Abstract: A structure of a demister hose for vehicles includes a demister outlet formed in a crash pad, a seal pad provided along an outer circumferential edge of the demister outlet and a restraint that guides defrost air toward the demister outlet and that prevents the seal pad from protruding toward the interior of the demister hose.

Abstract: Disclosed herein is a polypropylene composite composition. The polypropylene composite composition comprises 50 to 80% by weight of polypropylene, 6 to 30% by weight of talc, 10 to 30% by weight of a rubber, 3 to 15% by weight of glass bubbles, and 0.5 to 7% by weight of maleic anhydride polypropylene (MAH-PP). According to the composition, the compatibility between the glass bubbles and the polypropylene can be improved, thus enabling effective use of the glass bubbles. Therefore, when the composition is used to produce automotive components, such as automotive interior components, the fuel efficiency of automobiles can be improved due to weight reduction effects of polypropylene composites. In addition, since the composition uses colorless and odorless glass bubbles, it can remove an unpleasant smell generated from conventional interior components using talc and is thus environmentally friendly.

Abstract: Disclosed herein is an apparatus for processing a polypropylene compound containing glass bubbles. The processing apparatus includes an extruder receiving a screw therein, a first hopper mounted on an outer peripheral surface of the extruder at a position corresponding to a beginning portion of the screw and used to introduce the polypropylene compound, which is a main material, into the extruder, and a second hopper mounted on the outer peripheral surface of the extruder at a position spaced apart from the first hopper by a predetermined distance and used to introduce glass bubbles into the extruder, so as to allow the glass bubbles to be mixed with the polypropylene compound that is being transferred by the screw. The processing apparatus has the effect of preventing damage to glass bubbles by minimizing a passage distance of the glass bubble along the screw of the extruder, thereby achieving a reduced weight and improved physical properties of a molded article to be discharged from the extruder.
