Polycarbonate had earned the tag because the the most appropriate material for usage inside the automotive industry. However, in recent times, 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 for usage in a variety of vehicle applications such as decorative trim, ambient lighting and door entry strips, automotive glazing is one of those fields that offer the highest growth possibility of PMMA.
Related key options that come with acrylic plastic that make it suitable for the operation of automotive glazing are discussed below.
Light weight
To create a comparison over a erogenous level, PMMA is half the load and much more transparent than glass, thereby providing magnificent visibility during true of fluctuating and unstable temperatures. Owing to its molecular structure, thermoformed acrylic glass are actually used almost exclusively for car window glazing where all of the necessary requirements for light-weight materials which are safe, an easy task to process and perform in most weathers are met.
High on Scratch Resistance
Another essential dependence on glazing is scratch resistance. Standard PMMA already has got the highest surface hardness of thermoplastics even if uncoated. However, for automotive glazing, you will find stringent conditions being fulfilled to fulfill the ideal state of scratch resistance. The usage of a coating thus remains mandatory. Due to the fact PMMA is intrinsically UV in addition to weathering-resistant, a single-step coating is effective. In comparison, thermoplastics who have low resistance to weathering demand a two-step coating system. This ends in relatively high costs for coating.
New design possibilities
PMMA glazing is 40 to 50 percent lighter than conventional glass, which piques the interest of automobile manufacturers. Together with the advantages being immediately obvious, PMMA is currently seen as the proper fit for automotive glazing. Weight savings apart, the transparency of acrylic plastic with its very high weathering resistance, pleasant acoustic properties, and exceptional form ability allow freedom enabling entirely new design possibilities.
Less negative feelings birefringence
PMMA exhibits almost no stress birefringence and also this operates as a major benefit over other thermoplastics such as polycarbonate, which has been primarily used by glazing previously. In comparison with traditional materials such as polycarbonate, moulded PMMA, comes with a distinct possibility of functional integration – reducing recess depth and assembly costs.
Environment-friendly
The brand new goal inside the automotive marketplace is to formulate clean low fuel consumption vehicles. In the awareness and also the requirement of eco-friendly initiatives in the present scheme of things, PMMA operates as a perfect alternative to glass inside the automotive glazing segment. As vehicle manufacturers push the bounds of design, also is automotive glazing evolving.
SUMIPEX® PMMA polymer offers characteristics that match the latest challenges inside the transportation sector. It’s a monumental challenge for car makers that are looking for to sit in recent environmental requirements and they are thinking about alternatives that reduce greenhouse gas and save fuel. Oahu is the perfect partner on this movement as it tends to make cars lighter.
As being a leading manufacturer of SUMIPEX® PMMA polymer, Sumitomo Chemical is happy to help you in understanding its properties and exactly how it ideal to automotive glazing.
