Replacing Metals with PPA Compounds

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.

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.

DSM sells its Engineering Polymers business to Lanxess and the financial investor Advent. In return, the two companies are setting up a joint venture to which Lanxess is also contributing its PA and PBT business.

Lanxess is outsourcing its engineering plastics business to the joint venture.

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.

Engineering and high-performance plastics as alternatives to metals will be one of the highlights at Lehvoss’s booth.

Focus on Metal Substitutes

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.

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.

Wide Range of PA Innovations

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.

Faster Process to Safe Battery Enclosures

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

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 wide-ranging and specific property modifications, plastics can take more and more applications away from classic metal components. Polyamides and polyphthalamides, in particular, also are extending the performance spectrum, as two new variants show.

Progressive Metal Replacement

The worldwide market situation differs widely for PA6 and PA66. While demand and capacities for PA6 precursors and base polymers are balanced, supply shortages occur frequently for PA66, and in particular its precursor adiponitrile (ADN). This leads to partially drastic price increases. Therefore, a growing number of users is searching for PA66 alternatives.

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.

At K, RadiciGroup High Performance Polymers will present various examples to demonstrate how environmentally friendly and traceable products can be implemented in suitable polymers. It will concentrate on the company’s Renycle product family. These engineering compounds have a variable proportion of mechanically recycled PA obtained from PIR and PCR. To keep the product properties as constant as possible from batch to batch, Radici says it relies on careful selection of the constituent raw materials.

According to the company, in addition to information about the products’ physical, mechanical and electrical properties, customers will receive a life cycle analysis of the products’ environmental impact and how it compares with that of virgin materials. This will allow customers to accurately measure and make meaningful claims about the sustainability of their own products.

Radici will also be introducing a range of PA610-based products, some of which are made from renewable raw materials. According to the company, these can represent a genuine alternative to plastics from fossil sources for many applications requiring high chemical resistance and dimensional stability. In addition, the company has developed materials designed to optimize the thermal properties of buildings and improve the reliability of solar panel systems over the long term. The plastics manufacturer has also announced news about materials which have been approved for contact with drinking water.

Also on display at the booth will be compounds aimed specifically at electromobility. Radici believes that these help to reduce weight and increase product safety. They include heat-resistant, orange-colored compounds for high-voltage applications. The company will also show specific examples of how CAE simulations can be used to replace metals.
