Polyole

• Polyols are the largest group of PUR starting materials. The widerange of properties of the resulting PUR is largely determined bythe chemical composition and molecular mass of the polyols.

• The largest group of polyols used for PUR is the group ofpolyethers.

Dow Polyurethanes Successfully CompletesTesting Phase for Natural Oil Polyols

Confirms Plans for Market Development Scale Production in2007

MIDLAND, Mich. — (September 25, 2006) — Dow Polyurethanes, a business unit of

The Dow Chemical Company, announced today that it has successfully completed the

lab and pilot-plant testing phases for development of natural oil polyols (NOPs) for

urethane formulations. Dow will begin sampling with a select group of customers

immediately, and begin market development scale production of the next-generation

polyols in 2007.
