Blowing or foaming agents fall into two general classes—physical and chemical. Various gasses and volatile liquids are used as physical blowing agents. Chemical foaming agents (CFAs) can be organic or inorganic compounds that release gasses upon thermal decomposition. CFAs are typically used to obtain medium- to high-density foams, and are often used in conjunction with physical blowing ...

A blowing agent is a substance which is capable of producing a cellular structure via a foaming process in a variety of materials that undergo hardening or phase transition, such as polymers, plastics, and metals.They are typically applied when the blown material is in a liquid stage.The cellular structure in a matrix reduces density, increasing thermal and acoustic insulation, while ...

09.02.2017· If spray foam manufacturers ever found a way to use CO2 (carbon dioxide) as a blowing agent, then they would be able to brag that their blowing agent has a global warming potential of 1. Even better is a blowing agent with a global warming potential of zero. As far as I know, some spray foams offered by Icynene use water as the blowing agent ...
Chat Online01.06.2019· 2.2.2. Chemical Blowing Agent . Chemical blowing agents are classified into two categories, i.e., inorganic and organic foaming agents. The blowing agents can also be separated into two types, thermal decomposition, and reaction blowing agents. The inorganic blowing agent is mainly used in synthetic rubber, natural rubber, and rubber foam products.

Chat OnlineThe gas that is used in the foam is termed a blowing agent, and can be either chemical or physical. Chemical blowing agents are chemicals that take part in a reaction or decompose, giving off chemicals in the process. Physical blowing agents are gases that do not react chemically in the foaming process and are therefore inert to the polymer forming the matrix. Polymer foams are …

Polymer foams are commonly made by either physical [1,2] or chemical [, , ] blowing agents. Although the physical foaming method produces polymer foams with higher expansion ratio than chemical foaming methods [ 6 ], conventional extruders can be used with less sophisticated equipment with the use of chemical blowing agent (CBA) [ 7 ].
