  1. THERMOPLASTICS (separate chains of polymers)
    1. STRUCTURE
      1. THERMOPLASTIC MATERIALS (plastics that are softened by heating, can be formed and melted as many times as we like)
        1. POLYRTHYLENE (PE) most common type of plastic. Offers good chemical resistance. Non-toxic, sustainable for food packaging
          1. POLYSTYRENE (PS) very lightweight, transparent plastic. Expanded polystyrene is widely used in packiging and for heat insulation.
            1. PVC (POLYNINYL CHLORIDE) highly resistant to abrasion and impact
              1. POLYPROPYLENE (PP) plastic easy to model and dye. Resistant to solvents and splintering
                1. PET (POLYETHYLENE TEREPHTHALATE) sustainable for food use, this plastic is completely recyclable, transparent and easy to dye
                  1. >
                  2. TEFLON highly resistant to chemicals and high temperatures. Excellent non-stick properties.
                    1. POLYCARBONATE (PC) highly resistant to impact and heat. Good optical transparency.
                      1. NYLON: exceptionally strong and elastic. Excellent toughness, abrasion resistance, easy to wash and to dye
                        1. >
                    2. THERMOSERS (CRISS-CROSSED POLYMER CHAINS)
                      1. STRUCTURE
                        1. THERMOSET MATERIALS (plastics can be shaped using heat, but once they've been formed they can't be re-melted to create different forms)
                          1. MELAMINE resistant to high temperatures and chemicals. Easy to clean.
                            1. BAKELITE a hard and brittle, dark plastic that withstands heat very well
                              1. >
                              2. POLYESTER RESINS rigid and brittle, usually strenghned with fibreglass
                                1. PHENOLIC: superior mechanical strenght, heat resistance. Resistance against various solvents, acid and water.
                                  1. >
                              3. ELASTOMERS (coiled polymer chains)
                                1. STRUCTURE
                                  1. ELASTOMER MATERIALS (very flexible materials thet recover their shape and dimensions when external forces stop acting on the them. They degrade easily with the heat and can't be re-melted once they've been once formed)
                                    1. RUBBER: can be natural or synthetic. It's elastic.
                                      1. NEOPRENE: flexible, insulated and waterproof.
                                        1. >
                                        2. SILICON: heat resistant
                                          1. POLYURETHANE: resistant to water, electrical properties
                                            1. >
