Polymers have for lengthy been a fundamental portion of our everyday lives because of this that examples are available almost ubiquitously. We generally have the feeling top us to imagine that polymers are simply just plastics used for packaging, in household objects as well as for making fibres, however this is simply the tip from the iceberg.

Polymers are used in many applications you may not have thought much about. This website enlightens you regarding the story behind polymers and the way it’s evolved from the time to provide several functions across quite a few industries.
Origin of polymer science
Humans have benefit from the flexibility of polymers for centuries as oils, tars, resins and gums. However, it wasn’t until the industrial revolution the polymer industry developed. In fact, the birth of polymer science may be traced to the mid-nineteenth century. From the 1830s, Charles Goodyear developed the vulcanization procedure that transformed the sticky latex of natural rubber right into a useful elastomer for tire use. In 1909, Leo Hendrik Baekeland created a resin from two very common chemicals, phenol and formaldehyde. The response between these two chemicals paved the way to add mass to a resin, called Bakelite, named after him. It turned out this resin that served as being a harbinger to a lot of from the common polymers that people use today. The phrase “polymer” is derived from the Greek roots “poly” and “mer,” which assembled means “many parts.” Polymeric substances are made of countless chemical units called monomers, that are joined together into large molecular chains made up of a large number of atoms.
Classification of polymers
Based on their origin, pmma plastic may be classified as synthetic or natural polymers. Natural polymers are those polymers that happen in nature and that that are isolated from plant and animal resources. Starch, cellulose, proteins, natural rubber etc. are a few samples of natural polymers. Though these are processed to find the end product, because the basic material comes from a natural source, these polymers are known as natural polymers. Natural rubber received from tree latex is actually a polymer produced from isoprene units using a tiny proportion of impurities inside.
Within this context, biopolymers can also be significant. There exists vast number of biopolymers including polysaccharides, polyesters, and polyamides. They may be naturally created by microorganisms. The genetic manipulation of microorganisms makes opportinity for enormous potential for the biotechnological manufacture of biopolymers with tailored properties ideal for high-value medical application including tissue engineering and drug delivery.
Synthetic polymers, as their name indicates, are synthesized within the laboratory or factory through a number of chemical reactions from low molecular weight compounds. In the functional viewpoint they may be classified into four main categories: thermoplastics, thermosets, elastomers and synthetic fibres. Polymethyl methacrylate (PMMA) is certainly one such thermoplastic created by the polymerization from the monomer, methyl methacrylate (MMA). PMMA is frequently called acrylic plastic and lends its properties with a various consumer product applications. Being both a thermoplastic and transparent plastic, acrylic is used extensively within the automotive industry in trunk release handles, master cylinder, and dashboard lighting. Consumer products that possess a constituent component of acrylic plastic include aquariums, motorcycle helmet lenses, paint, furniture, picture framing, and umbrella clamps, amongst others.
A number of the other synthetic polymers that people used in us include Nylons, utilized in fabrics and textiles, Teflon, utilized in non-stick pans and Polyvinyl Chloride, utilized in pipes.

Polycarbonate had earned the tag because the best option material for usage inside the automotive industry. However, recently, Polymethyl Methacrylate, the PMMA polymer or commonly known acrylic plastic, has efficiently risen towards the growing demands of the automotive industry in replacing polycarbonate for important use in the market, namely, automotive glazing.

Long established for usage in a number of vehicle applications like decorative trim, ambient lighting and door entry strips, automotive glazing is one of those fields that provide the highest growth risk of PMMA.
Related key features of acrylic plastic which make it ideal for the whole process of automotive glazing are discussed below.
Lightweight
To make a comparison over a erogenous level, PMMA is half the extra weight and much more transparent than glass, thereby providing superior visibility during the situation of fluctuating and unstable temperatures. Due to its molecular structure, thermoformed methyl methacrylate resin are used almost mainly for car window glazing where all of the necessary requirements for light-weight materials which might be safe, easy to process and perform in all weathers are met.
On top of Scratch Resistance
Another critical desire for glazing is scratch resistance. Standard PMMA already gets the highest surface hardness of thermoplastics regardless if uncoated. However, for automotive glazing, you’ll find stringent conditions to be fulfilled to satisfy the best condition of scratch resistance. The effective use of a coating is thus mandatory. Due to the fact PMMA is intrinsically UV in addition to weathering-resistant, a single-step coating is useful. In comparison, thermoplastics who have low potential to deal with weathering have to have a two-step coating system. This brings about relatively high costs 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 all the advantages being immediately obvious, PMMA is now considered 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 negative feelings birefringence
PMMA exhibits very little stress birefringence this also serves as a major benefit over other thermoplastics like polycarbonate, which has been primarily employed for glazing during the past. In comparison with traditional materials like polycarbonate, moulded PMMA, supplies a distinct potential for functional integration – reducing recess depth and assembly costs.
Environment-friendly
The modern goal inside the automotive companies are to formulate clean low fuel consumption vehicles. In the awareness as well as the dependence on 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 boundaries of design, so too is automotive glazing evolving.
SUMIPEX® PMMA polymer offers characteristics that match the latest challenges inside the transportation sector. It’s a monumental challenge for car makers that want to adjust to recent environmental requirements and so are thinking about alternatives that reduce greenhouse gas and save fuel. It does not take perfect partner with this movement since it can make cars lighter.
Being a leading manufacturer of SUMIPEX® PMMA polymer, Sumitomo Chemical is happy to help you out to understand its properties and exactly how it suitable to automotive glazing.
