Plant Overview
BASF has successfully started its new hexamethylenediamine (HMD) plant in Chalampé, France. Construction began in 2022, and the facility now boosts BASF’s annual HMD production capacity to 260,000 metric tons. This development is a key part of BASF’s strategy to enhance its polyamide (PA) 6.6 business in Europe.
Strategic Expansion
Alongside the new HMD plant, BASF is in the final stages of expanding its PA 6.6 production in Freiburg, Germany. This expansion aims to position BASF as a leading supplier of HMD and a preferred partner for PA 6.6 in Europe. The integration of the plant with the main raw material, adiponitrile (ADN), in the Alsace region provides an efficient setup for production and supply.
Applications and Uses
HMD is a crucial precursor in producing high-quality PA 6.6 polymers and coatings raw materials. These products are widely used in the automotive industry and in manufacturing high-quality fibers. The Chalampé site also hosts a state-of-the-art research and development laboratory dedicated to PA 6.6 research, further supporting BASF’s production capabilities.
