Polycarbonate had earned the tag because the most suitable material to be used from the automotive industry. However, recently, Polymethyl Methacrylate, the PMMA polymer or commonly known acrylic plastic, has efficiently risen on the growing demands with the automotive industry in replacing polycarbonate which are more important used in the, namely, automotive glazing.
Long established to be used in many different vehicle applications for example decorative trim, ambient lighting and door entry strips, automotive glazing is one kind of those fields that supply the very best growth possibility of PMMA.
Related key popular features of acrylic plastic that make it perfect for the whole process of automotive glazing are discussed below.
Light-weight
To generate a comparison on the standard level, PMMA is half the load and more transparent than glass, thereby providing magnificent visibility even just in true of fluctuating and unstable temperatures. Owing to its molecular structure, thermoformed acrylic sheet are used almost just for car window glazing where all of the necessary requirements for light-weight materials that are safe, simple to process and perform in all of the weathers are met.
High on Scratch Resistance
Another significant requirement of glazing is scratch resistance. Standard PMMA already contains the highest surface hardness of all thermoplastics even though uncoated. However, for automotive glazing, you can find stringent conditions to get fulfilled to meet the best state of scratch resistance. The use of a coating is thus mandatory. Due to the fact PMMA is intrinsically UV and also weathering-resistant, a single-step coating is effective. On the other hand, thermoplastics that have low resistance to weathering demand 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 interest of automobile manufacturers. Together with the advantages being immediately obvious, PMMA has become viewed as the correct fit for automotive glazing. Weight savings apart, the transparency of acrylic plastic with its quite high weathering resistance, pleasant acoustic properties, and exceptional form ability allow freedom enabling entirely new design possibilities.
Less anxiety birefringence
PMMA exhibits almost no stress birefringence and this operates as a major benefit over other thermoplastics for example polycarbonate, which was primarily employed for glazing previously. Weighed against traditional materials for example polycarbonate, moulded PMMA, supplies a distinct potential for functional integration – reducing recess depth and assembly costs.
Environment-friendly
The newest goal from the automotive market is to formulate clean low fuel consumption vehicles. Because of the awareness and also the dependence on eco-friendly initiatives in the current general scheme of things, PMMA operates as a perfect replacement for glass from the automotive glazing segment. As vehicle manufacturers push the boundaries of design, also is automotive glazing evolving.
SUMIPEX® PMMA polymer offers characteristics that meet the latest challenges from the transportation sector. It’s a monumental challenge for car makers that are looking for to sit in recent environmental requirements and therefore are thinking of alternatives that reduce greenhouse gas and save fuel. It is the perfect partner in this movement given it helps make cars lighter.
As being a leading manufacturer of SUMIPEX® PMMA polymer, Sumitomo Chemical is satisfied to work with you in understanding its properties and just how it best suited to automotive glazing.
