Fluoroiodocarbon blends as CFC and halon replacements
First Claim
1. A method of using a foam blowing agent comprising the steps of:
- a) injecting a foam blowing agent into a monomer, where the foam blowing agent is a fluoroiodocarbon having the general formula Ca Hb Brc Cld Fe If Ng Oh, wherein a is between and including 1 and 8;
b is between and including 0 and 2;
c, d, g, and h are each between and including 0 and 1;
e is between and including 1 and 17, and f is between and including 1 and 2;
b) allowing the monomer to polymerize;
c) allowing the said foam blowing agent to substantially vaporize; and
d) allowing the cell walls to harden.

Abstract
A new set of effective, environmentally safe, nonflammable, low-toxicity refrigerants, solvents, foam blowing agents, propellants, and firefighting agents is disclosed. The agents are clean, electrically nonconductive, and have short atmospheric lifetimes, zero ozone-depletion potential, and low global warming potentials. The agents comprise at least one fluoroiodocarbon agent satisfying the general formula Ca Hb Brc Cld Fe If Ng Oh, wherein a is between and including 1 and 8; b is between and including 0 and 2; c, d, g, and h are each between and including 0 and 1; e is between and including 1 and 18; and f is between and including 1 and 2, either neat or mixed with additives selected from the group consisting of: alcohols, esters, ethers, fluoroethers, hydrocarbons, hydrofluorocarbons, and perfluorocarbons.
