Polycarbonate had earned the tag since the the most suitable material to be used inside the automotive industry. However, these days, Polymethyl Methacrylate, the PMMA polymer or commonly known acrylic plastic, has efficiently risen towards the growing demands of the automotive industry in replacing polycarbonate for important used in the, namely, automotive glazing.
Long established to be used in several vehicle applications like decorative trim, ambient lighting and door entry strips, automotive glazing is among those fields offering the very best growth risk of PMMA.
Related key popular features of acrylic plastic which make it perfect for the whole process of automotive glazing are discussed below.
Transportable
To generate a comparison with a very basic level, PMMA is half the body weight plus more transparent than glass, thereby providing superior visibility even during the case of fluctuating and unstable temperatures. Due to its molecular structure, thermoformed thermoplastic resin are used almost exclusively for car window glazing where every one of the necessary requirements for light-weight materials which might be safe, simple to process and perform in most weathers are met.
On top of Scratch Resistance
Another essential requirement of glazing is scratch resistance. Standard PMMA already contains the highest surface hardness of most thermoplastics even if uncoated. However, for automotive glazing, you can find stringent conditions to become fulfilled to satisfy the ideal state of scratch resistance. The use of a coating is thus mandatory. Considering that PMMA is intrinsically UV and also weathering-resistant, a single-step coating is successful. As opposed, thermoplastics which have low capacity 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 a persons vision of automobile manufacturers. Using the advantages being immediately obvious, PMMA is currently known as the best 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 stress birefringence
PMMA exhibits little or no stress birefringence which works as a major benefit over other thermoplastics like polycarbonate, which has been primarily useful for glazing in the past. Compared with traditional materials like polycarbonate, moulded PMMA, provides a distinct chance of functional integration – reducing recess depth and assembly costs.
Environment-friendly
The brand new goal inside the automotive industry is to develop clean low fuel consumption vehicles. Because of the awareness and also the requirement of eco-friendly initiatives with the current economic scheme of things, PMMA works as a perfect substitute for glass inside the automotive glazing segment. As vehicle manufacturers push the boundaries of design, so too is automotive glazing evolving.
