According to the designers at GRAFE Blankenhain, the “haute couture” of individual color and surface design of plastics consists of adding contrasting fibers or plastic particles to the desired base color. The result is customized surfaces and structures that raise product design possibilities to a new level.
In the automotive sector, manufacturers’ concept cars demonstrate this new trend. “Bumpers, sills, underride guards or wheel arch liners that appear to be made of stone with their marbled look are all the rage, especially for SUVs,” reports Danny Ludwig, Head of Product Management, Color & Functional Masterbatches. “There is a lot of demand from German and French OEMs, specifically for exterior parts.”
The first components have already been realized with GRAFE’s masterbatches at parts suppliers and have met with great approval, Ludwig says. “Flakes and fibers of different structures are incorporated into the batch. What’s completely new is that this can now also be realized with automotive-grade PP grades with a high recycled content, thus going some way toward fulfilling the sustainability promise.”
The main plastics for which the newly developed effects are used are PP for exterior and PC/ABS for interior applications. A 20 to 30 percent recycled content in PP is currently possible while still meeting the high demands placed on plastics regarding durability, emissions, component mechanics, and quality.
“For automotive manufacturers, black and gray are the most interesting, but for other industries, many colors are possible.” Whether flower pots, furniture, caravans, or toys. The applications are endless, Ludwig says.
The development and identification of new raw materials that are suitable as additives are in constant motion within the company.
