Faster and More Sustainable Charging

The transformation from the combustion to the electric engine entails several imponderabilities for the plastics industry. In part, electric drives have completely different material requirements which are becoming specifically evident with the increasing use of appropriate vehicles.

In electric vehicles, the change in engine technology also entails new requirements for the plastic materials used

Drivers of Electromobility

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.

Higher Performance in Water

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.

High Voltage in Cars

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?

A focal point of the Lanxess booth at the show this year will be materials for electromobility.

The demonstrator of a near-series- production housing for electric vehicle batteries is one of the highlights at  the Lanxess booth.

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.

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.

Polyamides: Electromobility and Sustainability Boost Developments

Dual Change with Polyamides

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.

Electromobility and Sustainability Are Driving Growth

At K 2022, it was clearly shown that with suitable materials not only can CO2 emissions be reduced, but also advantages in component design achieved.

The Japanese chemical company Asahi Kasei showed its concept vehicle at K 2022. The domed roof in particular could lead to a few changes in future automobiles.

With suitable materials CO2 emissions can be reduced and advantages in component design can be achieved.

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.

One of Ascend’s product ranges has demonstrated how the carbon footprint of PA can be reduced. The company has taken an additional stake in a recycler.

Instead of disposing of worn-out carpets in landfills or incinerators, recycling is a better alternative.

Old Carpets Become New Polymers

Orange has become the signal color of electromobility. Compounds based on PBT and PA are now available for high-voltage connectors.

In electromobility, orange is the color of choice, especially for high-voltage components.

Highly Exciting and Orange!

Ascend Performance Materials will focus on electromobility and sustainability at K. The company made this announcement at a press conference in advance of the trade show.

Ascend Performance Materials will focus on electromobility and sustainability at K. The company made this announcement at a press conference in advance of the trade show. Among its offerings will be polyamides (PA) and the PA precursors acrylonitrile and hexamethylene diamine, which are based on renewable raw materials. These are expected to be available from 2023.

The company will also unveil other PA innovations. These include Vydyne Thermaplus, a highly ductile PA66 that offers high resistance to long-term heat exposure. The material is claimed to be capable of replacing PA46. The Starflam product line is a UL-certified, flame-retardant PA that meets various performance requirements. Ascend will also showcase its growing range of long-chain PAs. It says that its HiDura series of PA610 and PA612 compounds outperform PA66 in terms of chemical resistance and abrasion performance.

On display, as well, will be applications that Ascend has developed in collaboration with vehicle manufacturers and suppliers with a view to enhancing the safety and performance of battery-electric vehicles. These are mainly based on hydrolysis-resistant and flame-retardant polymers.

One such development is a material for dampening unwanted vehicle and ambient noise in electric vehicles. Electric motors generate vibrations at ten times the frequency of those emitted by internal combustion engines. The dampening capacity of the materials used so far is not equal to this task. In Vydyne AVS, Ascend will demonstrate a PA66 that effectively dampens high-frequency vibrations directly at the motor and allegedly reduces cabin noise by up to 80 %.
