    Study Notes

    Materials: The Plastic

    • Plastic materials have allowed us to avoid using pig hair to comb our hair and have helped prevent the extinction of elephants.
    • Plastic is present in objects, clothes, paint, adhesives, etc. due to its interesting properties and low cost.
    • Plastic is made from fossil fuels, and when we run out of these fuels, the price of plastic will increase.
    • Celluloid was the first plastic made in the mid-19th century, and bakelite was the first plastic used massively in the industry in the early 20th century.
    • Plastics are organic substances made of polymers, which are macromolecules formed by the combination of carbon, oxygen, hydrogen, and more elements.
    • Plastics are obtained from fossil fuels through the process of polymerization in petrochemical plants.
    • Plastics have various properties such as lightness, waterproofness, thermal insulation, electrical insulation, non-corrosiveness, chemical resistance, tenacity, and photodegradability.
    • Plastics have advantages such as lightness, low melting temperatures, and thermal insulation, but they also have disadvantages such as non-biodegradability, toxicity, and difficulty in recycling.
    • The 3 R's of plastics are: Reduce the use of plastic, Reuse plastic before throwing it away, and Recycle plastic by properly separating and disposing of it in recycling containers.
    • Plastic has lowered manufacturing prices, improved science and technology, and contributed to our quality of life.
    • Plastic was invented to replace ivory, which was highly valued and obtained from the fangs of elephants, leading to their endangerment.
    • Plastic has helped prevent the extinction of elephants by providing an alternative to ivory.
