5 Logic behind why Acrylic Plastic Is utilized For Automotive Glazing

Polycarbonate had earned the tag since the the most appropriate material to be used inside the automotive industry. However, these days, 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 the best important use within the industry, namely, automotive glazing.

Long established to be used in many different vehicle applications for example decorative trim, ambient lighting and door entry strips, automotive glazing is one of those fields that supply the best growth risk of PMMA.
Related key features of acrylic plastic that make it well suited for the whole process of automotive glazing are discussed below.
Transportable
To generate a comparison on the standard level, PMMA is half the body weight and much more transparent than glass, thereby providing superior visibility during true of fluctuating and unstable temperatures. Owing to its molecular structure, thermoformed Acrylic Plastic are used almost mainly for car window glazing where all of the necessary requirements for light-weight materials which can be safe, an easy task to process and perform in every weathers are met.
On top of Scratch Resistance
Another significant requirement of glazing is scratch resistance. Standard PMMA already has the highest surface hardness of all thermoplastics regardless if uncoated. However, for automotive glazing, you can find stringent conditions to be fulfilled to meet the optimal state of scratch resistance. The application of a coating is thus mandatory. Considering that PMMA is intrinsically UV and also weathering-resistant, a single-step coating is useful. As opposed, thermoplastics that have low resistance to weathering need a two-step coating system. This results in relatively expense for coating.
New design possibilities
PMMA glazing is 40 to 50 percent lighter than conventional glass, which piques the interest of automobile manufacturers. With all the advantages being immediately obvious, PMMA is viewed as the correct fit for automotive glazing. Weight savings apart, the transparency of acrylic plastic along 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 almost no stress birefringence and this works as a major benefit over other thermoplastics for example polycarbonate, which was primarily used for glazing previously. Weighed against traditional materials for example polycarbonate, moulded PMMA, comes with a distinct potential for functional integration – reducing recess depth and assembly costs.
Environment-friendly
The newest goal inside the automotive marketplace is to build up clean low fuel consumption vehicles. Due to the awareness and also the requirement of eco-friendly initiatives in the present general scheme of things, PMMA works as a perfect replacement for glass inside the automotive glazing segment. As vehicle manufacturers push the boundaries of design, also is automotive glazing evolving.
