The present invention provides a glass wool cutting device. The device includes a cutting section housing that has a cutting section chamber, a feed port that is connected to the cutting section chamber, and a discharge port that is connected to the cutting section chamber. A stationary knife is disposed on the cutting section housing to protrude into the cutting section chamber and a movable cutter that has a rotary support body is disposed in the cutting section chamber and a movable knife is supported on the rotary support body to apply a shearing force to the glass wool together with the stationary knife. Additionally, a cutter actuator provides a driving force to the rotary support body.

A polypropylene composite resin composition includes: 30 to 70% by weight of high crystalline block copolymer polypropylene, based on the total weight of the polypropylene composite resin composition; 10 to 20% by weight of a rubber elastomer, based on the total weight of the polypropylene composite resin composition; 10 to 18% by weight of a reinforcing material, based on the total weight of the polypropylene composite resin composition; 2 to 4% by weight of a mercaptosilane coupling agent, based on the total weight of the polypropylene composite resin composition; and 1 to 5% by weight of a slip agent, based on the total weight of the polypropylene composite resin composition.

Polypropylene composite resin composition having excellent scratch resistance and mechanical properties

A polypropylene composite resin composition and an automotive interior part molded using the polypropylene composite resin composition are provided herein. The polypropylene composite resin composition contains: (a) an easily injection moldable polypropylene polymer, (b) a thermoplastic elastomer for improving impact resistance, (c) a platy inorganic filler surface-treated with an organosilane having affinity for a phytoncide, (d) a phytoncide having deodorizing capability and aromaticity, (e) a processing oil preventing pyrolysis of the phytoncide, and (f) a surfactant for improving the compatibility between the base resin and the phytoncide at specific compositional ratios. The automotive interior part molded using the polypropylene composite resin composition disclosed herein provides a pleasant environment for drivers by removing the offensive odor from volatile organic compounds (VOCs), etc. and maintaining the intrinsic scent of the phytoncide for a long time.
