5 Logic behind why Acrylic Plastic Is utilized For Automotive Glazing

Polycarbonate had earned the tag because the best option material to be used within the automotive industry. However, in recent years, Polymethyl Methacrylate, the PMMA polymer or commonly known acrylic plastic, has efficiently risen towards the growing demands from the automotive industry in replacing polycarbonate for the best important used in a, namely, automotive glazing.


Long established to be used in a variety of vehicle applications such as decorative trim, ambient lighting and door entry strips, automotive glazing is just one of those fields that supply the greatest growth potential for PMMA.
Related key features of acrylic plastic which make it suitable for the operation of automotive glazing are discussed below.
Transportable
To produce a comparison with a erogenous level, PMMA is half the extra weight and more transparent than glass, thereby providing really clear visibility even just in the situation of fluctuating and unstable temperatures. Due to its molecular structure, thermoformed pmma thermoplastic are now used almost only for car window glazing where all of the necessary requirements for light-weight materials which might be safe, simple to process and perform in all of the weathers are met.
On 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 get fulfilled to fulfill the best state of scratch resistance. The use of a coating thus remains mandatory. Since PMMA is intrinsically UV and also weathering-resistant, a single-step coating is successful. As opposed, thermoplastics that have low capacity weathering demand a two-step coating system. This brings about relatively high costs for coating.
New design possibilities
PMMA glazing is Forty to fifty percent lighter than conventional glass, which piques the eye of automobile manufacturers. Using the advantages being immediately obvious, PMMA is now considered the right fit for automotive glazing. Weight savings apart, the transparency of acrylic plastic in addition to its quite high weathering resistance, pleasant acoustic properties, and exceptional form ability allow freedom enabling entirely new design possibilities.
Less anxiety birefringence
PMMA exhibits little or no stress birefringence this also works as a major benefit over other thermoplastics such as polycarbonate, which has been primarily used by glazing in the past. Compared with traditional materials such as polycarbonate, moulded PMMA, supplies a distinct potential for functional integration – reducing recess depth and assembly costs.
Environment-friendly
The modern goal within the automotive industry is to build up clean low fuel consumption vehicles. Given the awareness and also the requirement of eco-friendly initiatives in the current scheme of things, PMMA works as a perfect alternative to glass within the automotive glazing segment. As vehicle manufacturers push the boundaries of design, also is automotive glazing evolving.
