Wacker Polymers recently marked the completion of the capacity expansion for vinyl-acetate-ethylene copolymer(VAE)dispersions and VAE dispersible polymer powders at its Nanjing site in China.With a new reactor for dispersions and a new spray dryer for dispersible polymer powders,the expansion more than doubles Wacker's production capacity in Nanjing,enabling it to meet growing customer demand for its high-quality binders,particularly from China's buoyant construction industry.Wacker invested around US$ 100 million in its integrated production site for the expansion measure.The VAE dispersions project was designed around an advanced dispersion-polymerisation process and a safety control system that meets high standards,making the entire process cutting-edge in this field.The new production line forVAE dispersible polymer powders adopts advanced spray-drying technology and features an advanced process control system(APC).The two new plants are the largest of their kind in the world.
