Ashland said it is responding to strong demand for Plasdone polyvinyl pyrrolidone (PVP) by adding new low-viscosity, pharmaceutical-grade PVP capacity at its manufacturing facility in Calvert City, Ky. The company said the new capacity will further strengthen its position in the market and will enable the company to continue supporting the growing needs of its pharmaceutical customers. The additional capacity is currently being validated for pharmaceutical-grade PVP production and will be available for sale to Ashland's pharmaceutical customers in March 2012.
