5 Explanations why Acrylic Plastic Is employed For Automotive Glazing

Polycarbonate had earned the tag because the the most appropriate material for usage from the automotive industry. However, in recent years, Polymethyl Methacrylate, the PMMA polymer or commonly known acrylic plastic, has efficiently risen to the growing demands in the automotive industry in replacing polycarbonate which are more important utilization in the market, namely, automotive glazing.

Long established for usage in a number of vehicle applications such as decorative trim, ambient lighting and door entry strips, automotive glazing is just one of those fields that provide the greatest growth risk of PMMA.
Related key top features of acrylic plastic that make it perfect for the operation of automotive glazing are discussed below.
Transportable
To make a comparison on the simple level, PMMA is half the body weight plus much more transparent than glass, thereby providing crystal clear visibility even during the truth of fluctuating and unstable temperatures. Owing to its molecular structure, thermoformed methyl methacrylate resin are now used almost only for car window glazing where all the necessary requirements for light-weight materials which might be safe, easy to process and perform in every weathers are met.
At the top of Scratch Resistance
Another important desire for glazing is scratch resistance. Standard PMMA already has the highest surface hardness coming from all thermoplastics regardless if uncoated. However, for automotive glazing, there are stringent conditions to be fulfilled in order to meet the optimal state of scratch resistance. The application of a coating is therefore mandatory. Given that PMMA is intrinsically UV as well as weathering-resistant, a single-step coating is useful. In comparison, thermoplastics who have low potential to deal with weathering need 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 a person’s eye of automobile manufacturers. Using the advantages being immediately obvious, PMMA is currently considered the best fit for automotive glazing. Weight savings apart, the transparency of acrylic plastic in addition to its extremely 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 and also this operates as a major benefit over other thermoplastics such as polycarbonate, that has been primarily used by glazing during the past. Weighed against traditional materials such as polycarbonate, moulded PMMA, provides a distinct potential for functional integration – reducing recess depth and assembly costs.
Environment-friendly
The newest goal from the automotive marketplace is to formulate 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 replacement for glass from the automotive glazing segment. As vehicle manufacturers push the bounds of design, so too is automotive glazing evolving.
SUMIPEX® PMMA polymer offers characteristics that satisfy the latest challenges from the transportation sector. It’s a monumental challenge for car makers that are looking for to sit in recent environmental requirements and are thinking about alternatives that reduce greenhouse gas and save fuel. It’s the perfect partner with this movement because it can make cars lighter.
