  1. PLASTIC Group 3 3-2

  2. Plastic • Plastic is a synthetic or semisynthetic organic solid materials suitable for the manufacture of industrial products. Plastics are typically polymers of high molecular weight, and may contain other substances to improve performance or reduce costs.

  3. Plastic • For decades one of the great appeals of plastics has been their low price. Yet in recent years the cost of plastics has been rising dramatically. A major cause is the sharply rising cost of petroleum, the raw material that is chemically altered to form commercial plastics.

  4. Types of Plastic & Their Uses • Polypropylene (PP) Food containers, appliances, car fenders (bumpers). • Polystyrene (PS) Packaging foam, food containers, disposable cups, plates, cutlery, CD and cassette boxes. • High impact polystyrene (HIPS) fridge liners, food packaging, vending cups. • Acrylonitrile butadiene styrene (ABS) Electronic equipment cases (e.g., computer monitors, printers, keyboards), drainage pipe.

  5. Types of Plastic & Their Uses • Polyethylene terephthalate (PET) carbonated drinks bottles, jars, plastic film, microwavable packaging. • Polyester (PES) Fibers, textiles. • Polyamides (PA) (Nylons) Fibers, toothbrush bristles, fishing line, under-the-hood car engine mouldings. • Polyvinyl chloride (PVC) Plumbing pipes and guttering, shower curtains, window frames, flooring.

  6. Types of Plastic & Their Uses • Polyurethanes (PU) cushioning foams, thermal insulation foams, surface coatings, printing rollers. (Currently 6th or 7th most commonly used plastic material, for instance the most commonly used plastic found in cars). • Polycarbonate (PC) Compact discs, eyeglasses, riot shields, security windows, traffic lights, lenses. • Polyvinylidene chloride (PVDC) (Saran) Food packaging. • Polyethylene (PE) Wide range of inexpensive uses including supermarket bags, plastic bottles.

  7. Types of Plastic & Their Uses • Acrylonitrile butadiene styrene • Polyethylene terephthalate • Polyvinyl chloride • Polypropylene • Polystyrene
