4 LDPE (Low Density Polyethylene)

  1. Low density polyethylene is one of the safe plastics.
  2. It is commonly used for making squeezable bottles, frozen food, bread bags, shopping bags, clothing, carpet, and some food wraps. 
  3. Such plastics are generally recycled and used for making of compost bins, floor tiles, paneling, trash can liners and cans, shipping envelopes etc. 

5 – PP (Polypropylene)

  1. Phillips Petroleum chemists J. Paul Hogan and Robert L. Banks first polymerized propylene in 1951.
  2. Polypropylene is the second most important plastic with revenues expected to exceed US$145 billion by 2019.
  3. The sales of this material are forecast to grow at a rate of 5.8% per year until 2021
  4. It is the most globally accepted and most safest plastic material that can be used in day to day life.
  5. It is used for making of yogurt containers, syrup bottles, ketchup bottles, and medicine bottles,Plastic chairs,diagnostic sample collection containers.
  6. Such plastics are used for the management of hernia and used as mesh to prevent the prolapse.  
  7. It is used for structural material in hobbyist radio control model aircraft
  8. It can be recycled and used for making of signal lights, bins, ice screapers etc.

6 – PS (Polystyrene)

  1. Polystyrene was discovered in 1839 by Eduard Simon from the resin of the Turkish sweetgum tree.
  2. Polystyrene is one of the most widely used plastic and it produced in several billion kilograms per year.
  3. It is clear in nature having very low melting point. It is resistant to acids and alkalies but dissolves easily in many chlorinated solvents, and many aromatic hydrocarbon solvents.
  4. Polystyrene is a long chain hydrocarbon and chemically known as (C
    8
    H

    )
    n.
  5. Polystyrene is Styrofoam, the most dangerous and environment unfriendly plastic in nature. Discarded polystyrene does not biodegrade for hundreds of years and is resistant to photolysis.
  6. It is commonly used for manufacturing the egg cartons, meat trays, and disposable plates and cups.
  7. It is harmful for the body and creates many health hazards. 
  8. If can't be brunt or can be heated. No burning or heating it became more dangerous for the health and nature.
  9. It is highly flammable and causes sever accidental damages.
  10. Generally such kind of plastics are difficult to recycle and no program supports such plastic for recycling and manufacturing. 

7 – Other, Miscellaneous Types of Plastic
