Why are So Many Things Made
of Plastic?
|
|
Resistant
to Chemicals
Plastics can be very resistant to
chemicals. Consider all the corrosive
cleaning fluids in your home. Most
of them come in plastic containers.
|
|
Electrical
and Thermal Insulator
Plastic won't pass an electric current,
which is why electric wiring, outlets,
and appliances tend to be covered
in plastic.
Plastic also doesn't conduct heat
very well, making it useful for keeping
things warm, or cold.

Light
Weight but Strong
Plastic is used in the frame structure
of space stations. It's also used
to make key components for automobiles.
One of
the big reasons is the fact that plastic
can be made strong, but light and
doesn't rust or corrode.

Can
Take Many Forms
Plastics can be made into all kinds
of shapes. From thin fibers to bottles
or dashboards for cars. Some plastics
can
be stretched into sheets, while others
can be puffed up to make cups.
|
|
Can
Perform Many Jobs
By altering a plastic's chemical recipe
you can make it perform a specific
job, from keeping food fresh to stopping
bullets. This is what really sets
plastic apart from other materials.
