Replacing Metals with PPA Compounds

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.

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

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

Until now, laser welding of PPA has been considered problematic. This will change thanks to a collaboration between Envalior and LPKF Welding Equipment.

LDS types can also be laser welded. This opens up additional possibilities for function integration in PPA components.

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.

Two New Polyamide Grades Will Make Engineering Components More Cost-Effective

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.

Strong Trend towards Replacement of PA66 with PA6 Compounds

Polyamide 6 and 66 (PA6, PA66)

Replacing metal with polyamides (PA) in components can not only reduce weight and costs, but also offers developers greater design freedom. However, this requires materials with improved mechanical properties.

Metal Substitution with Improved PA

A new stabilization with heat resistance up to 190 °C protects against galvanic corrosion

Galvanic corrosion on electrical components should be avoided, especially in electric vehicles. Halogenide-free plastics are advantageous in this respect

Good Results despite the Pandemic

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.
