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

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

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 

Plastics processors have a wide range of colors at their disposal to color their products. Choosing the right color can ultimately be the key to success. But colors are just as subject to trends as materials and designs. Kunststoffe asked manufacturers of pigments, masterbatches, and colorants which colors would be particularly popular in the coming year.

What Will Be the Color of 2021?

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.

Bio-based plastics can lock away vast quantities of CO2 in durable, recyclable applications and make a real contribution to climate protection. All that is needed for this is the right product design and a functioning circular economy. By focusing more on this approach, the plastics sector has the chance to evolve into a key industry of a green economy.

Two new inorganic yellow pigments based on iron oxide and zinc oxide respectively are designed for coloration in a temperature range of between 220 and 260 °C.

Yellow for High Temperatures

For many components, the use of metal-replacing plastics is an attractive possibility e. g. to save weight and benefit from enhanced design freedom. In various applications, however, the thermal conductivity of the polymers is of equal importance. There are different additives that can be used to enhance this property. In the development of two polyamide families, Domo Engineered Materials investigated which of those additives are especially useful to this end, and applied Light Flash Analysis to examine the materials.

Heat Transfer with Plastics versus Metals

The circular economy, electromobility and the continuing corona pandemic are influencing color selection for plastics. Kunststoffe asked colorant manufacturers about the resulting color trends. We also wanted to know what effects the increased use of recyclates is having and the extent to which manufacturers are affected by the present supply bottlenecks.

Colored Mood Enhancers

At Fakuma, Granula presents masterbatches specially tailored to more sustainable plastic products. For this purpose, the company has developed grades with biological pigments and degradable additives for injection molding and extrusion.

Once known for rubbers, Lanxess has switched its focus in the last two years to engineering plastics, chemical intermediates and specialty chemicals. This transformation led to the founding of the joint venture, Arlanxeo, that will be celebrating its premiere at the K. The technical achievements are concentrated at present on the automotive industry and on electrical and electronics applications.

Restructured and with a New Look 

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).
