The additives business unit of Clariant has increased the price of its wax portfolio as a result of higher costs for major raw materials, transportation and energy by five to 15 percent. Clariant's waxes are used mainly in plastics, coatings and inks, as well as in adhesives and polishes. “The current market environment, in combination with continued cost developments, leaves Clariant no other alternative but to increase prices for our customers," said Bernhard Ehrenreich, head of Clariant’s waxes business line. The price adjustments will take effect as of January 15, 2011.
