PHOENIX (ICIS)--TSE Industries has developed a system that allows polyurethanes (PUs) to be used in filament winding applications, a use that has previously been limited to vinyl esters and epoxy resins, executives for the company said on Wednesday.
The applications include pipes, tanks and pressure vessels that are used in water distribution, reverse osmosis systems and water heaters, said Curtis Reichel, director of research and development (R&D) for TSE Industries.
Reichel made his comments on the sidelines of the Polyurethanes Technical Conference, hosted by the Center for the Polyurethanes Industry (CPI).
The development could open polyurethanes a market that was estimated to be worth $4.2bn (€3.1bn) in 2007, said Mark de Souza, composites R&D manager for TSE Industries.
TSE's project was among the finalists for the Polyurethane Innovation Award at the CPI conference.
In the past, polyurethanes had not been used in filament winding applications because they have a tendency to foam in high humidity, Reichel said.
TSE was able to overcome that barrier.
Moreover, the resulting product has several advantages, de Souza said.
The polyurethanes product has no volatile organic compounds (VOCs) that can leach out, he said. Polyurethane resins cure in about an hour, compared with 8-24 hours for epoxy resins and 3-4 hours for vinyl esters.
When tanks made with the polyurethane material underwent strength tests, they performed significantly better than the other materials, de Souza said.
