Flash point of polypropylene
WebThe flash point, autoignition temperature, and heat of combustion of Acetonitrile are listed in Table 2.1. The flash points of several Acetonitrile-Water mixtures have been determined. The results are shown in Figure 2.8. Vapor mixtures of Acetonitrile and air containing between 4.4 and 16 percent Acetonitrile at 25°C are potentially flammable. WebIt has a higher pour point and, unlike the lower molecular weight PPGs, is partially soluble in water at 25 °C. It loses its water solubility at higher temperatures. Like all polypropylene glycols, Polyglycol P-2000E is soluble in all proportions with any organic solids and liquids, the main exception being long chain aliphatic hydrocarbons.

Flammable liquids have a flash point of less than 100°F. Liquids with lower flash points ignite easier. Combustible liquids have a flashpoint at or above 100°F. The vapor burns, not the liquid itself.
