Despite Raw Material Shortages, the Signs for PMMA Point to Growth

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.

Polymethyl Methacrylate (PMMA)

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.

Greater Design Freedom for Electric Cars

Electric vehicles can be charged not only at charging stations, but also wirelessly. Here, the energy exchange takes place between an induction coil positioned in the ground and a receiver coil mounted in the e-car.

Wireless charging could increase the range, and therefore the acceptance of electromobility.

More Comprehensive  Life Cycle Analysis

Due to the climate change, new fields of development and sustainability topics have come into focus along the added-value chain.

Polyamide continues to be one of the most important technical plastics in the automotive sector, where it enjoys widespread use. This not only applies for classical internal combustion vehicles, but in terms of volume will also be the case for electric vehicles.

The global market for PBT has recovered well from the aftermath of the corona pandemic. However, there is a lot going on among manufacturers at the moment.

PBT compounds are very much in demand for electromobility, including for parts of the battery, electric transmission and the charging infrastructure.

Suitable Materials for Smart  Vehicle Design

Long fiber thermoplastic compression molding is suitable for the production of components with large surfaces such as battery enclosures for electric vehicles. However, these components place high demands on the material used.

Large-area components, like the battery cover shown, can be produced very well using direct long fiber compression molding. Optimized materials such as PA66 Mobius NPD 555 FR GF50 from Invista  are ideal for the process involved.

Two resin grades developed for long fiber thermoplastic compression molding permit the substitution of thermosetting SMC molding materials.

Special plastics are needed for the increasingly widespread 800 V drives of electric cars. Bio-based PPA, for example, represents a sustainable option.

Faster and More Sustainable Charging

PMMA for lights, lighting solutions, automotive exteriors, and household appliances will take center-stage on Röhm’s booth at this year’s show.

Röhm will be showcasing its latest development in PMMA, Plexiglas Optical HT. This material obviates the need for converters to choose between high optical quality and high long-term service temperatures, as it meets both requirements. It is therefore suitable for, e.g., high-power LED lenses and long light guides.

Röhm has also further developed its range of specialty molding compounds for automotive taillights. Aside from colorless transparent PMMA or PMMA pigmented in signal colors, the company offers diffuse light-scattering variants whose light-scattering properties and transparency vary in accordance with the product. The manufacturer says that the molding compounds can also be easily processed by special methods, such as laser-welding. This expands the scope for taillight design, because it allows angular components to be combined with minimal joints.

Röhm will also come to the show with specialty PMMA molding compounds for the front of vehicles. This is the company’s response to current advances in automobiles. Long light guides as well as high-gloss decorative trim and emblems are replacing chrome in the front areas of vehicles. This application calls for particularly rugged, impact-modified materials.

Röhm believes that PMMA Plexiglas Resist AG 100 is ideal for illuminated automotive applications because it meets the necessary optical and mechanical requirements. Meanwhile, Plexiglas Hi-Gloss NTA-5 can be used for high-gloss panels. According to the company, this can be used to implement both rugged and resource-efficient alternatives to components that otherwise need downstream painting. The material’s high weatherability ensures a lasting, sophisticated appearance.

In the realm of household goods, Röhm will be presenting molding compounds suitable for permanently high-gloss surfaces, illuminated designs and operating panels, and displays with a black panel effect that integrate seamlessly into the housing. With these displays, only a high-gloss black panel is visible when the appliance is off.
