What is the Flash Point of ETHAFOAM™ products?
The flash point is defined as “the lowest temperature at which a material will give off enough flammable vapor at or near its surface such that, in an intimate mixture with air and a spark or flame, it ignites.” (from Dangerous Properties of Industrial Materials, 4th Edition, N. Irving Sax, 1975). For ETHAFOAM products, the flash point is far beyond the melting point of the polyolefin polymers used to make the foams and is only reached when the foam has been heated considerably beyond the point at which it melts into a pool of liquid polymer. Thus flash point generally is not a concern under normal use and storage conditions. Flash points for ETHAFOAM products are above 600°F / 315°C or so, depending on the particular polymer used.
