- Thermosets
- PUR (Polyurethane)
- Resistant to abrasion. High impact resistance. Flexible at low temperatures. Radiation resistant. Can be made flame resistant.
- Uses - insulating foams, mattresses, adhesives, car parts, flooring, synthetic fibres.
- Bakelite
- Moulded very quickly. Smooth. They retain their shape. Electricity resistant. Low conductivity.
- Uses - electrical insulators, plasticware, old telephones and radios.
- Duroplast
- Lightweight. Strong.
- Uses - car parts, suitcases.
- Urea-formaldehyde
- Rigid. Hard. Good strength. Brittle. Heat-resistant. Good electrical insulator.
- Uses - electrical fittings, adhesives.
- Melamine formaldehyde
- Rigid. Good strength and hardness. Scratch-resistant. Can be coloured.
- Uses - tableware, decorative laminates for work surfaces.
- Epoxy resin
- High strength when reinforced with fibres (GRP - glass-reinforced plastic). Good chemical and wear resistance.
- Uses - surface coating, encapsulation of electronic components, adhesives.
- PI (Polyimide)
- Thermal stability. Lightweight. Flexible. Resistant to heat and chemicals.
- Uses - insulation, bearings, sockets, filters, medical tubing.
- Polyester resin
- Rigid. Brittle. Good heat and chemical resistance.
- Uses - casting, used in glass-reinforced plastic (e.g. boat hulls, car body parts)
- PUR (Polyurethane)
