5 Logic behind why Acrylic Plastic Is utilized For Automotive Glazing

Posted on by

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


Long established for use in several vehicle applications like decorative trim, ambient lighting and door entry strips, automotive glazing is one of those fields that supply the very best growth possibility of PMMA.
Related key options that come with acrylic plastic which make it suitable for the process of automotive glazing are discussed below.
Transportable
To generate a comparison on a simple level, PMMA is half the weight and more transparent than glass, thereby providing really clear visibility during the truth of fluctuating and unstable temperatures. As a result of its molecular structure, thermoformed thermoplastic resin are now used almost just for car window glazing where every one of the necessary requirements for light-weight materials which can be safe, very easy to process and perform in every weathers are met.
At the top of Scratch Resistance
Another critical requirement of glazing is scratch resistance. Standard PMMA already contains the highest surface hardness of most thermoplastics even if uncoated. However, for automotive glazing, you will find stringent conditions to get fulfilled to fulfill the ideal condition of scratch resistance. The usage of a coating is therefore mandatory. Given that PMMA is intrinsically UV and also weathering-resistant, a single-step coating is effective. As opposed, thermoplastics which may have low effectiveness against weathering require a two-step coating system. This results in relatively expensive for coating.
New design possibilities
PMMA glazing is Forty to fifty percent lighter than conventional glass, which piques the eye of automobile manufacturers. Using the advantages being immediately obvious, PMMA is considered the proper 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 stress birefringence
PMMA exhibits hardly any stress birefringence and also this functions as a major benefit over other thermoplastics like polycarbonate, that was primarily used for glazing before. Compared with traditional materials like 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 produce clean low fuel consumption vehicles. Due to the awareness along with the dependence on eco-friendly initiatives with the current economic scheme of things, PMMA functions 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 looking to sit in recent environmental requirements and so are thinking of alternatives that reduce greenhouse gas and save fuel. It is the perfect partner within this movement given it makes cars lighter.
As being a leading manufacturer of SUMIPEX® PMMA polymer, Sumitomo Chemical is happy to help you out understand its properties and just how it ideal to automotive glazing.
