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.

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.

A large proportion of the world’s polycarbonate is processed in Asia, especially in China. This is why capacity expansions are mainly taking place there.

PC-based films enable attractive designs in automobile interiors. Electroplated real metal surfaces with touch sensors are a real eye-catcher, no matter whether the backlighting is switched on or off.

Lightweight construction, functionality and design are characteristic of material development in all areas of application for PC compounds, composites and films. The range of materials has enormous opportunities when it comes to the mobility of the future, lightweight structural construction with continuous fiber-reinforced composites, 5G technology and medical technology.

In electric vehicles, the original function of the radiator grille, namely to supply air to the engine, is no longer needed. It can therefore be used entirely as a design element, for example by integrating luminous logos and fade-out effects

Polymaker will offer the Polymaker PC-r 3D printing filament made from recycled polycarbonate (PC). The PC for the filaments comes from materials supplier Covestro and consists of a combination of recycled plastic waste and virgin material.

The combination of recyclates and virgin material reduces the carbon footprint of the polycarbonate and still allows it to be extruded into filaments

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.

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.

Green Electricity and Renewable Feedstock

Covestro Produces Climate-Neutral Polycarbonate

Selected Makrolon RE grades from Covestro are climate-neutral from cradle to gate, thanks to the usage of renewable electricity for Covestro production processes and the introduction of raw materials coming from mass-balanced bio-waste and residues.

Covestro offers climate-neutral polycarbonate (PC). Selected Makrolon RE grades are climate-neutral from cradle to gate, thanks to the usage of renewable electricity for production processes and the introduction of raw materials coming from mass-balanced bio-waste and residues.

Since receiving the ISCC Plus mass balance certification for two of its European sites at the end of 2020, Covestro has been supplying polycarbonates partly sourced from renewable feedstock. They are attributed via the mass balance approach and lead to a significant carbon footprint reduction. The company has acquired Guarantee of Origin certificates from unsubsidized photovoltaic renewable electricity plants located in Germany for its Uerdingen plant. They are allocated to the specific electricity needs of selected mass-balanced products for both chlorine electrolysis – essential to the production of polycarbonate – and other process steps. As a result, selected Makrolon RE grades become climate-neutral.

“This is an important milestone towards our vision to be fully circular,” says Lily Wang, Head of the Engineering Plastics segment at Covestro. “We have taken a big step forward to help our customers meet their sustainability targets, by offering a climate-neutral product that is at the same time a drop-in solution to speed up the transformation towards a circular future.”

The PCs produced in this way are said to have the same properties as fossil-based polycarbonates. According to the company, they can be manufactured without modifying production processes and workflows. The company is also stepping up efforts to source more renewable energy to power its sites. In 2019 Covestro signed the world’s largest corporate supply contract with Ørsted for offshore wind energy to cover a considerable part of its electricity demand in Germany with wind energy from the North Sea starting 2025. Additionally the company has signed a supply agreement with Engie for green power in Belgium to cover 45% of the electricity demand of the Antwerp site from new onshore and wind turbines.

For the production of its climate-neutral polycarbonates Covestro uses mass-balanced renewable feedstock and renewable energies.
