Transcript

  • 1.  
  • 2.
    • The history of plastics goes back more than 100 years.
    • Their usage over the past century has enabled society to make huge technological
    • advances to take us towards the new Millennium.
    • Pre-20th Century Although we think of plastic as a modern invention, there have
    • always been "natural polymers" such as amber, tortoiseshell and horn.
    • These materials behaved very much like manufactured plastics and were often put
    • to similar uses to today's materials - for example, horn, which becomes transparent
    • and pale yellow when heated, was used to replace glass in the 18th century.
  • 3.
    • It was the game of billiards that provided the unlikely cause for its eventual
    • commercial success.
    • The American Hyatt brothers were attempting to develop a substitute for the ivory
    • billiard ball and in so doing came up with a process for manufacturers using a
    • nitrate cellulose composition.
    • Celluloid was thus born and was patented in 1870 .
  • 4.
    • Bakelite - a hard, dark plastic - was discovered by Leo Baekeland, a Belgian-born
    • chemist in 1907 and was the first truly synthetic plastic to be patented.
    • Bakelite brought plastics into consumers' lives in a variety of ways.
    • Its excellent insulating properties made it an ideal material for hairdryers, radio
    • cabinets, ashtrays and cameras.
  • 5.
    • In 1922 a German chemist, Hermann Staudinger, made a discovery which would
    • change the whole face of the plastics industry.
    • Through working with synthesized rubber, he found that plastics are made from
    • chains of thousands of molecules linked together, known as "superpolymers" - a
    • find which prompted the invention of many new plastics.
    • 1922 - first spectacles molded in cellulose acetate (in France)
  • 6.
    • World War II meant a huge boost for plastics.
    • The production of plastics which are still used widely today - such as polyethylene,
    • polystyrene, polyester, PET and silicones - all grew during the wartime period.
    • Nylon, the first totally man-made fiber, had been discovered at the end of the 20s,
    • but was not put to great use until the 40s.
  • 7.
    • PVC really took off during this decade and into the 1950s.
    • The 1950s The 50s saw the growth of decorative laminates such as Formica, first
    • popular in the United States where they were used widely in espresso bars and
    • dinettes.
    • A first for the car industry: 1956 saw the major use of plastics in car body design
    • when the roof of a Citroen DS was made from unsaturated polyester reinforced
    • with fiberglass.
  • 8.
    • During the 50s plastics became a major force in the clothing industry.
    • Polyester, Lycra and nylon were easy to wash, needed no ironing and were often
    • cheaper than their natural alternatives and, as a result, were hugely popular with
    • consumers tired of the tyranny of housework.
  • 9.
    • 1960 saw the first use of PVC to bottle mineral water.
    • The first domestic items made from molded polypropylene were developed from
    • 1963 onwards - including combs, lemon squeezers and bottle stoppers.
  • 10.
    • The explosion in global communications during the 80s and 90s has been made
    • largely possible through the use of plastics.
    • Equipment such as computers, fiber optic cables and telephones all use plastics
    • widely in their design to provide strength, light weight, insulation and flexibility.
    • Transport also has started using plastics more widely.
