blends made with HFCs and hydrocarbons can have GWPs of more than 150.
UNEP is assisting the Kingdom to adopt new, more energy efficient blowing agent
technology which will help the nation meet its energy targets.
2], so called dry ice, is of interest as blowing agent
for polymer foams as the dosage in form of pellets allows introducing the blowing agent
over the material feed.
Honeywell said that Solstice LBA is a next-generation blowing agent
with a global warming potential of 1, significantly lower than previous-generation hydrofluorocarbon blowing agents
The new blowing agent
being developed is a non-flammable liquid that will assist customers in reducing the overall environmental impact of foam.
In 2006, Honeywell introduced its low-GWP portfolio, which is based on hydrofluoroolefin (HFO) technology, and last year it commercialised HFO-1234ze, a low-GWP gaseous blowing agent
for one-component foam in Europe.
has developed a technique that uses pure carbon dioxide, instead of CFCs and HCFCs, as the propellant, or blowing agent
, in the manufacture of polystyrene foam.
As manufacturers of home refrigerators prepare to select the next-generation blowing agent
to use with polyurethane foam after 2002, Bayer Corporation, Pittsburgh, PA, is providing original research on blowing agent
options, and is offering the resources of its state-of-the-art Appliance Lab.
During production, a blowing agent
blows gas into the polystyrene.
It is a result of diffusion of the blowing agent
, typically pentane, out of the cells and its replacement in the cells by air.
Dabco PM301 catalyst - a patented, non-emissive, organic modifier that can promote HFO blowing agent
solubility in SPF applications.
Also, since physical blowing agent
is injected into the primary extruder, the screw in the extruder plays an important role in dispersing the blowing agent
into extremely fine droplets.
