Cabot Corporation Increases Prices for Specialty Compounds Globally

September 1, 2017

BOSTON – Effective October 1, 2017, or as contracts allow, Cabot Corporation will increase prices, up to 5 percent globally, for its PLASBLAK® masterbatches as well as its CABELEC® conductive compounds and concentrates. This price increase is required to offset rising raw material, transportation, and operating costs, as well as costs associated with investments in new capacity, supply reliability and regulatory compliance at its specialty compounds manufacturing facilities.

The increase is necessary to ensure Cabot remains a reliable, long-term supplier of high quality products and services, and to help ensure continued investment in its current assets as well as further expansions, product innovation and application development to support customers.
