Plastics 1 of 31 Name 5 types of plastics? 1/ PET 2/ HDPE 3/ PVC 4/LDPE 5/PP 6/PS 7/Acetate 8/Acrylic 2 of 31 what are the properties of PET? Excellent barrier, durable, lightweight 3 of 31 Uses of PET Fizzy drinks bottles 4 of 31 What are the properties of HDPE? Durable, lightweight, rigid 5 of 31 Uses of HDPE Flexible bottles (e.g washing up liquid), detergents 6 of 31 What are the properties of PVC? Protects products from moisture, strong, flexible, durable 7 of 31 Uses of PVC Toiletry packaging, water, fruit juices 8 of 31 What are the properties of LDPE? Tough, durable, lightweight, flexible 9 of 31 Uses of LDPE Cling film, milk/ribena carton coating 10 of 31 What are the properties of PP(polypropylene)? Durable, lightweight, very flexible 11 of 31 Uses of PP Yogurt, butter tubs, sweet wrappers 12 of 31 What are the properties of PS(polystyrene)? Durable, lightweight, rigid 13 of 31 Uses of PS Food packaging, egg cartons 14 of 31 What are the properties of Acetate? Thin, transparent, flexible 15 of 31 Uses of acetate Flexible, easily cut , windows on products 16 of 31 What are the properties of Acrylic? Wide range of colours available, rigid, brittle, heavy, glossy 17 of 31 Uses of acrylic Signage, point of sale, laser cut items 18 of 31 What are the two catergories for plastics Thermosetting plastics and Thermoplastics 19 of 31 What are thermosetting plastics? plastics which do not go back to their original shape when heated. 20 of 31 What are thermo plastics Plastics which can be reheated and remoulded 21 of 31 Name some general properties of polymers Can be formed, inexpensive, recyclable, available in colours, lightweight, durable, easy to print on 22 of 31 Why are the codes for all polymers around the world the same so that they can be easily recognised internationally and helps polymers from being sorted when being recyled 23 of 31 What happens when PVC (polyvinyl chloride) is incinerated? It produces HCL (hydrochloric acid) which is harmful to the environment 24 of 31 What is styrofoam typically used for? For block modelling and insulation 25 of 31 What colours does styrofoam come in? Blue and Pink 26 of 31 Why is styrofoam an excellent modelling material? It is easy to shape using normal hand tools and can be sanded to give a smooth finish and can be glued together to make different thicknesses 27 of 31 Why does styrofoam need to coated before spray painting? so that paint is applied on a smooth surface and also prevents the foam from melting or being damaged by the spray paint. 28 of 31 What is acrylic also known as? Perspex 29 of 31 What is a special property of acrylic compared to other polymers? It can withstand extreme weather conditions as it is chemical resistant and durable 30 of 31 what are some disadvantages of acrylic (perspex) ? It can scratch easily as well as snap as it is brittle 31 of 31
