Thermoforming and Thermosetting Polymers - Coggle Diagram
Thermoforming and Thermosetting Polymers
Thermoforming
Melts upon heating allowing it to be reshaped due to weak intermolecular forces
Acrylic
Shop signs, car lights, baths
HIPS (High - impact polystyrene)
Toys, yoghurt pots, fridge linings
BIOPOL
Disposable cutlery, packaging, surgical stitches
PVC
Pipes, window frames, cable insulation
Thermosetting
Does not melt, permanently set and chars upon extreme heat due to strong covalent bonds
Urea formaldehyde
Electrical plugs, sockets, switches
Polyester resin
Boat hulls, car body panels, casting
Properties
Fusibility - Ability to be melted by heat and change into a liquid state
Mouldability - ability to be shaped into a desired form by heat or pressure
Recyclability - ability to be processed and reused
Heat resistance - ability to withstand significant temperatures
