Study on non-flammable insulation used no freon and the results of evaluation

Abstract

We were evaluated to insulation properties and flammability on nonflammable thermal insulations that was able to construct on site and used no hydro-fluorocarbon. On the results of evaluation of insulation properties the nonflammable thermal insulations were more inferior to the foaming thermal insulations with carbon dioxide gas. In flammability, the foaming thermal insulations were burned easily to the nonflammable thermal insulations. The nonflammable thermal insulations were more safety materials than hard urethane forms on site.
