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?

A trade show highlight of masterbatch manufacturer Lifocolor will be its biodegradable plant-based color concentrates. These are claimed to enable a closed-loop system for biodegradable plastics.

When it comes to long-term closed-loop recycling, it is not only the plastics that matter, but also the colorants employed. Lifocolor has developed masterbatches specifically for coloring recycled materials.

Colored plastics are not just a marketing gimmick, but fulfill important functions with technical components. In particular, they warn of hazards and permit the fast and direct identification of components. However, when coloring such plastic components, the processors are faced with several difficulties. For example, the colorants used must exhibit long-term resistance to high temperatures and must not impair the polymer’s mechanical properties. Therefore, when selecting the colorant, compounders and processors must observe several important points.

Colors for the High-Performance Sector

Bioplastics, biodegradable plastics and recyclates pose individual demands on colorization. BASF SE, Ludwigshafen, Germany, presented Sicoversal B, a biodegradable masterbatch for coloring compostable plastics. With this product, bioplastics can be colored in an environmentally friendly manner.

Sustainable development is the focus of the Israeli company Tosaf’s trade show presence. The company presents functional, color and combined masterbatches for processing by extrusion and injection molding. These will include color masterbatches for recyclates with a special focus on post-consumer plastics as well as biodegradable masterbatches.

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.

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.

The increasing demand for recyclates and the shortage of food-grade PET flakes pose challenges for batch quality and color consistency.

Repi offers various additives for recycling PET, which can be used, for example, to prevent the material from darkening.

Vitamins for the Circular Economy

The quality of recyclates is seen as too low. Improvements are possible by using additives, as was shown by the exchanges during the Forum Plastic Recyclates.

Quite clearly, the central theme of this year’s conference  was additives for recycling materials.

At the start of the year, Toray opened a European R&D center near Munich, Germany, dedicated to automotive applications. From specially manufactured carbon fibers and engineering plastic compounds to battery elements such as separator foils, a wide portfolio is on offer from a single source. Kunststoffe spoke to Toray Group managers about their evaluation and strategy.

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

The circular economy and more sustainable additives are the focus of AF Color’s Fakuma presence this year.

The masterbatch manufacturer is presenting, for example, its carbon black-free masterbatches of the IR product line. The plastics pigmented with them can be detected via near-infrared spectroscopy (NIR).

In addition, the company is presenting bio-based and biodegradable additives developed together with its subsidiary Bio-Fed. They include an odor absorber. These additive batches are marketed under the name AF-Eco.

The company is also showing additional color shades for high-temperature polymers. They include an intensive orange for the field of electromobility, which is intended for pigmenting polyamide (PA).
