foaming agent

Food industry
A substance added to liquid foods that facilitates the formation of foam or bubbles in drinks (e.g., instant chocolate milk).

Foaming agents
• Surfactants—e.g., sodium laureth sulfate, a detergent which reduces surface tension, making it easier to convert a liquid to foam and/or increases its colloidal stability by reducing the coalescence of bubbles; these are found in soaps, shampoos and toothpastes.
• Blowing agents, which provide the gas for the foam either because they are gases at a certain temperature (e.g., CO2, CFC), or because they generate gases due to a chemical reaction (e.g., baking powder, isocyanates).

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 [5], 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 [6].

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.

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.
