"We continue to experience unprecedented escalations in raw materials, energy, and transportation costs," said Kristi Wolohan, Marketing Manager for Dow's High-Temperature Thermal Fluids products. " The devastating effects of the recent hurricanes have put additional pressure on critical petrochemical feedstocks and energy prices. In addition, the disruption of the transportation infrastructure in the Gulf Coast has further tightened supply of raw materials utilized to manufacture our products. We must implement these increases in order offset the rising costs to manufacture and transport our products and remain a strong and reliable supplier".
