5 Logic behind why Acrylic Plastic Is utilized For Automotive Glazing

Posted on by

Polycarbonate had earned the tag because the best option material for usage from the automotive industry. However, in recent years, Polymethyl Methacrylate, the PMMA polymer or commonly known acrylic plastic, has efficiently risen on the growing demands of the automotive industry in replacing polycarbonate for the most important utilization in the industry, namely, automotive glazing.


Long established for usage in several vehicle applications for example decorative trim, ambient lighting and door entry strips, automotive glazing is among those fields that provide 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.
Lightweight
To produce a comparison on a very basic level, PMMA is half the body weight and much more transparent than glass, thereby providing really clear visibility even during the situation of fluctuating and unstable temperatures. Due to its molecular structure, thermoformed pmma plastic are actually used almost mainly for car window glazing where all the necessary requirements for light-weight materials which can be safe, easy to process and perform in all weathers are met.
On top of Scratch Resistance
Another important desire for glazing is scratch resistance. Standard PMMA already gets the highest surface hardness coming from all thermoplastics even though uncoated. However, for automotive glazing, you’ll find stringent conditions to get fulfilled in order to meet the perfect condition of scratch resistance. The application of a coating is thus mandatory. Considering that PMMA is intrinsically UV as well as weathering-resistant, a single-step coating is useful. On the other hand, thermoplastics which may have low effectiveness against weathering demand a two-step coating system. This ends in relatively expense 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 currently considered the proper 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 stress birefringence
PMMA exhibits little or no stress birefringence this also operates as a major benefit over other thermoplastics for example polycarbonate, that has been primarily employed for glazing before. In comparison with traditional materials for example polycarbonate, moulded PMMA, supplies a distinct chance of functional integration – reducing recess depth and assembly costs.
Environment-friendly
The brand new goal from the automotive companies are to build up clean low fuel consumption vehicles. Given the awareness along with the requirement for eco-friendly initiatives with the current economic scheme of things, PMMA operates as a perfect alternative to glass from the automotive glazing segment. As vehicle manufacturers push the bounds of design, also is automotive glazing evolving.
SUMIPEX® PMMA polymer offers characteristics that meet the latest challenges from the transportation sector. It’s a monumental challenge for auto makers that are looking to adjust to recent environmental requirements and therefore are contemplating alternatives that reduce greenhouse gas and save fuel. Oahu is the perfect partner within this movement since it makes cars lighter.
