	Protein foaming agent GreenFroth for light weight cellular concrete (foamed concrete)
		However, it is obvious that protein foaming agents are considerably better in the production of foam concrete than synthetic foaming agents because the main qualities of the protein foaming agents include the possibility to produce far firmer foam concrete of low densities.
		Moreover, the foaming agent which is based on organic vegetable raw materials has an increased ratio and a higher resistance of foam in comparison with other imported foaming agents and synthetic ones.
		Consequently now it is possible to reduce the consumption of the foaming agent on each cubic meter of foam concrete approximately to 45 % that adds to the quality and the strength of the produced foam concrete.

	Production of encapsulated chemical foaming concentrates - Patent 5611962
		Foaming of thermoplastics in the majority of applications is now accomplished with exothermic foaming agents, usually azo compounds, which when admixed with the desired thermoplastic polymer in an extruder or molding machine are heated above their decomposition temperatures, and produces nitrogen which forms the cell structure in the molded or extruded part.
		In contrast, pellets of foaming agents now produced use lower melting materials, often waxes, to reduce reaction and gas release or alternately the pellets are foamed or even collapsed showing evidence of reaction of the foaming agent during the compounding of the foaming agents (these pellets increasing in size before collapse).
		The chemical foaming agents are compounded with the resin carrier in the extruder as the mixture move from the side feeder 14 or hopper 16 to a die 20.

	Continuous extrusion of microcellular polycarbonate
		One prerequisite for microcellular foaming was believed to consist in a concentration of the blowing agent close to its limit of solubility as that defined under the actual processing conditions of pressure and temperature.
		Foaming agent concentration, processing temperatures and pressures, and influence of solubility and diffusivity on the nucleation mechanism are some of the key topics explored in this study.
		The total volume of the cells, and hence, the reciprocal of the foam density, are proportional to the molar quantity of foaming agent dissolved in the polymer.

		An antifoaming agent is a food ingredient intended to curb effusion or effervescence in preparation or serving.
		Antifoaming agents are included in a variety of foods such as Diet Pepsi, Diet Coke, Sprite, and chicken nuggets in the form of polydimethylsiloxane (a type of silicone).
		Antifoaming agents are also used medicinally to relieve bloating, because they cause small bubbles to coalesce into large bubbles, which are passed more easily.

	Bergen International: Extrusion Tips
		Foamazol™ chemical foaming agent, the foaming agent system developed by Bergen International for extrusion, is formulated in a way that, when used properly, ensures complete decomposition and a very consistent and fine foam structure, within a well-defined temperature range.
		As the foaming agent masterbatch melts in an early stage and reaches the decomposition temperature earlier, the resulting gas will dissolve the melt, due to the high pressures present at the beginning, and can be very well distributed in a short period of time.
		In this case the temperature of the feeding zone should be adjusted to a lower temperature, to prevent the premature decomposition of the foaming agent.
