用途
使用
HFC 125s main application is as a high-pressure refrigerant. It has also found use as a total flooding fire-extinguishing agent.
一般的な説明
A nonflammable gas. Heavier than air. May asphyxiate by the displacement of air in confined spaces. Exposure of the container to prolonged heat or fire can cause Pentafluoroethane to rupture violently and rocket.
