Polymerzzzz

?

Polymers are made from crude oil which is a finite resource meaning it will run out and therefore plastic is not sustainable or good for the planet.

General properties of polymers include:

  • lightweight
  • waterproof
  • can be coloured
  • impact resistant
  • good strength to weight ratio

There are three different types of polymers:

  • thermosetting
  • thermoplastic
  • elastomers

Thermoset Polymers

They cannot be reheated or remoulded meaning they are not sustainable and damaging to the environment

Examples include:

  • urea formaldehyde - used for electrical fittings
  • epoxy resin

Thermoplastics

These have Van der Waals bonds meaning they can be reheated and remoulded…
