Properties and uses of different types of plastics
The seven most common and popularly used plastics are
Acrylic or Polymethyl Methacrylate (PMMA)
Polyethylene Terephthalate (PETE or PET)
Polyvinyl Chloride (PVC)
Properties of plastics
Plastics are generally low cost, easy to manufacture, durable, strong for their weight, electrically and thermally insulative, and resistant to shock, corrosion, chemicals, and water.
Uses of plastics
Plastics are used to make bicycle helmets, child safety seats and airbags in automobiles. They're in the cell phones, televisions, computers and other electronic equipment that makes modern life possible. They're in the roofs, walls, flooring and insulation that make homes and buildings energy efficient.
Polyethylene Terephthalate (PET) sometimes absorbs odours and
flavours from foods and drinks that are stored in them. Items
made from this plastic are commonly recycled. PET(E) plastic is
used to make many common household items like beverage
bottles, medicine jars, rope, clothing and carpet fibre.
Polyvinyl Chloride is sometimes recycled. PVC is used for all
kinds of pipes and tiles, but is most commonly found in plumbing
pipes. This kind of plastic should not come in contact with food
items as it can be harmful if ingested.
High-Density Polyethylene (HDPE) products are very safe and are not
known to transmit any chemicals into foods or drinks. HDPE
products are commonly recycled. Items made from this plastic
include containers for milk, motor oil, shampoos and conditioners,
soap bottles, detergents, and bleaches.
