Search engine for touristic excursions to any place in the world Polycarbonate had earned the tag since the most suitable material for use in the automotive industry. However, these days, Polymethyl Methacrylate, the PMMA polymer or commonly known acrylic plastic, has efficiently risen on the growing demands with the automotive industry in replacing polycarbonate for the best important use within a, 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 offering the best growth possibility of PMMA.
Related key popular features of acrylic plastic which render it ideal for the process of automotive glazing are discussed below.
Light-weight
To produce a comparison on a very basic level, PMMA is half the body weight plus much more transparent than glass, thereby providing really clear visibility even just in the case of fluctuating and unstable temperatures. As a result of its molecular structure, thermoformed pmma plastic are now used almost exclusively for car window glazing where all the necessary requirements for light-weight materials that are safe, simple to process and perform in every weathers are met.
At the top of Scratch Resistance
Another essential dependence on glazing is scratch resistance. Standard PMMA already gets the highest surface hardness coming from all thermoplastics even if uncoated. However, for automotive glazing, you’ll find stringent conditions to become fulfilled in order to meet the optimal state of scratch resistance. The effective use of a coating is thus mandatory. Considering that PMMA is intrinsically UV along with weathering-resistant, a single-step coating is effective. In contrast, thermoplastics which have low effectiveness against weathering have to have a two-step coating system. This results in relatively high costs for coating.
New design possibilities
PMMA glazing is Forty to fifty percent lighter than conventional glass, which piques a person’s eye of automobile manufacturers. With the advantages being immediately obvious, PMMA is known as the right fit for automotive glazing. Weight savings apart, the transparency of acrylic plastic with its quite high weathering resistance, pleasant acoustic properties, and exceptional form ability allow freedom enabling entirely new design possibilities.
Less anxiety birefringence
PMMA exhibits hardly any stress birefringence this also serves as a major benefit over other thermoplastics like polycarbonate, that was primarily used by glazing before. Weighed against traditional materials like polycarbonate, moulded PMMA, supplies a distinct potential for functional integration – reducing recess depth and assembly costs.
Environment-friendly
The new goal in the automotive market is to develop clean low fuel consumption vehicles. In the awareness along with the requirement for eco-friendly initiatives in the current scheme of things, PMMA serves as a perfect option to glass in the automotive glazing segment. As vehicle manufacturers push the bounds of design, also is automotive glazing evolving.
