5 Logic behind why Acrylic Plastic Is utilized For Automotive Glazing

Polycarbonate had earned the tag because the best option material for use from the automotive industry. However, in recent times, Polymethyl Methacrylate, the PMMA polymer or commonly known acrylic plastic, has efficiently risen to the growing demands of the automotive industry in replacing polycarbonate which are more important used in the market, namely, automotive glazing.

Long established for use in a number of vehicle applications like decorative trim, ambient lighting and door entry strips, automotive glazing is just one of those fields that provide the very best growth potential for PMMA.
Related key features of acrylic plastic which make it suitable for the entire process of automotive glazing are discussed below.
Lightweight
To create a comparison on a simple level, PMMA is half the weight and much more transparent than glass, thereby providing crystal clear visibility even during the situation of fluctuating and unstable temperatures. Due to its molecular structure, thermoformed acrylic sheet are now used almost just for car window glazing where every one of the necessary requirements for light-weight materials which might be safe, 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 coming from all thermoplastics even when uncoated. However, for automotive glazing, you will find stringent conditions to get fulfilled to fulfill the best state of scratch resistance. The application of a coating is thus mandatory. Considering that PMMA is intrinsically UV and also weathering-resistant, a single-step coating is successful. In comparison, thermoplastics which have low resistance to weathering need 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. With the advantages being immediately obvious, PMMA has become considered the proper fit for automotive glazing. Weight savings apart, the transparency of acrylic plastic with its very high weathering resistance, pleasant acoustic properties, and exceptional form ability allow freedom enabling entirely new design possibilities.
Less negative feelings birefringence
PMMA exhibits little or no stress birefringence this also functions as a major benefit over other thermoplastics like polycarbonate, which was primarily used for glazing during the past. In contrast to traditional materials like polycarbonate, moulded PMMA, supplies a distinct chance for functional integration – reducing recess depth and assembly costs.
Environment-friendly
The brand new goal from the automotive industry is to produce clean low fuel consumption vehicles. Due to the awareness along with the need for eco-friendly initiatives in today’s general scheme of things, PMMA functions as a perfect replacement for glass from the automotive glazing segment. As vehicle manufacturers push the boundaries of design, so too is automotive glazing evolving.
SUMIPEX® PMMA polymer offers characteristics that satisfy the latest challenges from the transportation sector. It’s a monumental challenge for auto makers that are looking for 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 on this movement as it helps make cars lighter.
