Polymers have for long been an integral part of our everyday lives so much in fact that examples is found almost ubiquitously. We have an impact that leads us to think that polymers are only plastics utilized for packaging, in household objects as well as for making fibres, however, this is just the tip with the iceberg.

Polymers are employed in many applications you may not have thought much about. This website enlightens you concerning the story behind polymers and exactly how they have evolved since that time to serve several functions across a host of industries.
Origin of polymer science
Humans have benefit from the flexibility of polymers for hundreds of years available as oils, tars, resins and gums. However, it wasn’t before the industrial revolution the polymer industry began to develop. In fact, the birth of polymer science may be traced returning to the mid-nineteenth century. Within the 1830s, Charles Goodyear developed the vulcanization process that transformed the sticky latex of natural rubber in to a useful elastomer for tire use. In 1909, Leo Hendrik Baekeland developed a resin from two quite normal chemicals, phenol and formaldehyde. The reaction between these chemicals paved the way to add mass to a resin, called Bakelite, named after him. It turned out this resin that served being a harbinger to many people with the common polymers that individuals use today. The word “polymer” hails from the Greek roots “poly” and “mer,” which come up with means “many parts.” Polymeric substances are composed of many chemical units called monomers, that are joined together into large molecular chains composed of 1000s of atoms.
Classification of polymers
Based on their origin, sumitomo chemical asia might be classified as natural or synthetic polymers. Natural polymers are those polymers that exist in nature knowning that that are isolated from plant and animal resources. Starch, cellulose, proteins, natural rubber etc. are several examples of natural polymers. Though these are processed to get the result, since basic material comes from a natural source, these polymers are called as natural polymers. Natural rubber received from tree latex is essentially a polymer made from isoprene units using a small percentage of impurities inside it.
With this context, biopolymers may also be significant. There is certainly vast number of biopolymers such as polysaccharides, polyesters, and polyamides. They are naturally manufactured by microorganisms. The genetic manipulation of microorganisms makes opportinity for enormous risk of the biotechnological manufacture of biopolymers with tailored properties well suited for high-value medical application such as tissue engineering and drug delivery.
Synthetic polymers, as his or her name indicates, are synthesized within the laboratory or factory by having a series of chemical reactions from low molecular weight compounds. From the functional perspective they are often classified into four main categories: thermoplastics, thermosets, elastomers and synthetic fibres. Polymethyl methacrylate (PMMA) is certainly one such thermoplastic manufactured by the polymerization with the monomer, methyl methacrylate (MMA). PMMA is often generally known as acrylic plastic and lends its properties into a various consumer product applications. Being both a thermoplastic and transparent plastic, acrylic can be used extensively within the automotive industry in trunk release handles, master cylinder, and dashboard lighting. Consumer items that have a very constituent component of acrylic plastic include aquariums, motorcycle helmet lenses, paint, furniture, picture framing, and umbrella clamps, and others.
Some of the other synthetic polymers that individuals use within our everyday life include Nylons, utilized in fabrics and textiles, Teflon, utilized in non-stick pans and Polyvinyl Chloride, utilized in pipes.

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

Long established to be used in a number of vehicle applications for example decorative trim, ambient lighting and door entry strips, automotive glazing is one kind of those fields that provide the highest growth possibility of PMMA.
Related key features of acrylic plastic which make it perfect for the operation of automotive glazing are discussed below.
Lightweight
To produce a comparison on a standard level, PMMA is half the body weight plus more transparent than glass, thereby providing really clear visibility even during true of fluctuating and unstable temperatures. Due to its molecular structure, thermoformed acrylic sheet are now used almost just for car window glazing where all of the necessary requirements for light-weight materials that are safe, an easy task to process and perform in all of the weathers are met.
At the top of Scratch Resistance
Another essential desire for glazing is scratch resistance. Standard PMMA already gets the highest surface hardness of thermoplastics even when uncoated. However, for automotive glazing, you will find stringent conditions being fulfilled to satisfy the perfect state of scratch resistance. The usage of a coating thus remains mandatory. Due to the fact PMMA is intrinsically UV in addition to weathering-resistant, a single-step coating works well. On the other hand, thermoplastics which have low resistance to weathering need a two-step coating system. This leads to 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 has become viewed as the proper fit for automotive glazing. Weight savings apart, the transparency of acrylic plastic as well as its quite high weathering resistance, pleasant acoustic properties, and exceptional form ability allow freedom enabling entirely new design possibilities.
Less stress birefringence
PMMA exhibits very little stress birefringence this also serves as a major benefit over other thermoplastics for example polycarbonate, which was primarily useful for glazing during the past. Weighed against traditional materials for example polycarbonate, moulded PMMA, offers a distinct chance for functional integration – reducing recess depth and assembly costs.
Environment-friendly
The new goal inside the automotive industry is to develop clean low fuel consumption vehicles. Because of the awareness along with the requirement of eco-friendly initiatives in the current general scheme of things, PMMA serves as a perfect option to glass inside the automotive glazing segment. As vehicle manufacturers push the bounds of design, also is automotive glazing evolving.
SUMIPEX® PMMA polymer offers characteristics that match the latest challenges inside the transportation sector. It’s a monumental challenge for auto makers that are looking to sit in recent environmental requirements and are considering alternatives that reduce greenhouse gas and save fuel. It is the perfect partner on this movement because it can make cars lighter.
