Design & Technology: GraphicsGCSE Created by: ellieCreated on: 02-05-12 09:56 Thermoplastics Can be moulded by heating and can be re-molded if heated again 1 of 13 Acetate (Cellulose acetate) Flexible, hard, shiny and transparent/translucent Thin sheets for overhead projectors and for packaging where the product must be seen Easy to print on Made mostly from wood= more sustainable 2 of 13 Polypropylene Tough, strong and flexible Can be made with a 'living hinge' (therefore all one piece) Lunch boxes, chairs, textiles and car parts 3 of 13 High Impact Polystyrene rigid, varied colours and thicknesses boxes for products vacuum forming fairly cheap 4 of 13 Polyvinyl Chloride (PVC) Cheap and durable easy to print on quite brittle Used for blister packaging (pills) vinyl records, insulation, or electrical wires etc. 5 of 13 Plastics For Modelling Materials These next few plastics are not very strong but are easy to cut and shape. That makes them good modelling materials- to see ideas in 3d. 6 of 13 Corrugated Plastic Sheet Lightweight, rigid and weather proof Made from polypropylene stiff but can be bent in to shapes- good for flat surfaces & square edges estate agent signs or student folders for example. 7 of 13 Expanded Polystyrene foam (STYROFOAM) Lightweight Can be shaped with a knife Can be quite crumbly Dense structure (styrofoam) Good for models but need to be filled in order to paint. 8 of 13 Machining Foam more compact than expanded polystyrene- can be worked on using machine tools Make detailed pieces which can be painted Used for architectual models 9 of 13 Acrylic Stiff and brittle Used to make signs and small 2D and 3D forms 10 of 13 Cellophane Tough, hard, stiff lightweight transparent Non-flammable Wrapping around products=protection 11 of 13 Polythene Hard, stiff able to be sterilised used for bottles and shrink wrapping 12 of 13 Acrylonitrile butadiene styrene (ABS) Strong, hard, lightweight and durable Good finish resistant to chemicals makes tubes and structures. Also can be corrugated. 13 of 13
