List of Synthetic Polymers - Organic Polymers

Organic Polymers

The seven most common types of synthetic organic polymers, which are commonly found in households are:

  • Low Density Polyethylene (LDPE),
  • High Density Polyethylene (HDPE),
  • Polypropylene (PP)
  • Polyvinyl Chloride (PVC)
  • Polystyrene (PS)
  • Nylon, nylon 6, nylon 6,6
  • Teflon (Polytetrafluoroethylene)
  • Thermoplastic polyurethanes (TPU)
List of some addition polymers and their uses
Polymer Abbreviation Properties Uses
Low Density Polyethylene LDPE Chemically inert, flexible, insulator Squeeze bottles, toys, flexible pipes, insulation cover (electric wires), six pack rings, etc.
High Density Polyethylene HDPE Inert, thermally stable, tough and high tensile strength Bottles, pipes, inner insulation of coax cable, plastic bags, etc.
Polypropylene PP Resistant to acids and alkalies, High tensile strength Auto parts, industrial fibers, food containers, liner in bags, dishware and as a wrapping material for textiles and food
Polystyrene (thermocole) PS Thermal insulator. Properties depends on the form, expanded form is tough and rigid Petri dishes, CD case, plastic cutlery
Polytetrafluoroethylene PTFE Very low coefficient of friction, excellent dielectric properties, chemically inert Low friction bearings, non-stick pans, coating against chemical attack etc.
Polyvinylchloride PVC Insulator Pipe, fencing, lawn chairs, hand-bags, curtain clothes, non-food bottles, raincoats, toys, vinyl flooring etc.
Polychlorotrifluoroethylene PCTFE Stable to heat and thermal attacks, high tensile strength and non wetting valves, seals, gaskets etc.

Famous quotes containing the word organic:

    “When life has been well spent, age is a loss of what it can well spare,—muscular strength, organic instincts, gross bulk, and works that belong to these. But the central wisdom, which was old in infancy, is young in fourscore years, and dropping off obstructions, leaves in happy subjects the mind purified and wise.”
    —Ralph Waldo Emerson (1803–1882)
