5 Logic behind why Acrylic Plastic Is utilized For Automotive Glazing

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

Long established for use in a number of vehicle applications including decorative trim, ambient lighting and door entry strips, automotive glazing is one kind of those fields that offer the best growth possibility of PMMA.
Related key options that come with acrylic plastic which make it suitable for the operation of automotive glazing are discussed below.
Transportable
To produce a comparison over a erogenous level, PMMA is half the extra weight and much more transparent than glass, thereby providing magnificent visibility even just in the situation of fluctuating and unstable temperatures. As a result of its molecular structure, thermoformed Acrylic Plastic have become used almost only for car window glazing where each of the necessary requirements for light-weight materials which can be safe, simple to process and perform in most weathers are met.
High on Scratch Resistance
Another important requirement for glazing is scratch resistance. Standard PMMA already has got the highest surface hardness of most thermoplastics regardless if uncoated. However, for automotive glazing, you will find stringent conditions to be fulfilled to meet the optimal state of scratch resistance. The effective use of a coating is thus mandatory. Given that PMMA is intrinsically UV and also weathering-resistant, a single-step coating is effective. In contrast, thermoplastics that have low potential to deal with weathering require a two-step coating system. This leads to relatively expense for coating.
New design possibilities
PMMA glazing is 40 to 50 percent lighter than conventional glass, which piques the eye of automobile manufacturers. Using the advantages being immediately obvious, PMMA has become known as the correct fit for automotive glazing. Weight savings apart, the transparency of acrylic plastic as well as 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 and this operates as a major benefit over other thermoplastics including polycarbonate, that was primarily used by glazing before. In contrast to traditional materials including polycarbonate, moulded PMMA, comes with a distinct chance for functional integration – reducing recess depth and assembly costs.
Environment-friendly
The newest goal from the automotive companies are to develop clean low fuel consumption vehicles. In the awareness and the requirement of eco-friendly initiatives in the current scheme of things, PMMA operates as a perfect replacement for glass from the automotive glazing segment. As vehicle manufacturers push the boundaries of design, also is automotive glazing evolving.
