Lanxess has completed the US$5.6m expansion of its Macrolex dyes production plant at Chempark, Leverkusen, increasing capacity by around 25%.

"By expanding the plant, we are responding to the increased global demand for high-quality dyes in the plastics industry," said Lanxess Rhein Chemie business unit (RCH) head, Philipp Junge.

For his part, RCH Colourant Additives Business VP, Dominik Risse added: "With the expanded capacity, we can now continue to grow, especially in sensitive application areas such as high-quality plastics packaging."

The soluble organic dyes marketed under the Macrolex brand are mainly used to colour plastics products such as beverage bottles, electronic equipment, car tail lights and children's toys.

The portfolio of Lanxess's colourant additives business comprises a total of 150 products and, in addition to Macrolex dyes, other colourants for use in a wide range of applications, from LCD screens to colourants for writing instruments.
