Colortherm® pigments are easy to use. Because they are ground into ultra-fine particles during production, they are available as a powder that is easily distributed in plastic. More specifically, this means that a content of 1 to 4 percent by weight in the plastic “blades of grass” creates a rich color. The pigments are also coated with a special protective layer, allowing them to be processed at temperatures of up to 260 degrees without losing their color intensity. In addition to Colortherm® Yellow pigments, which are used for artificial turf, LANXESS also offers reds, greens, browns and blacks that are available in up to 100 different shades. “The synthetically produced iron oxide pigments are completely safe for people and nature,” Stefano Bartolucci explains. In terms of mass, iron is the second most common element on earth and is the fourth most common one in the earth’s crust, accounting for around 5 percent. “However, in terms of coloring, our pigments are superior to their natural counterparts thanks to their purity,” Bartolucci says.
From seats to artificial track
Green, red, yellow, brown or black – thanks to their properties, LANXESS pigments can be used to color nearly all plastics. So it is no wonder that they are today used beyond artificial turf to color plastic products in the world of sports. Years on, LANXESS pigments still keep running tracks and seats in the stands at many stadiums looking colorful and bright, despite sun, rain, snow, ice and technical demands.
