooled to room temperature. This is similar to heating and cooling wax. Thermoplastics are materials such as acrylics, cellulosics, polyamide, polystyrene, polyethylene, fluoroplastics, polyvinyls, polycarbonate, and polysulfone.
Thermosetting materials cannot be reheated and softened again. Once these are formed they cannot be reformed. This is simliar to baking a cake or boiling an egg. Thermosetting are materials such as aminos, casein, epoxies, phenolics, polyesters, silicones, and polyurethanes.

Note:
Thermoforming is a process where a plastic sheet is heated, formed in a mold, and then trimmed. Thermoforming uses Thermoplastic materials.
yo mamma i dont know
It is a thermosetting polymer
thermoforming plastic is completley the oppisite of thermosetting!
Polyethylene is a thermoplastic polymer.
Polyvinyl chloride is a thermoplastic polymer.
thermosetting plastic becomes hard when heated and deteriorates by excessive cross linking and thermoplastic becomes soft and can be moulded into any shape.
Thermosoftening is when the bonds between molecules in a plastic are weak so that the plastic can easily soften. Thermosetting is when the bonds are strong so that the plastic can only be softened once and when it is, that is the only time that you can shape it.
Thermoforming.
Vacuum forming is one of the most common methods of processing plastic. The vacuum forming process involves heating a sheet of plastic until it is soft.
Polystyrene is a very poor conductor of heat. This is why its used as an insulator in some products.
simple polymer are define as themosofning plastic where as long chain polymer define as thermosetting plastic
