The authors describe a synthesis method for a series of pulverized expandable graphite (pEG)/melamine-formaldehyde (MF) resin core-shell structure particles. The particles are also added into rigid polyurethane foams (RPUF) to characterize the flame-retardant, mechanical, and thermal insulation properties of the RPUF/pEG-MF composites. It was found that the pEG/MF particles showed good flame-retardant performance in the composites by providing a physical barrier effect....
Preventing steel from losing its strength during fires is crucial for safe evacuation and effective fire fighting. One of the most common protective coatings applied to steel and other construction materials today is intumescent paint. In this study, researchers created a potential new protective coating using a curable silicone base and varying volume amounts of expandable graphite between 5-25%. The key characteristic of these coatings is that they swell to ...
