Polymers have for too long been a fundamental piece of our everyday lives because of this that examples is found almost ubiquitously. We generally have the feeling that leads us to trust that polymers are simply just plastics useful for packaging, in household objects and for making fibres, however this is just the tip from the iceberg.

Polymers are utilized in many applications you will possibly not have thought much about. This web site enlightens you concerning the story behind polymers and the way it has evolved since that time to provide several functions across a host of industries.
Origin of polymer science
Humans have got advantage of the flexibility of polymers for hundreds of years available as oils, tars, resins and gums. However, it wasn’t before industrial revolution that this polymer industry started to realize. In reality, the birth of polymer science might be traced time for the mid-nineteenth century. In the 1830s, Charles Goodyear developed the vulcanization process that transformed the sticky latex of natural rubber in a useful elastomer for tire use. In 1909, Leo Hendrik Baekeland developed a resin from two quite typical chemicals, phenol and formaldehyde. The response between these chemicals led the way for the development of a resin, called Bakelite, named after him. It absolutely was this resin that served as being a harbinger to many from the common polymers that people use today. The phrase “polymer” is derived from the Greek roots “poly” and “mer,” which build means “many parts.” Polymeric substances are made of countless chemical units called monomers, that are gathered into large molecular chains consisting of 1000s of atoms.
Classification of polymers
On such basis as their origin, acrylic glass can be viewed as natural or synthetic polymers. Natural polymers are the ones polymers that appear in nature and that that are isolated from plant and animal resources. Starch, cellulose, proteins, natural rubber etc. are some samples of natural polymers. Though they may be processed to find the end result, considering that the basic material comes from a natural source, these polymers are called as natural polymers. Natural rubber originating from tree latex is essentially a polymer made out of isoprene units which has a tiny proportion of impurities in it.
On this context, biopolymers are also significant. There’s huge variety of biopolymers like polysaccharides, polyesters, and polyamides. They are naturally produced by microorganisms. The genetic manipulation of microorganisms makes way for enormous prospect of the biotechnological output of biopolymers with tailored properties ideal for high-value medical application like tissue engineering and drug delivery.
Synthetic polymers, his or her name indicates, are synthesized within the laboratory or factory by having a group of chemical reactions from low molecular weight compounds. From the functional viewpoint they may be classified into four main categories: thermoplastics, thermosets, elastomers and artificial fibres. Polymethyl methacrylate (PMMA) is but one such thermoplastic produced by the polymerization from the monomer, methyl methacrylate (MMA). PMMA is commonly referred to as acrylic plastic and lends its properties into a various consumer product applications. Being both a thermoplastic and transparent plastic, acrylic is employed extensively within the automotive industry in trunk release handles, master cylinder, and dashboard lighting. Consumer products that use a constituent element of acrylic plastic include aquariums, motorcycle helmet lenses, paint, furniture, picture framing, and umbrella clamps, among others.
A number of the other synthetic polymers that people use in us include Nylons, employed in fabrics and textiles, Teflon, employed in non-stick pans and Polyvinyl Chloride, employed in pipes.

Polycarbonate had earned the tag since the the best option material to be used from the automotive industry. However, in recent years, Polymethyl Methacrylate, the PMMA polymer or commonly known acrylic plastic, has efficiently risen to the growing demands in the automotive industry in replacing polycarbonate for the most important used in the market, namely, automotive glazing.

Long established to be used in several vehicle applications including decorative trim, ambient lighting and door entry strips, automotive glazing is among those fields that supply the very best growth risk of PMMA.
Related key features of acrylic plastic which make it suitable for the entire process of automotive glazing are discussed below.
Transportable
To make a comparison on the standard level, PMMA is half the weight plus more transparent than glass, thereby providing magnificent visibility even in the truth of fluctuating and unstable temperatures. As a result of its molecular structure, thermoformed polymethyl methacrylate are used almost only for car window glazing where all of the necessary requirements for light-weight materials which might be safe, simple to process and perform in all of the weathers are met.
On top of Scratch Resistance
Another essential requirement of glazing is scratch resistance. Standard PMMA already has got the highest surface hardness of most thermoplastics even though uncoated. However, for automotive glazing, you will find stringent conditions to become fulfilled to meet the optimal state of scratch resistance. The effective use of a coating is therefore mandatory. Since PMMA is intrinsically UV and also weathering-resistant, a single-step coating is effective. On the other hand, thermoplastics who have low resistance to weathering need a two-step coating system. This brings about relatively expense for coating.
New design possibilities
PMMA glazing is Forty to fifty percent lighter than conventional glass, which piques a persons vision of automobile manufacturers. With the advantages being immediately obvious, PMMA is now viewed as the best fit for automotive glazing. Weight savings apart, the transparency of acrylic plastic in addition to its quite high weathering resistance, pleasant acoustic properties, and exceptional form ability allow freedom enabling entirely new design possibilities.
Less anxiety birefringence
PMMA exhibits very little stress birefringence which serves as a major benefit over other thermoplastics including polycarbonate, which has been primarily used by glazing in the past. In contrast to traditional materials including polycarbonate, moulded PMMA, provides a distinct potential for functional integration – reducing recess depth and assembly costs.
Environment-friendly
The new goal from the automotive companies are to build up clean low fuel consumption vehicles. Given the awareness along with the need for eco-friendly initiatives in today’s general scheme of things, PMMA serves as a perfect substitute for glass from the automotive glazing segment. As vehicle manufacturers push the bounds of design, so too is automotive glazing evolving.
SUMIPEX® PMMA polymer offers characteristics that fulfill the latest challenges from the transportation sector. It’s a monumental challenge for auto makers that want to adjust to recent environmental requirements and therefore are contemplating alternatives that reduce greenhouse gas and save fuel. It’s the perfect partner within this movement since it tends to make cars lighter.
As being a leading manufacturer of SUMIPEX® PMMA polymer, Sumitomo Chemical is pleased to work with you in understanding its properties and how it best suited to automotive glazing.
