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.

 PA for a Front-End Carrier

Most of the energy in a crash is absorbed by metal parts. A new additional polyamide (PA) crash absorber has for the first time been integrated into the front end of the Mercedes-Benz S-Class. The advantage is that an additional loadpath could be added without significantly increasing the mass of the car.  Close cooperation between the project partners and the use of suitable simulation tools were key to successful realization of this project.

As part of the safety concept in the front end of the latest S-Class, Mercedes-Benz uses a crash absorber made from polyamide.

Accident Protection with Plastics

Electric-vehicle makers looking for fresh impetus are turning to thermoplastics, as these can be used to  improve the safety, performance and sustainability of the vehicles. Initial application areas for manufacturers can be found in a multitude of components ranging from battery cases to busbars, cooling lines and seals. Things become very interesting when material suppliers offer support in the form of CAE and injection molding analyses.

Thermoplastics play an important role in the batteries of electric vehicles. They help to keep battery temperatures in the optimal range for a long service life and high performance. 

Improving the Performance of Electric Vehicles with the Right Materials

Electric, Environmentally Friendly, Thermoplastic

The conditions in electric vehicles place high demands on the materials used. Therefore, automakers and suppliers must resort to expensive, high-performance plastics. For many applications, cost-effective alternatives are plastics whose properties have been greatly improved by means of treatment with high-energy electron beams.

Electromobility in particular, but also many other electrical applications, are asking for ever higher demands regarding the electrical properties of thermoplastics. This raises the question of whether the polymers commonly used in this area can still meet these demands. The plastics manufacturer, Lanxess, has now investigated how suitable, for example, polyamide and polybutylene terephthalate are for use at higher voltages and temperatures.

How Suitable Are PA and PBT for High-Voltage Applications?

Electrical and electronics manufacturers want to reduce greenhouse gas emissions from their products and optimize waste management and recycling for them. This can be achieved, among other ways, by using more sustainable thermoplastics and quality-assured recyclates. A close cooperation between companies to establish material cycles and the recycling-friendly design of equipment are also important.

BASF is expanding its portfolio of flame-retardant engineering plastics for electric vehicles. The new PA66 type Ultramid A3U44G6 DC OR is reinforced with 30 % glass fibers.

The new PA66 type is flame-retardant and meets all the criteria of color stability and heat aging resistance. This enables long-lasting color coding, which is safety-relevant in the sensitive area of high voltages in electric cars.

The combination of injection compression molding, direct coating and partial film insert molding enables a novel design for the front module of the BMW iX electric vehicle. Important in the development were extensive trials carried out by plastics manufacturer Covestro in its technical lab.

Various production processes are combined to manufacture the front module of the BMW iX, known as the kidney.

With the change from internal combustion engines to hybrid and electric vehicles, peak operating temperatures have dropped from 135 °C to 110 °C. At the same time, the number of operating hours compared to combustion engines has increased nine-fold. This has an influence on material selection.

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.
