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.

All 59 plastic body panels of the e.GO Life electric vehicle were thermoformed very cost-effectively from semi-finished plastic products i. e. coextruded plastic sheets

The global market for PMMA continues to benefit from an increasing demand, mainly from the construction and electronics industry as well as the automotive and transportation sector. However, continuing raw material bottlenecks have damped sales, which has also pushed up the price for PMMA.

Atomic force microscopy can be used to determine various properties of polymer surfaces. However, until now it was still necessary to change the hardware on the probe for different measurement methods.

With the Tosca series, all AFM measurements can be carried out with only one actuator body and thus without hardware exchange

More Design Freedom for Lights

The strong demand for PMMA is based on the continually expanding diversity of applications.

Design trend light: in the TIR lens LFO by Bartenbach and kdg Opticomp made of a Plexiglas PMMA of Röhm, the surface of the lenses is structured using free-form surface facets in such a way that the light appears homogeneous.

Concrete Building: Plastics Replace Plywood 

Until now, the sanitary market for bathtubs and shower trays has been dominated by steel, cast acrylic and ceramics. Frequent calls from consumers for more sophisticated designs, and the demand for lower costs in combination with consistently high production quality have meant that new materials such as coextruded ABS/PMMA sheet are becoming increasingly popular.

The computer model for designing slit dies and spiral manifold dies taking into account the entire flow path has been successfully transferred to industrial use. This model allows determination of the melt distribution in the individual die designs as a function of the flow properties of the melts being processed. The effects of the regions connected to the manifold channel, such as restrictor bars, parallel guides or relaxation zones are also included in the analysis.

Röhm produces antimicrobial PMMA for transparent partitions.

Transparent partitions are currently found everywhere. As a part of hygiene concepts, they provide protection against droplet infections with the coronavirus and other pathogens e. g. in supermarkets, restaurants or doctors’ practices. Plastics manufacturer Röhm presents a version of its polymethyl methacrylate (PMMA) Plexiglas specially developed for such partitions.

The transparent solid sheets feature a coating on both sides which combines its resistance to scratches and chemicals with an antimicrobial effect, making it suited for use in areas with heavy public traffic.

“The awareness of hygiene has changed for good. That is why we have further enhanced our product range with a special version of our original, which satisfies these increased demands,” says Falk Majert, Head of the Acrylic Products business unit at Röhm.
