GRAND RAPIDS, Mich. — Shares of several chemical companies fell Tuesday after industry leader Dow Chemical Co. announced its second set of wide-ranging price hikes in less than a month, again trying to offset record costs for energy and raw materials.

Midland-based Dow said it will raise the prices of its products by as much as 25 percent in July after implementing across-the-board price increases of up to 20 percent on June 1.

The company makes everything from the propylene glycols used in antifreeze, coolants, solvents, cosmetics and pharmaceuticals, to acrylic acid-based products used in detergents, wastewater-treatment and disposable diapers.

When Dow raises prices, the increase is felt across dozens of industries that buy its chemicals and plastics to manufacture products.
