Abstract: 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.

Abstract: A continuous process for making a pressure-sensitive adhesive is disclosed. A mixture comprising natural rubber having a Mooney viscosity of 85 to 100, a tackifier, a filler, and 0.1 to 5 wt. % of an added C12-C24 fatty acid based on the amount of mixture is masticated in a first section of a single- or twin-screw extruder. Mastication of the mixture continues in at least one subsequent extruder section in the presence of additional tackifier. The product is a homogeneous, reduced-viscosity pressure-sensitive adhesive. The minor proportion of added C12-C24 fatty acid aids mastication of the rubber and enables high throughput without addition of peptizers. Duct tapes made from the adhesives display improved adhesion to steel, better adhesion bond strength, and enhanced seven-day clean removability from even difficult substrates such as marble or ceramic tile.
