Automotive plastic glass into the focus of industry attention
In recent years, automotive plastic glass has gained significant attention. While many car manufacturers have been cautious about marketization, the benefits of lightweight design and energy efficiency have proven too tempting to ignore. Collaborating with material suppliers, automakers are exploring innovative solutions that can be applied to their own vehicle models. One such example is the partnership between SAIC E50 and Evonik’s PLEXIGLAS materials.
At the 2014 Chinaplas exhibition, the SAIC E50 was showcased at the Evonik booth, drawing a lot of interest from visitors. According to the company's representatives, the rear window and fixed triangular window of this model were made using Evonik’s PLEXIGLAS plastic. The material's smooth texture and elegant curves seamlessly blended with the refined design of the E50, highlighting its aesthetic and functional advantages.
Freeform designs are becoming increasingly popular in the automotive industry, as designers aim to create unique shapes while improving aerodynamics. PLEXIGLAS automotive plastic glass offers designers almost unlimited flexibility, allowing them to produce highly curved or angularly shaped components. Compared to traditional glass, it is more easily molded through injection molding and thermoforming, making assembly simpler and more efficient. This enables the creation of complex, integrated parts that combine multiple functions—such as a non-movable fixed triangle window that includes a black pillar trim and an integrated taillight system. These multi-functional components not only enhance visual appeal but also reduce installation steps and overall weight.
Weight reduction is one of the most critical factors in modern vehicle design. Lighter vehicles consume less fuel and emit fewer pollutants, which is especially important for internal combustion engine cars. For electric vehicles, where battery weight plays a major role, reducing the overall mass of the vehicle is even more crucial. PLEXIGLAS automotive plastic glass is approximately 40-50% lighter than conventional glass while maintaining durability. This lighter weight helps lower the vehicle’s center of gravity, improving handling and stability, especially on uneven terrain.
Beyond weight savings, PLEXIGLAS also offers environmental benefits. Its life cycle assessment shows better performance compared to other glass materials like laminated or tempered safety glass. This evaluation considers energy use and CO₂ emissions throughout the material’s lifecycle, from production to recycling. As a result, PLEXIGLAS supports sustainable manufacturing practices and aligns with global efforts to reduce environmental impact.
With its promising potential in automotive applications, Evonik is expanding its development lines to provide customers with a wide range of options. The company is working on both single-layer and multi-layer systems tailored for different vehicle components. Various single-layer systems, including those with scratch-resistant coatings for side windows, rear windows, and sunroofs, have already received ECE R 43 certification and are being used in several prototypes, including the SAIC Roewe E50. Other examples include the modern Ioniq concept car and the electric microMAX concept by Swiss think tank Linsbide, both featuring full windows made from PLEXIGLAS automotive plastic glass.
These concept vehicles represent just a glimpse of the transformative power of innovation in the automotive industry. Evonik is committed to advancing research and development to meet the evolving needs of car manufacturers. In 2014, the company began exploring new impact-modified molding materials for plastic glass, aiming to expand process flexibility—from thermoforming to injection and compression molding. The continued development of PLEXIGLAS automotive plastic glass marks a significant milestone in the evolution of automotive materials and design.
High Frequency Laser Ranging Sensor
The module operates with a laser wavelength of 905 nanometers, falling within the near-infrared spectrum, which ensures minimal transmission loss in the atmosphere and poses negligible risk of harm to human eyes. Laser sensors with a 700-meter (standard specs) range typically offer high accuracy and extensive ranging capabilities, making them well-suited for applications requiring long-distance measurements. These sensors find widespread use in military, aerospace, surveying, geological exploration, and other related fields.
