Polycarbonate had earned the tag as the the best option material to be used in 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 which are more important use within the, namely, automotive glazing.
Long established to be used in a number of vehicle applications such as decorative trim, ambient lighting and door entry strips, automotive glazing is among those fields that offer the greatest growth potential for PMMA.
Related key popular features of acrylic plastic making it perfect for the process of automotive glazing are discussed below.
Lightweight
To produce a comparison on a standard level, PMMA is half the load and more transparent than glass, thereby providing crystal clear visibility even in the truth of fluctuating and unstable temperatures. Because of its molecular structure, thermoformed thermoplastic resin have become used almost just for car window glazing where every one of the necessary requirements for light-weight materials that are safe, easy to process and perform in most weathers are met.
High on Scratch Resistance
Another critical desire for glazing is scratch resistance. Standard PMMA already gets the highest surface hardness of all thermoplastics regardless if uncoated. However, for automotive glazing, you will find stringent conditions to get fulfilled to fulfill the perfect state of scratch resistance. The effective use of a coating is therefore mandatory. Given that PMMA is intrinsically UV in addition to 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 eye of automobile manufacturers. With all the advantages being immediately obvious, PMMA is known as the correct fit for automotive glazing. Weight savings apart, the transparency of acrylic plastic along with its very 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 works as a major benefit over other thermoplastics such as polycarbonate, which was primarily used for glazing previously. Weighed against traditional materials such as polycarbonate, moulded PMMA, provides a distinct chance of functional integration – reducing recess depth and assembly costs.
Environment-friendly
The new goal in the automotive marketplace is to produce clean low fuel consumption vehicles. Due to the awareness and the requirement of eco-friendly initiatives in the current general scheme of things, PMMA works as a perfect alternative to glass in the automotive glazing segment. As vehicle manufacturers push the boundaries of design, also is automotive glazing evolving.
