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.
