CLASSIFICATION OF PLASTICS

- THERMOPLASTICS

            When we heat them, they become soft, which allows them to be formed into different shapes.
            The heated and cooling process can be repeated many times.

                                 - PVC
                                 - PS
                                 - PE
                                 - PP
                                 - Methacrylate
                                 - Teflon
                                 - Cellophane
                                 - Polyamide (Nylon)


- THERMOSETTING  PLASTICS

             When heated, they become soft and can be shaped. When cooled, they cannot be remoulding by applying heat.

                               - Polyurethane
                               - Phenolic resins
                               - Melamine
                               - Polyester resins

- ELASTOMERS

                    Made by vulcanization: mixing sulphur and rubber, and heating to 160ºC.

                              - Natural Rubber
                              - Synthetic rubber
                              - Neoprene
                              - Silicone
