This article describes about Lexan polycarbonate sheet as a wonder material which can be used in different fields to facilitate all needs. The remarkable strength, excellent physical, thermal properties make it a perfect choice for a variety of applications. The industries which make use of this sheet and its advantages are also mentioned in the passages.
Engineers,
Scientists and architects are always on a quest for creating a new wonder
Material that can act as a replacement to existing ones, in the construction
Sector. Alternates are only considered when they prove their selves worthier
than their predecessors. The need for this exploration is because of the
Changing demands and conditions poised.
What is Lexan Polycarbonate?
The scientists who first discovered this
material did not know what they had created either! It was only after they let
the process complete Dr.Hermann Schnell and Dr.Daniel Fox who were
Independently working, realized that they had actually developed a hard,
Unbreakable, transparent substance. Polycarbonate resins are a type of plastics
Which could be achieved by the reaction of two chemical compounds; bisphenol A
and phosgene. When these components first reacted, they resulted in the
Formation of sticky glue like product. Upon condensing, this material show
Cased enormous strength had yet been subtle in weight. Lexan is a type or grade of
this thermo plastic.
So where is it used?
There are a
Variety of applications for this material and hence a mosaic of industries
makes use of it. The early applications included glazing and doming. Asbestos
served as an extraordinary alternative to roofs made of cement, palm leaves
etc. The changing scenarios and weather conditions forced civil engineers to
Use to opt for a better material as a replacement, which is when Lexan Polycarbonate sheets came into the picture. The relatively low weight and high load
bearing ability makes it an appropriate choice. Compared to asbestos, these
have better thermal and mechanical properties as well. This means on a hot
sunny day, a roof with the former will heat up and create convection more when
compared to the latter. For those architects who care equally about aesthetics
too, the excellent transparency this sheet offers comes as an additional gift. The
usage of this product is limited only by imagination. It is used to create
sports helmets, visors for head gear of astronauts, tail lights in automobile,
industrial safety boundary glasses etc. The icing on the cake was found in 1968
when it was found that by forming 1.25 inch thickness of this innovative sheet;
bullet proof glasses could be formed. Needless to say, bullet proof cars and
buses are of prime importance nowadays in securing the life of people. When eye
glasses were too heavy for people they were swapped with this amazing plastic
sheet. The resulting eye wear was precise and light weight. Conference halls,
meeting rooms and recording theaters always need to maintain an acoustically
comforting ambience to preserve the sound emanating from within. For this
purpose sound walls are made using multiple layers of Lexan.
Why is it preferred?
The main
reason why it is opted is because of its extremely high toughness. Not many
materials offer resistance to mechanical forces and vibrations as good as this.
Another startling advantage is its low weight. This means manufacturing,
transporting and installing would all be simple. The transparency takes care in
maintaining the required lighting and ambience.
Polycarbonate sheets no doubt bring in normal light from the sun but, they also reflect back the UV rays because they come with an additional defensive film layer.
