Synthetic polymer-propellant compositions forming cold foamed structures having a temperature at least 30° C. below ambient temperature and containing open and/or closed cells

摘要: Synthetic polymer-propellant compositions are provided that capable of forming foamed structures having a temperature at least 30° C. below ambient and containing open and/or closed cells, which may optionally contain material is deposited in the pores walls structure as formed, comprising: (a) film-forming synthetic polymer an amount within range from about 2% to 30% by weight composition; (b) one liquefied propellant boiling -10° C; (c) total being 50% 90% heat vaporization 55 calories per gram; dissolving presence co-solvent soluble solutions temperature; (d) nonsolvent solution but insoluble 1% 85% composition upon volatilization pressure cells temperature.
