Influence of temperature on styrene emission from a vinyl ester resin thermoset composite material

► Styrene emissions from finished thermoset composite materials have not been previously published. ► Styrene emissions from composite materials are characterized here over a temperature range. ► Styrene emitted mass and emission factor increase nearly linearly with increasing temperature. ► Published styrene emission factors vary with material and temperature. ► Mass transfer models to predict emissions require material and temperature inputs.
