Systematic evaluation of 1,2-dichloropropane emissions from do-it-yourself spray foam insulation products

Assessment of the Performance of Hydrofluoroolefins, Hydrochlorofluoroolefins, and Halogen-Free Foam Blowing Agents in Cellular Plastic Foams

“…Table 5 summarizes the characteristics of hydrocarbons that prevent their use in High-Pressure spray foam applications. In the process of SPF application, a fraction of the blowing agent is inevitably released into the atmosphere [4,6,18,19]. Consequently, the flammability of the blowing agent itself emerges as a pivotal concern for SPF applications, and different strategies have been explored to mitigate potential ignition sources.…”

“…Hydrocarbon blowing agents such as n-pentane, isopentane, and cyclopentane are commonly used for other applications such as foam board, integral skin, appliances, panels, and others. In the case of SPF applications, some portion of the blowing agent is emitted into the atmosphere [4,6,18,19]. In the case of hydrocarbons, these emissions can cause explosive atmospheres, especially in poorly ventilated spaces.…”
