CHEMISTRY IN PLASTIC The majority of plastics are composed of polymers of carbon and hydrogen alone or with oxygen, nitrogen, chlorine or sulphur in the backbone. Some Common plastics are : Polypropylene (PP) - Food containers, appliances, car fenders (bumpers) Polystyrene ( PS) - Packaging foam, food containers, disposable cups, plates, CD boxes. High impact polystyrene (HIPS)- Fridge liners, food packaging, vending cups. Acrylonitrile butadiene styrene (ABS)- Electronic equipment cases as computer parts, drainage pipe etc. Polyethylene T erepthalate (PET)- Carbonated drink bottles, jars, plastic films, microvable packaging. Polyester (PES)- Fibres , textiles . Polyamides (PA) (Nylons)- Fibres , toothbrush bristles, fishing line, under the hood car engine mouldings . Poly Vinyl Chloride(PVC )- Plumbing pipes and guttering, shower curtains, window frames. Polyurethanes (PU)- Cushioning foams, thermal insulation foams, surface coatings, printing rollers. Polycarbonate (PC)- Compact discs, eyeglasses, security windows, traffic lights, lenses. Poly vinyldene chloride (PVDC)- Food packaging Polyethylene(PE)- Wide range of inexpensive uses including super market bags, plastic bottles Polycarbonate/Acrylonitrile Butadiene Styrene(PC/ABS)- Car interior and exterior parts .
