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.

Against the Current

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.

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.

At K, Radici will present the Renycle product family. These engineering compounds have a variable proportion of mechanically recycled PA obtained from PIR and PCR.

Reducing weight and ensuring safety are the aims of compounds developed by Radici specifically for electromobility.

More Comprehensive  Life Cycle Analysis

Compounder Mocom will focus chiefly on technical compounds for WiFi and radar applications as well as on fuel cell and battery technology.

Applications for the light-transmitting PC compounds with metallic effect include illuminated trim.

Compound Innovations for Trade Show Debut

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.

Bio-Fed’s booth will be dedicated to the topic of bioplastics in all their facets, and will be run jointly with Akro-Plastic, AF-Color and parent company K. D. Feddersen.

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.

The K 2022 offered an immense range of innovations and application examples for – and with more – sustainable materials. Interestingly hereby was that bio-based versions were extremely popular.

Shoes made from waste gas: genetically modified bacteria produce ethanol from waste gas, which is then used to create plastic, e.g. for the Cloudprime shoes from On.

Is Bio the New Standard?

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

For a specially good combination of toughness and stiffness, even in high-temperature applications, the TER Plastics Polymer Group, Herten, Germany, is exhibiting its Terez LFT range of grades with good fiber adhesion at the Fakuma trade show. A new product in the range, which usefully complements existing long fiber compounds, is Terez GT3 HLG40 with reduced water absorption. Tribological requirements, even at high temperatures, can be fulfilled with the newly developed grade Terez HT 100 H G30 TF15. According to the manufacturer, special chemical coupling of the lubricating component allows maintenance-free use over long periods. With standard polyamides, glass fiber contents of up to 65 % are now available, which enable high stiffness and strength as well as good surface quality to be achieved.

Range of LFT Compounds Expanded 

Lightweight is no longer just a matter of replacing metal. More and more often, plastics already in use are substituted by lighter weight polymers. New low-density compounds exhibit not only good materials and processing properties. On top of that, they offer various secondary advantages, such as are illustrated by an engine room bulkhead cover and a car door sill.

Wide Range of Materials at a Shared Booth

Polymers distributor K. D. Feddersen will be presenting various new materials at the Fakuma trade-show which it will be sharing with other companies in the group.

 The materials include various unreinforced, reinforced, impact-modified and flame-retardant PA66 grades from Ascend Performance Materials. Also on display will be the product families added by Celanese in March for the medical sector, namely Hostaform (POM), Vectra (LCP), Celanex (PBT) and Fortron (PPS).

The distributor will be presenting materials for the electric mobility sector as well. Thermal management plays an even greater role in these electric drives than it does in internal combustion engines. According to K. D. Feddersen, Hostacom EKG 2087T, a PP co-polymer from LyondellBasell, is suitable for this area. It is reinforced with 30 % chopped strands and is said to have much higher creep resistance than standard grades.

The company will also be showcasing its expanded range of materials obtained from sustainable sources. These include polymers from Celanese, Trinseo, Aurora Kunststoffe and Bio-Fed. Among these are biobased and biodegradable polymers, as well as recycled materials from post-industrial and mass-balanced sources. Bio-Fed’s M Vera GP series of compounds, for example, is intended for injection molding. They are virtually 100  % bio-based and suitable for food-contact applications. The company also has biocompounds for film extrusion that can be converted into fruit and vegetable bags. Special soil-degradable grades for mulch films will be on display at the booth too. Also at the show, Akro-Plastic, a compounder within the group, will be presenting Akromid Next G, a biobased material. This density-reduced compound is based on PA69 and has a content of bio-circular PP and recycled carbon fibers. It is aimed at the cooling water circuits of electric vehicles, and other applications.

AF-Color, a masterbatch maker within the Feddersen Group, will be showing its latest developments at the shared booth as well. Its product range for high-temperature polymers features color shades for coloring polyamide, such as a bright orange for electric mobility applications.
