1 Plastics and their uses High Density Polythene Low Density Polythene Polyvinyl Chloride Polystyrene Nylon Cellulose Acetate Acrylic Polypropylene ABS Epoxy Resin Melamine Formaldehyde Polyester Resin Glass Reinforced Plastic Carbon Fibre Plastics Elastomers

2 All Plastics fall within two groups Thermoplastics High Density Polythene Low Density Polythene Polyvinyl Chloride Polystyrene Polypropylene Nylon ABS Cellulose Acetate Acrylic Elastomers Epoxy Resin Polyester Resin Glass Reinforced Plastic Carbon Fibre Plastics Melamine Formaldehyde Thermosetting Plastics

3 High Density Polythene Properties: Tough, Feels Waxy, Resistant to chemicals. HDPE is used for Buckets, Basins, Bottles, Containers and is extensively used in both Blow Moulding and Injection Moulding processes Back

4 Low Density Polythene Properties: Soft, Flexible good electrical insulator. Most LDPE application is film based. Industry uses also include wire and cable coating, injection and Blowmolding. is used for Plastic bags, Bottles Back

5 Polyvinyl Chloride Properties: Rigid, Weather resistant. PVC is used for Gutters, Window frames & Drainpipes. It is often used in the Extrusion process. Back

6 Polystyrene Properties: Soft, Lightweight, Good insulator Polystyrene is used extensively in the packaging industry. It is also used to insulate buildings Back

7 Nylon Properties: Hard, tough, rigid. Self-lubricating. Resistant to petrochemicals. Nylon is used for Gear wheels, Bearings, Curtain rails packaging, film, clothing, Back

8 Cellulose Acetate Properties: Hard, tough, flexible Cellulose Acetate is one of the older plastics and is used for film making & Packaging Back

9 Acrylic Properties: Stiff, Hard, Brittle, Scratches easily Acrylic is used for Baths, Signs, Lighting, Windows (Perspex) display stands Back

10 Polypropylene Properties: Rigid, Good fatigue resistance, Good chemical resistance Polypropylene is one of the more flexible plastics and is used for Plastic hinges, Crates, Rope & Yarn Back

11 Acrylonitrile Butadiene Styrene Properties: Strong and Tough. Impact resistant, Scratch resistant, Chemical resistant. Comes in a wide range of colours. ABS is used extensively for injection molding, Typical products would be Car bumpers, Kitchen ware, Cases, helmets etc Back

12 Epoxy Resin Properties: Epoxy Resin is generally used as an adhesive of as a liquid for casting Strong (when reinforced), Clear Back

13 Melamine Formaldehyde Properties: Melamine Formaldehyde commonly known as Formica is a composite material made from resin and layers of paper, Commonly used for kitchen worktops Clarity, Stability to heat, light, chemicals, abrasion and fire Back

14 Polyester Resin Properties: Polyester Resin is primarily used with Glassfiber to form GRP however it can be used on its own for casting and embedding Brittle, Clear Back

15 Glass Reinforced Plastic Properties: Glass Reinforced Plastic (GRP) is a composite material made from Resin and Glass fiber sheet. This combination produces a lightweight yet extremely strong material and is used everywhere from Speed boat hulls to aircraft Very Strong, Lightweight Back

16 Carbon Fibre Plastics Properties: Carbon Fibre Plastics have an extremely strong strength to weight ratio and are often used for Sports Car bodywork, High end cycles, fishing rods etc Very Strong, Lightweight, flexible Back

17 Elastomers Properties: Elastomers are plastics with elastic properties, most ate capable of considerable deformation and will return to their original shape. Uses range from waterproof seals to foam padding Flexible, Waterproof Back
