Foam Insulation Using Honeywell’s Ultra-Low Global-Warming-Potential Material Added To Japanese Industrial Standard

Honeywell’s Solstice® Liquid Blowing Agent helps building owners in Japan
meet targets for phasedown of higher-global-warming materials

TOKYO, Jan. 27, 2016 – Honeywell (NYSE: HON) announced today that the Japanese Industrial Standards Committee has added foam insulation material using Honeywell’s ultra-low global-warming-potential (GWP) blowing agent to the list of materials recognized by Japanese Industrial Standard (JIS), as providing building owners a new alternative to meeting targets for phasing down of higher-GWP materials.

The committee added a specific classification for spray-applied rigid polyurethane foam for thermal insulation (JIS A 9526:2015) for polyurethane foam using hydrofluoro-olefin (HFO) blowing agents. The foam is used to insulate residential buildings, among other applications. Honeywell’s Solstice LBA, which has a GWP of 1, is the leading HFO blowing agent used in foam insulation in Japan today.

“The addition of the HFO-based foam classification proves it can be used to meet stringent Japanese standards, providing business owners with the assurance that they are making the right choice for their business and the environment,” said Katsuyuki Takise, general manager for Honeywell’s Advanced Materials business in Japan.  “Solstice LBA is already commercially available, and we look forward to increasing the already wide adoption of this technology throughout Japan.”

Japan has moved in recent years to phase down the use of higher global-warming hydrofluorocarbon (HFC) blowing agents in spray foam insulation for buildings, with the goal of moving to foam insulation materials with a GWP of 100 or lower by 2020. The Japan Urethane Foam Association (JUFA) is urging phaseout of HFC blowing agents in spray foam insulation and supported the establishment of the new standard.

The new classes of 1H and 2H specifically designate spray foam systems using HFOs as follows:

jis20160128 Added to JIS A 9526:2015 :

Class Code Description
Class A, 1H NF1H Closed cell foam using HFO blowing agent, for applications require medium strength such as wall, and ceiling (indoor)
Class A, 2H NF2H Closed cell foam using HFO blowing agent, for applications require high strength such as refrigerated warehouse.

Solstice LBA, which is based on HFO technology, received a “Non-Flon” designation from Japan’s Ministry of the Economy, Trade and Industry (METI) in June 2015. It has an ultra-low global warming potential of 1, which is 99.9 percent lower than HFC blowing agents it replaces and equal to carbon dioxide. It is non-ozone-depleting and nonflammable. Solstice LBA has received U.S. EPA approval under the Significant New Alternatives Policy (SNAP) program as a suitable replacement for HFC blowing agents, such as HFC-245fa and HFC-365mfc. Solstice LBA is volatile organic compound (VOC)-exempt per U.S. EPA.

Recently Honeywell announced that closed-cell spray foam insulation using Solstice LBA has been adopted for more than 80 building projects nationwide. Solstice LBA’s thermal performance exceeds traditional water/CO2–based systems. The thermal conductivity of HFO-based foams of 1H and 2H classes are less than 0.26 W/(m・k) while water/CO2–based Class A-1 is less than 0.34 W/(m・k). Typically HFO-based foam can be 25 percent thinner to achieve the same or better performance of water/CO2–based systems.

Honeywell also offers Solstice Gas Blowing Agent (HFO-1234ze(E)), which replaces HFC-134a as a foam blowing agent in insulation for commercial  appliances and board insulation for homes and buildings.
