The Dow Chemical Co., Midland, Mich., collaborated with Honeywell International, Inc., Morristown, N.J., to develop new polyurethane insulation system used in Dow foam insulationfreezers.

Honeywell’s Solstice Liquid Blowing Agent (LBA) is said to help the insulation lower global warming potential (GWP) by 99.9%. The polyurethane foam’s insulating properties are enabled by the blowing agent as it expands and is retained in the foam’s closed-cell structure, helping manufacturers comply with environmental and energy efficiency regulations.

The polyurethane material is designed to provide both improved mechanical and physical properties, including:

·         Optimal thermal conductivity to meet increasingly demanding energy standards.

·         Good flow and uniform density distribution of the foam.

·         A curing profile that allows for competitive de-mold times.

·         Excellent adhesion to a variety of substrates.

·         Excellent mechanical properties resulting in outstanding dimensional stability.

·         Extended shelf life of the fully formulated system with HFO.
