5 Main reasons why Acrylic Plastic Is employed For Automotive Glazing

Polycarbonate had earned the tag since the the most appropriate material for usage inside the automotive industry. However, in recent years, Polymethyl Methacrylate, the PMMA polymer or commonly known acrylic plastic, has efficiently risen on the growing demands from the automotive industry in replacing polycarbonate for important use within a, namely, automotive glazing.


Long established for usage in a variety of vehicle applications such as decorative trim, ambient lighting and door entry strips, automotive glazing is one kind of those fields that offer the greatest growth potential for PMMA.
Related key features of acrylic plastic which make it perfect for the entire process of automotive glazing are discussed below.
Light-weight
To create a comparison with a erogenous level, PMMA is half the weight plus much more transparent than glass, thereby providing magnificent visibility during the case of fluctuating and unstable temperatures. As a result of its molecular structure, thermoformed methyl methacrylate resin are actually 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 every weathers are met.
At the top of Scratch Resistance
Another critical requirement of glazing is scratch resistance. Standard PMMA already gets the highest surface hardness of all thermoplastics even though uncoated. However, for automotive glazing, you can find stringent conditions to be fulfilled to meet the best state of scratch resistance. The application of a coating thus remains mandatory. Given that PMMA is intrinsically UV and also weathering-resistant, a single-step coating is useful. As opposed, thermoplastics who have low resistance to weathering demand a two-step coating system. This leads to 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 the advantages being immediately obvious, PMMA is considered the right fit for automotive glazing. Weight savings apart, the transparency of acrylic plastic in addition to 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 almost no stress birefringence and this works as a major benefit over other thermoplastics such as polycarbonate, which was primarily used for glazing in the past. Compared with traditional materials such as polycarbonate, moulded PMMA, provides a distinct possibility of functional integration – reducing recess depth and assembly costs.
Environment-friendly
The brand new goal inside the automotive companies are to produce clean low fuel consumption vehicles. Given the awareness and also the need for eco-friendly initiatives in the present general scheme of things, PMMA works as a perfect alternative 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 that are looking to adjust to recent environmental requirements and therefore are thinking about alternatives that reduce greenhouse gas and save fuel. It’s the perfect partner on this movement because it can make cars lighter.
