Dominance of Hydrofluorocarbons Among Foam Blowing Agents Due to Improved Insulation and Low Flammab

The selection of the foam blowing agents facilitates a closed-cell structure that reduces heat transfer partly led by the foam blowing agent properties retained within the foam for lifelong use of the foam. The blowing agent can be liquid or gas form dissolved in the foam precursors that also expands after being injected or sprayed, beginning the foaming reaction. The foam blowing agent ,and foam matrix are bonded with the impermeable metal facings ,and are chosen to reduce migration of the blowing foam agent to further increase the thermal conductivity.
In addition, the foam blowing agent with low thermal conductivity enhances foam insulation properties, by facilitating thinner profiles or improved insulation performance. Foam blowing agents are used in a wide variety of buildings, refrigerators, furniture, automobiles, packaging, and, others.
