Abstract: A polyvinyl chloride (PVC) foamed ceiling panel and a fabrication method thereof are disclosed. The PVC foamed ceiling panel is made of a PVC resin powder, a filler, a foaming regulator, a composite foaming agent, a calcium-zinc stabilizer, a lubricant, a pigment, a weather resistance modifier, a smoke suppressant, and a flame retardant. The PVC foamed ceiling panel has the advantages of heat resistance, matting, smoke suppression, flame retardancy, environmental friendliness, light weight, small thickness, safety, long-term action, long service life, wide use range, and the like, and can be used for suspended ceilings in residential buildings, office buildings, exhibition halls, conference halls, and the like and for various decorations. The fabrication method of the PVC foamed ceiling panel has the advantages of low cost, high performance, scientific rationality, and simple and easy operation.
