Abstract:	Polyether polyol, isocyanate, and a flame retardant (10 wt%), zeolite (0 wt%, 1 wt%, 3 wt%, 5 wt%, 7 wt%, and 9 wt%) are used to form the rigid polyurethane (PU) foam, while a nylon nonwoven fabrics (400 g/m2) and a polyester aluminum foil are combined to serve as the panel. The rigid PU foam and the panel are combined to form the rigid foam composites. The cell structure, compressive stress, combustion resistance, thermal stability, thermal conductivity, sound absorption, and electromagnetic shielding effectiveness (EMSE) of the rigid foam composites are evaluated, examining the effects of using flame retardant agent and zeolite. When the zeolite is 5 wt%, the rigid foam composites have an optimal density of 0.172 g/cm3, an average cell size of 0.2131 mm, a maximum compressive stress of 460.03Kpa, an optimal LOI of 28, and optimal EMSE of 40 dB, and the maximum thermal stability, thermal insulation, and sound absorption.
