Types of plastics

Types of plastics. Polyethene Polystyrene PVC. Plastics are made from crude oil. Crude oil is unrefined oil – it needs to be purified before it can be used. Crude oil is made of hydrocarbons which can be separated into fractions of different boiling points.

Presentation Transcript

  1. Types of plastics • Polyethene • Polystyrene • PVC

  2. Plastics are made from crude oil • Crude oil is unrefined oil – it needs to be purified before it can be used.

  3. Crude oil is made of hydrocarbons which can be separated into fractions of different boiling points

  4. Simple hydrocarbons are separated from oil. • These are called monomers • These monomers join together to form POLYMERS • All plastics are made of polymers

  5. Everyday applications of plastics • Electrical insulation • Food containers • Packaging • Pipes

  6. Relating the properties of plastics to their use

  7. What property does this plastic have that makes it suitable for its job?

  8. Non-biodegradable plastics • Non-biodegradable plastics do not break down in nature

  9. Non bio degradable

  10. Biodegradable plastics

  11. Impact on the environment • Small pieces of plastic can get eaten by animals and birds on land and by fish in the sea which causes choking. • In the sea many fish can get trapped in plastic bags. • Plastic gives out an enormous amount of poisonous smoke when burnt which can be fatal in a house fire.
