LANXESS Inorganic Pigments Drive Sustainable Development

Specialty Chemical Company LANXESS with its Inorganic Pigments business unit is participating in Chinaplas 2011 in Guangzhou, showcasing itself as a sustainable partner with premium products and innovative solutions.

LANXESS Inorganic Pigments is featuring its line of tailor-made inorganic pigments for plastics coloring, including high-performance Iron Oxide and Chrome Oxide Green products of the industry leading Bayferrox® and Colortherm® pigment ranges. The extraordinarily lightfast, weather-stable and chemical resistant products are distinguished by their outstanding quality as well as their easy and environmentally compatible processing.

“We are committed to offer customers added value through cutting-edge technology, ecologically efficient production processes, and innovative products that contribute to sustainable development,” says Dr. Wolfgang Oehlert, Vice President for the Inorganic Pigments business Unit in Asia Pacific.
A decisive advantage of LANXESS’ high-performance pigments lies with their tight tolerances in color shade and tinting strength. This makes color reproduction when formulating masterbatches or paints and coatings faster, easier and more reliable; shading work is reduced to a minimum. In addition, LANXESS inorganic pigments are characterized by an unmatched dispersibility, achieved through micronization, a very intensive form of grinding that results in a significant reduction in the proportion of pigment aggregates in the product.

The unique reds of IPG’s Bayferrox and Colortherm Red100 series cover a very broad range of hues, extending from a yellowish cast to a distinctly bluish shade. The special quality properties achieved in the manufacture of these high-performance pigments are related to the unigue Laux process. This process is used for 85 years by LANXESS in the world’s largest production facility for inorganic pigments at the company’s site in Krefeld-Uerdingen. The process is exemplary in its consistent use of the reaction heat generated during synthesis. This heat is used for the production of steam and hot water for further process steps, resulting in virtually no additional requirement for external heat. Thus, the energy efficency of the Laux process is superior to all other processes for the manufacturing of iron oxide pigments.

This special process produces pigments with excellent, unique heat resistance and protects them from changes in the hue even when they are subjected to intense milling, grinding or dispersion, making Bayferrox and Colortherm pigments the first choice in all temperature demanding applications, including the plastics industry. The world class quality consistency of the Bayferrox and Colortherm grades provide a reliable basis for all customers, allowing for more efficient processing and for high quality products driving the customers’ success.
Alongside the red shades LANXESS is also showcasing high-performance iron oxide yellow pigments at the Chinaplas. The unique bright yellow products Colortherm Yellow 10 and 20 have been developed specifically for high-temperature demanding applications and show unmatched color stability during the plastics extrusion processes thanks to innovative LANXESS’ technology.

“Chinese markets, especially the high end application sectors in the plastics industry, are very important for LANXESS Inorganic Pigments’ sustainable growth in the Asia-Pacific region,” says Dr. Oehlert. “We’ve seen a growing demand for our high-performance pigments here, and we are confident that the trend will continue as the growth of Chinese economy will further increase the needs for our premium pigments that can meet even the most challenging high-end applications.”

LANXESS Inorganic pigments are not only proven performers for plastics coloring, they also have a decades-long record of performance for the coloration of paints and coatings, the coloration of concrete, paper, and for use as specialty pigments for toners and other applications. Its international production network has total synthesis capacity of more than 350,000 metric tons p.a. In China, LANXESS’ Jinshan site produces high quality yellow and black Bayferrox® iron oxides at the capacity of 38,000 metric tons a year.

The Inorganic Pigments business unit belongs to the Performance Chemicals segment, which achieved total sales in fiscal 2010 of EUR 1.98 billion.

LANXESS is a leading specialty chemicals company with sales of EUR 7.1 billion in 2010 and currently around 15,500 employees in 30 countries. The company is at present represented at 46 production sites worldwide. The core business of LANXESS is the development, manufacturing and marketing of plastics, rubber, intermediates and specialty chemicals.
