Plastics - Coggle Diagram

- - - - polyvinyl chloride (PVC)
      - Polystyrene (PS)
        
        hard
        
        expanded (porexpan)
      - Polythene (PE)
        
        high density (HDPE)
        
        low density (LDPE)
      - polypropylene (PP)
      - Polymethyl methacrylate (PMMA)
      - Teflon (Fluorocarbon)
      - Cellophane
      - Nylon (PA or Polyamide)
- - - - are obtained directly from raw vegetable materials
        
        for example: latex, cellulose, etc
        
        latex
    - - Are made from compound extracted from:
        
        petroleum, natural gas and carbon.
        
        petroleum
        
        The transformation of these raw materials and compounds into plastics is called polymerisation
- - - - mechanical: malleability, ductility, mechanical resistant
        
        acoustic: acoustic insulation
        
        electrical: electrical insulation
        
        termal: termal insulation
        
        Other properties: Low density, impermeability
    - - strength, elasticity, rigidity, flexibility
        
        elastic
- - - - We apply chemical processes to make new materials from the original components of plastic residues
    - - We make new products from plastic granules, the process has five stages:
        
        seperation and crushing
        
        floating
        
        agglutination
        
        extrusion
        
        pelletising

    - - we can incinerate plastics and the energy that is produced is used in industry, for heating or producing electricity
