Search engine for touristic excursions to any place in the world Polycarbonate had earned the tag because most suitable material for usage within the automotive industry. However, in recent times, Polymethyl Methacrylate, the PMMA polymer or commonly known acrylic plastic, has efficiently risen for the growing demands in the automotive industry in replacing polycarbonate for the most important use in the market, namely, automotive glazing.
Long established for usage in a variety of vehicle applications including decorative trim, ambient lighting and door entry strips, automotive glazing is among those fields that supply the very best growth risk of PMMA.
Related key popular features of acrylic plastic which render it perfect for the process of automotive glazing are discussed below.
Light-weight
To produce a comparison on a standard level, PMMA is half the load plus more transparent than glass, thereby providing really clear visibility even in the situation of fluctuating and unstable temperatures. As a result of its molecular structure, thermoformed sumitomo chemical asia are now used almost exclusively 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 critical dependence on glazing is scratch resistance. Standard PMMA already contains the highest surface hardness of all thermoplastics even though uncoated. However, for automotive glazing, you’ll find stringent conditions to become fulfilled in order to meet the perfect condition of scratch resistance. The effective use of a coating is therefore mandatory. Considering that PMMA is intrinsically UV along with weathering-resistant, a single-step coating is successful. In contrast, thermoplastics which have low capacity weathering have to have a two-step coating system. This brings about 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 now known as the correct fit for automotive glazing. Weight savings apart, the transparency of acrylic plastic along 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 very little stress birefringence this also operates as a major benefit over other thermoplastics including polycarbonate, that was primarily used by glazing previously. Weighed against traditional materials including polycarbonate, moulded PMMA, supplies a distinct potential for functional integration – reducing recess depth and assembly costs.
Environment-friendly
The newest goal within the automotive industry is to produce clean low fuel consumption vehicles. Because of the awareness and also the requirement of eco-friendly initiatives in the present scheme of things, PMMA operates as a perfect substitute for glass within the automotive glazing segment. As vehicle manufacturers push the boundaries of design, so too 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 therefore are contemplating alternatives that reduce greenhouse gas and save fuel. Oahu is the perfect partner with this movement given it helps make cars lighter.
As being a leading manufacturer of SUMIPEX® PMMA polymer, Sumitomo Chemical is glad to help you out to understand its properties and just how it suitable to automotive glazing.
