Polycarbonate had earned the tag since the the most suitable material to be used inside the automotive industry. However, these days, Polymethyl Methacrylate, the PMMA polymer or commonly known acrylic plastic, has efficiently risen towards the growing demands of the automotive industry in replacing polycarbonate for important used in the, namely, automotive glazing.

Long established to be used in several vehicle applications like decorative trim, ambient lighting and door entry strips, automotive glazing is among those fields offering the very best growth risk of PMMA.
Related key popular features of acrylic plastic which make it perfect for the whole process of automotive glazing are discussed below.
Transportable
To generate a comparison with a very basic level, PMMA is half the body weight plus more transparent than glass, thereby providing superior visibility even during the case of fluctuating and unstable temperatures. Due to its molecular structure, thermoformed thermoplastic resin are used almost exclusively for car window glazing where every one of the necessary requirements for light-weight materials which might be safe, simple to process and perform in most weathers are met.
On top of Scratch Resistance
Another essential requirement of glazing is scratch resistance. Standard PMMA already contains the highest surface hardness of most thermoplastics even if uncoated. However, for automotive glazing, you can find stringent conditions to become fulfilled to satisfy the ideal state of scratch resistance. The use of a coating is thus mandatory. Considering that PMMA is intrinsically UV and also weathering-resistant, a single-step coating is successful. As opposed, thermoplastics which have low capacity weathering need a two-step coating system. This results in relatively expensive for coating.
New design possibilities
PMMA glazing is Forty to fifty percent lighter than conventional glass, which piques a persons vision of automobile manufacturers. Using the advantages being immediately obvious, PMMA is currently known as the best fit for automotive glazing. Weight savings apart, the transparency of acrylic plastic in addition to its very 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 which works as a major benefit over other thermoplastics like polycarbonate, which has been primarily useful for glazing in the past. Compared with traditional materials like polycarbonate, moulded PMMA, provides a distinct chance of functional integration – reducing recess depth and assembly costs.
Environment-friendly
The brand new goal inside the automotive industry is to develop clean low fuel consumption vehicles. Because of the awareness and also the requirement of eco-friendly initiatives with the current economic scheme of things, PMMA works as a perfect substitute for glass inside the automotive glazing segment. As vehicle manufacturers push the boundaries of design, so too is automotive glazing evolving.
SUMIPEX® PMMA polymer offers characteristics that meet the latest challenges inside the transportation sector. It’s a monumental challenge for car makers that are looking for to adjust to recent environmental requirements and they are contemplating alternatives that reduce greenhouse gas and save fuel. Oahu is the perfect partner within this movement given it can make cars lighter.
Like a leading manufacturer of SUMIPEX® PMMA polymer, Sumitomo Chemical is satisfied to help you in understanding its properties and the way it most suitable to automotive glazing.

Polycarbonate had earned the tag since the the most appropriate material for use inside the automotive industry. However, these days, Polymethyl Methacrylate, the PMMA polymer or commonly known acrylic plastic, has efficiently risen for the growing demands with the automotive industry in replacing polycarbonate for important used in a, namely, automotive glazing.

Long established for use in many different vehicle applications like decorative trim, ambient lighting and door entry strips, automotive glazing is one of those fields that provide the very best growth potential for PMMA.
Related key options that come with acrylic plastic that make it perfect for the operation of automotive glazing are discussed below.
Lightweight
To make a comparison on the simple level, PMMA is half the load plus much more transparent than glass, thereby providing superior visibility even just in true of fluctuating and unstable temperatures. As a result of its molecular structure, thermoformed polymer resin have become used almost mainly for car window glazing where all the necessary requirements for light-weight materials which are safe, an easy task to process and perform in all of the weathers are met.
High on Scratch Resistance
Another essential dependence on glazing is scratch resistance. Standard PMMA already has the highest surface hardness of most thermoplastics even when uncoated. However, for automotive glazing, you will find stringent conditions to be fulfilled to meet the best state of scratch resistance. The use of a coating is therefore mandatory. Considering that PMMA is intrinsically UV along with weathering-resistant, a single-step coating works well. In contrast, thermoplastics who have low capacity weathering require a two-step coating system. This leads to relatively expensive for coating.
New design possibilities
PMMA glazing is 40 to 50 percent lighter than conventional glass, which piques the eye of automobile manufacturers. Together with the advantages being immediately obvious, PMMA is known as the correct fit for automotive glazing. Weight savings apart, the transparency of acrylic plastic as well as its high weathering resistance, pleasant acoustic properties, and exceptional form ability allow freedom enabling entirely new design possibilities.
Less stress birefringence
PMMA exhibits hardly any stress birefringence which functions as a major benefit over other thermoplastics like polycarbonate, which has been primarily employed for glazing previously. In contrast to traditional materials like polycarbonate, moulded PMMA, supplies a distinct chance of functional integration – reducing recess depth and assembly costs.
Environment-friendly
The new goal inside the automotive market is to produce clean low fuel consumption vehicles. In the awareness along with the requirement for eco-friendly initiatives with the current economic scheme of things, PMMA functions as a perfect alternative to glass inside the automotive glazing segment. As vehicle manufacturers push the bounds of design, so too is automotive glazing evolving.
