- - - - Properties: is strong, is waterproof and durable.
      - Uses: tubes and pipes, shoe soles, gloves, waterproof clothing, hosepipes.
    - - Hard
        
        Properties: is transparent, and it can be coloured.
        
        Uses: CD cases, coat hangers, dairy products containers, egg boxes.
      - Expanded (porexpan)
        
        Properties: is porous and soft.
        
        Uses: packaging, thermal and acoustic insulation.
    - - High density (HDPE)
        
        Properties: is rigid, resistant and transparent.
        
        Uses: domestic utensils (buckets, containers) toys.
      - Low density (LDPE)
        
        Uses: transparent packaging film, bags, cups and plates.
        
        Properties: is soft, light and transparent.
    - - Properties: is flexible, resistant to chemicals and it has a hard surface.
      - Uses: bottles and containers, ropes, bags.
    - - Properties: is transparent.
      - Uses: car headlights, windows, illuminated signs, goggles, watches.
    - - Properties: is non-stick, and it has a high resistance temperature.
      - Uses: kitchen utensils, paints, aircraft and rocker exteriors.
    - - Properties: is transparent, flexible, resistant, shiny amd adhesive.
      - Uses: packaging, wrapping.
    - - Properties: is translucent, shiny, resistant, flexible and waterproof.
      - Uses: fabrics, toothbrushes, tennis racket strings.
  - - - Properties: is shock and resistant, it has dark colours, is an electric insulator and a heat resistant.
      - Uses: kitchen utensil handlers, covers for electrical appliances, electric plugs and switches.
    - - Properties: is light, hard and resistant, tasteless and odourless, and is a thermal insulator.
      - Uses: small electrical objects, thermal and acoustic insulation, kitchen surfaces, plates and food containers.
    - - Properties: porous and flexible; soft and dense; elastic and adhesive.
      - Uses: foam rubber for cushions, sponges, thermal and acoustic insulation, glues and varnishes.
    - - Properties: is a heat resistant, is reinforced by fibre-glass for strength and rigidity.
      - Uses: crash helmets, bodywork for cars and boats, fishing rods.
  - - - Properties: resistant to chemicals
      - Uses: tyres, steering wheels, shock absorbers, tubes, pipes, gloves, mattresses.
    - - Properties: harder, more resistant than synthetic rubber, waterproof.
      - Uses: diving suits, hosepipes, gloves.
    - - Properties: is resistant and inert.
      - Uses: thermal and electrical insulation. mattresses, tyres.
- - - - We close the mould and blow pressurised air into it, so that the plastic adheres to the sides of the mould and takes its shape.
      - When the object is cold, we remove it from the mould.
      - We put a tubular-shaped piece of plastic into a hollow moulds which has the same shape as the object that we want to make.
      - Used to form: hollow objects (bottles, flasks)
    - - The outer part of the cavity mould, shaped the same, is closed to compress the material inside. We then heat it and it becomes more soft and malleable.
      - The plastic adapts to the shape of the cavity between the two parts of the mould.
      - We put thermostable plastic, which can be in granular form. into the base of a cavity mould.
      - We extract the object when the plastic has cooled and solidified.
      - Used to form: containers, machine bodywork, electrical appliances.
    - - When the material has cooled and solidified, we extract it from the mould.
      - Used to form: buckets, containers, vehicle and aircraft components.
      - We inject melted thermoplastic into a mould.
- - - - Acrylic cement: liquid, used mainly with PVC and polystyrene.
      - Contact adhesives: liquid, work instantly after appiying to both surfaces, used with all types of plastics.
      - Resins with two components: liquid, high water resistance.
