Electrical architecture in an E-car is significantly more challenging than for conventionally powered vehicles. Particularly for insulation of high-voltage (HV) components, the demands on the materials used are increasing. With specially-tailored materials for electric vehicles, challenges in automotive high-voltage technology can be overcome.

The e.GO Life is an affordable electric car for short-range transport. Starting as a development project at the RWTH Aachen University campus, the first cars of this type were delivered in the middle of this year. For this car, the engineers use plastic panels for the vehicle’s body. The large-sized body panels are thermoformed by the plastics-processing company Parat in close collaboration with the plastic sheet manufacturer Senoplast.

The transition to electric cars is transforming automotive design. And so polymers producer Röhm has developed special polymethyl methacrylate (PMMA) molding compounds with this in mind. These are sold under the company’s well-known Plexiglas brand. At Fakuma, the company will be demonstrating how they can be used to combine design requirements and functional properties.

Large, brand-specific combination rear lamps are on trend in the automotive industry. These are implemented with the aid of different components, such as covers and light guides. Röhm believes that they can be made from transparent and diffuse light scattering PMMA molding compounds. To an extent depending on the grade, the molding compounds have high color stability, transparency and good scattering properties combined with low transmission loss. The company offers them in different formulations and colors.

Also on display will be PMMA Plexiglas Optical HT. This material has been developed specifically for use with high-performance LEDs. Until now, this often required a compromise between high optical purity and heat deflection stability. Röhm claims, however, that the molding compound meets both requirements. It is said to ensure very good optical quality, even at elevated continuous service temperatures, and so offers the automotive and lighting industries greater scope in their product design.

For meeting even higher heat requirements, the polymers manufacturer has developed Pleximid TT50 HF, a polymethyl methacrylimide (PMMI). Röhm says it also features greater flow capability and is therefore suitable for very fine structures.

Unlike internal combustion engines, the motors of electric cars are no longer dependent on a cooling air flow. For this reason, the eye-catching grille on the front of vehicles can make way for other elements, such as illuminated emblems, other lighting elements and sensor covers. Rugged plastic elements are in high demand for all of these applications. Materials at the front end and in the lower car body are exposed to demanding mechanical stresses. For this application, Röhm will be presenting impact-modified PMMA special molding compounds at the trade show that, it says, can withstand these stresses. Due to its balanced property profile, the PMMA is a rugged, cost-efficient alternative for many components that would otherwise require coating, adds the company.

In addition to automotive applications, Röhm will also be showcasing materials for household appliances. Here, the company offers, for instance, PMMA for displays that have a black panel effect. These are not recognizable as screens when switched off, but function normally as displays as soon as they are switched on. For this technology, Röhm offers special molding compounds in neutral gray colors. PMMA molding compounds can also be used for surface finishing of household appliances. According to the company, they provide a high-quality appearance and extend the durability of the product.
