Effective November 1, 2014, or as contracts allow, Cabot Corporation will increase prices, up to 5 percent for black masterbatches and conductive compounds and concentrates. This price increase is required due to escalating costs of operations and regulatory compliance, as well as increased costs of carbon black and other key raw materials. The increase is necessary to ensure Cabot remains a reliable, long-term supplier of high-quality black masterbatches and specialty compounds, and ensures continued investment in new products dedicated to the plastics industry.
