Resin composite having excellent soundproofing and mechanical properties
Disclosed are a resin composite having excellent soundproofing and mechanical properties, and a molded product including the same. The resin composite may include a resin composition, porous particles and a reinforcing material, and the molded product including the same include no volatile organic compounds (VOCs). As consequence, displeasure caused by generation of the VOCs and exhaust of toxic gas during combustion may be reduced thereby being environmentally friendly. Further, the resin composite and the molded product including the same demonstrate sufficient mechanical strength and may thus be directly applied to a housing or the like of an apparatus which generates noise without introduction of any additional soundproofing material. For example, the resin composite and the molded product may include a specific content of the porous particles having pores having a specific size to secure an appropriate volume fraction and may thus efficiently and economically block noise transmission.
