A recently granted patent (Publication Number: US11884814B2) discloses a resin composition designed for flame retardancy and improved mechanical properties. The composition includes hollow particles made of an organic polymer, epoxy resin, curing agents, silica, and phosphorus type flame retardants. The hollow particles have an average diameter ranging from 0.2 µm to 8 µm and are present in a specific mass percentage within the composition. The phosphorus type flame retardant contributes to the fire-resistant properties of the resin.

Furthermore, the patent claims cover variations of the resin composition, including the type of hollow particles used, their porosity, and the addition of elastomers to enhance flexibility. The cured product of this resin composition can be used in various applications such as laminates, resin sheets, printed wiring boards, and semiconductor devices. The composition's specific components and their proportions aim to provide a balance between flame retardancy, mechanical strength, and processability, making it suitable for a wide range of industrial uses.
