| Thermoplastics: PC (properties) | -Good chemical resistance -Expensive -Very tough |
| Thermoplastics: PC (uses) | -Hairdryers -Protective shields |
| Thermosets: Epoxy resins (properties) | -High strength when reinforced with fibres -Good chemical resistance -Good wear resistance |
| Thermosets: Epoxy resins (uses) | -Surface coating -Encapsulation of electronics |
| Thermosets: Melamine formaldehyde (properties) | -Rigid -Good strength and hardness -Scratch resistant -Can be coloured |
| Thermosets: Melamine formaldehyde (uses) | -Tableware -Decorative laminates |
| Thermosets: Polyester resins (properties) | -Rigid -Brittle -Good heat resistance -Good chemical resistance |
| Thermosets: Polyester resins (uses) | -Casting -Used in GRP |
| Thermosets: Urea formaldehyde (properties) | -Rigid -Hard -Good strength -Brittle -Heat resistant -Good electrical insulator |

| Biodegradable Plastics: PLA | -Transparent -Similar to polyethylene and polypropylene Eg. Medical equipment and packaging |
| Biodegradable Plastics: Biopol | -Harvested from bacteria grown in cultures -Most popular type is PHB and is used in packaging due to its similarities to polypropylene Eg. Used in medicine implants because of its ability to dissolve over time |
| Biodegradable Plastics: Oxo degradable | These polymers have additives that promote short degradation times, this helps the polymer break down into a fine powder that is more readily digestible |
| Biodegradable Plastics: Photodegradable | These polymers break down when exposed to light |
| Biodegradable Plastics: Water soluble | Eg. Products such as liquid detergents in pouches that dissolve when in contact with water |
