Intensive mixing is required to achieve a homogeneous polymer-gas-solution, whereas high pressures are essential to keep the blowing agent
in solution [3, 4], Mixing of the polymer-gas mixture is achieved by screws with special mixing elements , To compensate for the drop in viscosity caused by the blowing agent
, overlength single-screw extruders, tandem-lines, or additional melt-cooling-units are applied to cool the melt and bring the viscosity up to the process window for foaming .

Named Winner of 2015 Polyurethane Innovation Award by Center for the Polyurethanes Industry
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.
The combination of the blowing agent
and the hot-melt com pound, at recommended high contents, makes it possible to very greatly reduce an expansion ratio and therefore a thickness of the rubber layer once the pneumatic tire is vulcanized, without affecting noise absorption properties provided by the blowing agent

a leading Japanese manufacturer of industrial products, has adopted Honeywell s next-generation SolsticeA Liquid Blowing Agent
(LBA) for use in its line of spray polyurethane foam (SPF) building insulation sold under the trade name Achilles Airlon FR-FO.
New Jersey USA-based avionics technology and manufacturing firm Honeywell (NYSE: HON) said that its Solstice Liquid Blowing Agent
has been selected as a component in the spray foam roofing system for the Cleveland Airport System including multiple terminal and maintenance buildings at Cleveland-Hopkins International and Burke Lakefront airports.
Extrusion Dies Industries, LLC (EDI), of Chippewa Falls, Wisconsin, USA, has announced a new die system for extruded polystyrene (XPS) foam board that "dramatically reduces downtime for product changeovers, enabling manufacturers to offset much of the loss in productivity caused by switching to a non-ozone-depleting blowing agent
Honeywell is developing a new low-global-warming-potential blowing agent
for energy-efficient polyurethane foam insulation.
After a historical perspective on foam development, chapters cover blowing agent
evolution and its role in foam extrusion and injection molding, give examples of sustainable foam development, and describe novel foam products such as nanocomposite foam and energy security foam.
The Honeywell material, which should be available in sample quantities later this year, is a non-flammable liquid that the company says will offer performance benefits comparable to those of other fluorocarbons, but with a low global-warming potential, in addition, the blowing agent
will have an atmospheric lifetime of just a few days.
Honeywell today said it is developing a new blowing agent
for energy-efficient polyurethane foam insulation with lowered greenhouse gas emissions.
