Covestro co-blown rigid foam helps refrigerators save energy, reduce CO2 emissions

Pittsburgh, September 29, 2015 — Today’s energy-efficient refrigerators that meet the U.S. Department of Energy’s current minimum efficiency standards use nearly half the energy compared with refrigerators made 20 years ago. Covestro is a market leader in supplying polyurethane systems to the appliance industry, providing OEMs the materials crucial to insulating refrigerators, freezers and water heaters to meet rigorous energy efficiency standards.

U.S. Environmental Protection Agency regulations set to eliminate the future use of hydrofluorocarbons (HFCs) as blowing agents in insulating foam will necessitate the use of blowing agents with a low global warming potential (GWP) beginning in 2020. To help appliance manufacturers meet these regulations, Covestro has achieved significant advancements on fourth generation blowing agent systems, hydrocarbon-based blowing agent systems and systems co-blown with fourth generation and hydrocarbon blowing agents.

The newest formulations are optimized to be co-blown with cyclopentane and halogenated olefin blowing agents, achieving foams with better insulating ability than would be achieved by simply adding an hydrochlorofluoroolefin (HCFO) or hydrofluoroolefin (HFO) blowing agent to a typical cyclopentane formulation. The foam’s better insulating ability is demonstrated especially well at the lower operating temperatures common to refrigerators and freezers.

Covestro researchers will share additional details about these new, optimized formulations during their presentation, “Optimization of Polyurethane Rigid Foams Co-Blown with Cyclopentane and Halogenated Olefin Blowing Agents” at 2:30 p.m. Monday, Oct. 5 during the 2015 Polyurethanes Technical Conference in Orlando, Florida. The paper is authored by Steven Schilling, senior principal scientist; Steve Aprahamian, principal scientist; and Mike Super, applications development manager, all of Covestro.

“Through our work, we are providing options to the appliance industry to help them meet increasing energy efficiency standards,” Schilling said. “We are also helping to give consumers a choice to reduce the amount of CO2 that is generated to power their appliances and save money on their electric bills, simply by choosing to buy one of the new, more energy-efficient appliances insulated with our raw materials.”
