Polymers

1
Polymers

• . A polymer is a substance which is composed of
  molecules which contain large molecular masses
  consisting of repeating structural units, or
  monomers, attached by covalent chemical bonds.

2
Rubber

• both rubber and plastic are each considered to be
  both synthetic and natural materials

3
Rubber and Plastic Bonding

• If a tire was crossed with a plastic milk
  bottle, together they could form a tire based
  composite which would be suitable for impact
  barriers, earth retainers, and curb blisters.
  This would create a tire that was cheap and able
  to absorb energy much better.

4
Vulcanization

• Known as the curing of rubber.
• This results in the bouncy rubber molecules
  becoming cross linked to a greater or maybe a
  lesser extent. This makes the bulk material
  harder, more durable, as well as more resistant
  to chemical attack.
