Melbourne, Victoria — Huntsman Polyurethanes (Australia) is supplying a new system to water heater manufacturer Rheem New Zealand.
The system was developed to use Honeywell’s Solstice Liquid Blowing Agent (LBA) technology is hydrofluoroolefin (HFO)-based with low global warming potential. It is non-flammable and VOC exempt, according to Huntsman.
Research started in mid-2014 in preparation for Rheem’s phasing-out of HCFC (hydrochlorofluorocarbon) 141b, the blowing agent it had been using.
“We ran our first production trial just prior to the full change over to cover any issues that may arise,” Stephen Grindell, senior technical services officer for insulation at Huntsman told UTECH-polyurethane.com. “The conversion to Solstice went very smoothly.”
Refigerator makers Midea, Whirlpool and Italian firm Afinox now use Honeywell’s Solstice LBA, as previously reported at UTECH-polyurethane.com.
By the end of 2015 New Zealand will outlaw the import of HCFCs, according to Huntsman.
Now Rheem NZ is manufacturing all of its water heaters with insulation that employs an HFO-based blowing agent.
