5 Explanations why Acrylic Plastic Is Used For Automotive Glazing
Polycarbonate had earned the tag because the most suitable material to use from the automotive industry. However, in recent years, Polymethyl Methacrylate, the PMMA polymer or commonly known acrylic plastic, has efficiently risen on the growing demands in the automotive industry in replacing polycarbonate for the best important utilization in a, namely, automotive glazing.
Long established to use in several vehicle applications for example decorative trim, ambient lighting and door entry strips, automotive glazing is among those fields that supply the best growth potential for PMMA.
Related key popular features of acrylic plastic which make it well suited for the entire process of automotive glazing are discussed below.
Lightweight
To create a comparison over a erogenous level, PMMA is half the extra weight and more transparent than glass, thereby providing really clear visibility even in true of fluctuating and unstable temperatures. Owing to its molecular structure, thermoformed sumitomo chemical asia are used almost just for car window glazing where each of the necessary requirements for light-weight materials which are safe, simple to process and perform in every weathers are met.
On top of Scratch Resistance
Another important requirement for glazing is scratch resistance. Standard PMMA already gets the highest surface hardness of all thermoplastics even when uncoated. However, for automotive glazing, there are stringent conditions to get fulfilled in order to meet the perfect state of scratch resistance. The application of a coating is therefore mandatory. Since PMMA is intrinsically UV and also weathering-resistant, a single-step coating is effective. As opposed, thermoplastics who have low resistance to weathering have to have a two-step coating system. This brings about relatively expensive for coating.
New design possibilities
PMMA glazing is 40 to 50 percent lighter than conventional glass, which piques a persons vision of automobile manufacturers. With the advantages being immediately obvious, PMMA has become seen as the proper fit for automotive glazing. Weight savings apart, the transparency of acrylic plastic along with its extremely 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 and also this works as a major benefit over other thermoplastics for example polycarbonate, that has been primarily employed for glazing previously. Weighed against traditional materials for example polycarbonate, moulded PMMA, provides a distinct chance of functional integration – reducing recess depth and assembly costs.
Environment-friendly
The newest goal from the automotive industry is to build up clean low fuel consumption vehicles. Given the awareness along with the dependence on eco-friendly initiatives in the current general scheme of things, PMMA works as a perfect option to glass from the automotive glazing segment. As vehicle manufacturers push the boundaries of design, also is automotive glazing evolving.
