PHOENIX (ICIS)--Dow Chemical is targeting its Vorapel polyols for products that can be used to repair pipes, bridges and other infrastructure, executives with the company said on Monday.

Polyols are one of the main raw materials that are used to make polyurethanes. Depending on the feedstock, these polyurethanes can be flexible foams, rigid foams or elastomers among many others.

Vorapel is a polyether polyol that is used to make polyurethanes that are hydrophobic and resistant to chemicals, said William Koonce, research and development (R&D) development, polyurethanes, for Dow Chemical.

He made his comments on the sidelines of the Polyurethanes Technical Conference, hosted by the Center for the Polyurethanes Industry (CPI).

In addition, Vorapel has good durability, long shelf-life and low viscosity, Koonce said. That low viscosity will allow it to be incorporated into spray systems.

These and its hydrophobic properties make resulting elastomers ideal for products used to repair bridges and pipes, Koonce said.

Pipes, in particular, could lend themselves to Vorapel.

Chris Chrisafides, commercial director, North America, Dow Polyurethanes said Vorapel can help fix busted mains which cause serious loss of water in the cities.

"We think it will truly be a new material on the market," he said.

Dow expects Vorapel to replace other materials that are used as linings for tanks, Koonce said. Epoxy resins, for example, tend to be brittle.

By contrast, polyurethanes and polyureas are elastic, flexible and − with Vorapel − durable, Koonce said.

The technical conference runs through Wednesday.
