Study Notes

  • Plastic materials have low thermal conductivity due to irregularities in their molecular structure.
  • Copper conducts heat 2,400 times faster than plastic.
  • Polystyrene foam, which is 98% air, is an even better insulator.
  • Polycarbonate is a transparent and strong plastic commonly used as a substitute for glass.
  • Polyethylene is a lightweight and flexible plastic with high resistance to heat and chemicals.
  • PET is a commonly recycled plastic used for food and beverage packaging.
  • PMMA, also known as acrylic glass or Plexiglas, is a hard and transparent plastic with a wide range of uses.
  • Plastics are used in a variety of products such as CD/DVDs, combat shields, bottles, furniture, and more.
  • Plastics have different properties such as rigidity, flexibility, translucency, and resistance to heat and chemicals.
  • Plastics can be recycled.
