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.

After the explosion of developments in polymer formulations over the last year, it is worth taking a closer look during Fakuma at details such as functional additives or application-specific modifications. Overall, lightweight design continues to spur development but defined surface characteristics are also in demand. The reported innovations do not just follow current consumer trends but also provide ideas for advanced product and process developments.

Polymers Can Be Expected Everywhere 

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.

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.

Masterbatches for Current Trends

The conditions in electric vehicles place high demands on the materials used. Therefore, automakers and suppliers must resort to expensive, high-performance plastics. For many applications, cost-effective alternatives are plastics whose properties have been greatly improved by means of treatment with high-energy electron beams.

Colors can turn plastics products into real eye-catchers. Kunststoffe asked colorant manufacturers to predict which colors will be trending in the coming year.

Trend Report on the Coloring of Plastics

Garish or Necessarily Plain?

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.

The HolyGrail 2.0 Initiative aims to improve the sorting of plastic waste. But the method also has certain drawbacks. Here, luminescent pigments provide an alternative.

Marker masterbatches enable different information to be embedded in plastics. This can be used to improve the recycling circle.

Luminous Markers instead of Holy Grail

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.

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 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).
