5 Logic behind why Acrylic Plastic Is employed For Automotive Glazing

Polycarbonate had earned the tag because the most appropriate material to use within the automotive industry. However, these days, Polymethyl Methacrylate, the PMMA polymer or commonly known acrylic plastic, has efficiently risen towards the growing demands from the automotive industry in replacing polycarbonate which are more important use within the industry, namely, automotive glazing.

Long established to use in many different vehicle applications including decorative trim, ambient lighting and door entry strips, automotive glazing is one kind of those fields that offer the best growth risk of PMMA.
Related key features of acrylic plastic making it well suited for the operation of automotive glazing are discussed below.
Light-weight
To produce a comparison with a standard level, PMMA is half the body weight plus much more transparent than glass, thereby providing crystal clear visibility during the case of fluctuating and unstable temperatures. As a result of its molecular structure, thermoformed acrylic glass have become used almost only for car window glazing where each of the necessary requirements for light-weight materials which can be safe, very easy to process and perform in all weathers are met.
At the top of Scratch Resistance
Another important desire for glazing is scratch resistance. Standard PMMA already gets the highest surface hardness of all thermoplastics even if uncoated. However, for automotive glazing, there are stringent conditions to be fulfilled to satisfy the perfect state of scratch resistance. The application of a coating thus remains mandatory. Given that PMMA is intrinsically UV and also weathering-resistant, a single-step coating is effective. In contrast, thermoplastics that have low effectiveness against weathering require 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 a persons vision of automobile manufacturers. With the advantages being immediately obvious, PMMA is now considered the right fit for automotive glazing. Weight savings apart, the transparency of acrylic plastic as well as its extremely 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 this also operates as a major benefit over other thermoplastics including polycarbonate, which has been primarily employed for glazing during the past. Compared with traditional materials including polycarbonate, moulded PMMA, provides a distinct potential for functional integration – reducing recess depth and assembly costs.
Environment-friendly
The brand new goal within the automotive marketplace is to produce clean low fuel consumption vehicles. Due to the awareness and also the need for eco-friendly initiatives in today’s scheme of things, PMMA operates as a perfect option to glass within the automotive glazing segment. As vehicle manufacturers push the boundaries of design, also is automotive glazing evolving.
SUMIPEX® PMMA polymer offers characteristics that fulfill the latest challenges within the transportation sector. It’s a monumental challenge for auto makers that are looking for to adjust to recent environmental requirements and are thinking of alternatives that reduce greenhouse gas and save fuel. It is the perfect partner within this movement because it makes cars lighter.
