Plastic Resin Polypropylene
Learn
the Basics of the Plastic Resin Polypropylene
by
Polypropylene
is a type of thermoplastic polymer resin.
It is
a part of both the average household and is in commercial and industrial
applications.
The
chemical designation is C3H6.
One
of the benefits of using this type of plastic is that it can be useful in
numerous applications including as a structural plastic or as a fiber-type
plastic.
History
The
history of polypropylene began in 1954 when a German chemist named Karl Rehn
and an Italian chemist named Giulio Natta first polymerized it.
This
led to a large commercial production of the product that began just three years
later. Natta synthesized the first syndiotactic polypropylene.
Everyday
Uses
The
uses of polypropylene are numerous because of how versatile this product is.
According
to some reports, the global market for this plastic is 45.1 million tons, which
equates to a consumer market use of about $65 billion.
It is
used in products such as the following:
· Plastic
parts - from toys to automobile products
· Carpeting
- in all forms of carpeting, area rugs and in upholstery
· Reusable
products - especially in containers and similar products
· Paper
- used in various applications for stationery and other writing bindings
· Technology
- commonly found in loudspeakers and similar types of equipment
· Laboratory
equipment - in virtually every aspect where plastics are found
· Thermoplastic fiber
reinforced composites
There
are a few reasons that manufacturers turn to this type of plastic over others.
Consider
its applications and benefits:
Benefits of Polypropylene
The
use of polypropylene in everyday applications occurs because of how versatile
this plastic is. For example, it has a high melting point compared
to similarly weighted plastics.
As a
result, this product works very well for use in food containers where
temperatures can reach high levels — such as microwaves and in dishwashers.
With
a melting point of 320 degrees F, it is easy to see why this application makes
sense.
It is
easy to customize, too. One of the benefits it offers to manufacturers is the
ability to add dye to it.
It
can be colored in various ways without degrading the quality of the plastic.
This is also one of the reasons it is commonly used to make up the fibers in carpeting.
It
also adds strength and durability to the carpeting. This type of carpeting can
be found effective for use not only indoors but also outdoors, where damage
from the sun and elements doesn't affect it as readily as other types of
plastics.
Other
benefits include the following:
· It
does not absorb water like other plastics.
· It
does not mold or otherwise deteriorates in the presence of bacteria, mold or
other elements.
· Newer
versions contain an elastic element to them. This gives them a rubber-like composition
and opens the door for new uses.
· It
is unlikely to shatter and will take significant damage prior to breaking,
though it is not as sturdy as other plastics such as polyethylene.
· It
is lightweight and very flexible.
Chemical Properties and Uses
Understanding polypropylene is
important because it is significantly different from other types of products.
It's
properties allow it to be effective in the use of material popular in everyday
use, including any situation in which a non-staining and non-toxic solution is
necessary.
It is
also inexpensive.
It is
an excellent alternative to others because it does not contain BPA.
BPA
is not a safe option for food packaging since this chemical has been shown to
leach into the food products. It has been linked to various health issues,
especially in children.
It
has a low level of electrical conductivity as well. This allows it to be highly
effective in electronic products.
Because
of these advantages, polypropylene is likely to be in most American homes. This
versatile plastic is one of the most commonly used in these situations.
