Where do polymers come from? • What is the raw material that is used

Where do polymers come from? • What is the raw material that is used to make polymers? • What are the environmental impacts of manufacturing polymers? • What are the environmental impacts of the disposal of polymers? • What can we do to reduce these environmental impacts?

The two families of Polymer • Thermoforming • Can be reheated and reformed over

The two families of Polymer • Thermoforming • Can be reheated and reformed over and over again • Recyclable • Thermosetting • Can only be heated and formed once • Non recyclable

Examples of Thermoforming Polymers • Acrylic (PMMA) Hard , stiff and shiny • Poly

Examples of Thermoforming Polymers • Acrylic (PMMA) Hard , stiff and shiny • Poly Vinyl Chloride (PVC) Quite brittle, cheap, durable • Polypropylene – Quite tough, flexible, easily coloured • Polyethylene (PET) – Light, strong, tough • High Impact Polystyrene (HIPS) – Rigid, fairly cheap

Examples of Thermosetting Polymers • Epoxy Resin (ER) – Rigid, durable, corrosion resistant, good

Examples of Thermosetting Polymers • Epoxy Resin (ER) – Rigid, durable, corrosion resistant, good electrical conductor • Melamine Formaldehyde (MF) – Strong, scratch resistant • Urea Formaldehyde (UF) – Hard, brittle, good electrical insulator • Phenol Formaldehyde (PF)– Hard, heat resistant, easily moulded • Polyester Resin (PR) – Hard, stiff, cheap, good electrical insulator

Research each of the different Polymers • Find out which products they are used

Research each of the different Polymers • Find out which products they are used to make • Why are their properties suitable for these uses • Try to give some examples of products that could be made from each of these materials which are not currently. • Write up your findings in your green book. • You can use your Blue book or www. technologystudent. com
