Polymers

Different polymers have different properties. They relate to the structure of the polymer and means they have lots of uses.

POLYETHENE:

  • Light, flexible, easily moulded, can be printed on
  • used to make plastic bags (flexible and light) 
  • used to makes containers (easily moulded)

POLYSTYRENE:

  • Light, poor conductor of heat
  • used for insulation (poor conductor of heat)

POLYESTER

  • Lightweight, waterproof, tough, can be coloured
  • Used for clothing (can be made into fibres)
  • Used for bottles (lightweight and waterproof)

Polymers like PVC are made of tangled, long chain molecules

The atoms are held together with STRONG COVALENT BONDS
