Polyvinyl Chloride (PVC)
This is one of the world's most widely used polymers. By itself it is quite
rigid and used in construction materials such as pipes, house siding, flooring.
Addition of plasticizers make it soft and flexible for use in upholstery, electrical
insulation, shower curtains and waterproof fabrics.
Polystyrene is transparent but rather brittle, and yellows under UV light. Widely
used for inexpensive packaging materials and "take-out trays", foam "packaging
peanuts", CD cases, foam-walled drink cups, and other thin-walled and moldable
Nylon has a fascinating history, both scientific and cultural. The common form Nylon
6.6 has six carbon atoms in both parts of its chain; there are several other kinds.
Nylon 6.6 has good abrasion resistance and is self-lubricating, which makes it a
good engineering material. It is also widely used as a fiber in carpeting, clothing,
and tire cord.
Polypropylene is used alone or as a copyolymer, usually with ethylene. These polymers
have an exceptionally wide range of uses — rope, binder covers, plastic bottles,
staple yarns, non-woven fabrics, electric kettles. When uncolored, it is translucent
but not transparent.
Polyurethanes are the single most versatile family of polymers. Their major use
is in plastic foams for thermal insulation, adhesives, synthetic fiber, but a very
large number of other applications, including paints and varnishes and plastic wheels
used in fork-lift trucks, shopping carts and skateboards.
Polyethylene is probably the polymer we see most in daily life. Polyethylene is
the most popular plastic in the world. Its primary use is within packaging(plastic
bag, plastic films, geomembranes, containers including bottles ) and children’s
They are easily worked, molded, and thermoformed. Because of these properties, polycarbonates
find many applications. Polycarbonate, or specifically polycarbonate of bisphenol
A, is a clear plastic used to make Compact discs, lightweight eyeglasses, shatterproof
glass. A balance of useful features including temperature resistance, impact resistance
and optical properties position polycarbonates between commodity plastics and engineering
