Abstract: A polyamide 6,6 resin composition having improved toughness, abrasion resistance and frictional resistance is provided herein. The polyamide 6,6 resin composition comprises a graft copolymer of polyethylene and maleic anhydride, layered nanoclay, and a nucleating agent with a predetermined composition ratio in a base resin of polyamide 6,6 having ultra high viscosity. The polyamide 6,6 resin composition has properties of tensile strength (ISO527) of 83 Mpa or greater, elongation at break (ISO527) of 30% or greater, a kinematic friction coefficient of steel to metal measured by a ring-on-ring friction and abrasion tester of 0.30 or less, and a specific abrasion amount of 0.020 mm3/Kgf·km or less. The resin composition is useful as a worm gear for a motor-driven power steering device.

Abstract: A structure of a soundproof cover for an engine room is mounted on a body frame at a rear side of the engine room in which an engine is mounted. The structure may include two or more piece members that are detachably coupled to each other and collectively form the soundproof cover in a panel shape. The soundproof cover is to be mounted on the body frame so that one side surface of the soundproof cover is directed toward the engine and the other side surface of the soundproof cover is directed toward an interior of a vehicle.

Abstract: A polypropylene resin composition includes 1 to 30 wt % of homopolypropylene having a melt index of 2 to 6 g/10 min at 230° C. and 2.16 kg, and an isotacticity index of 97% or more, 1 to 40 wt % of homopolypropylene having a melt index of 16 to 22 g/10 min at 230° C. and 2.16 kg, and an isotacticity index of 96% or more, and 20 to 40 wt % of a glass fiber having an excellent rigidity supplementation effect as an inorganic filler for improving heat resistance, mechanical properties, and 1 to 10 wt % of denatured polypropylene as a compatibilizer maximizes compatibility of the polypropylene resin and the glass fiber, based on a total weight of the composition. The composition has excellent rigidity, short-term heat resistance, long-term heat resistance, and fusion strength, at a reduced weight and production cost.

Abstract: Disclosed is a polyamide resin composition for sound insulation, which includes a polyamide 66 or polyamide 6 resin, a glass fiber for improving mechanical and heat resistance properties of the composition, and barium sulfate for improving a sound insulation property of the composition. The polyamide resin composition can further include one or more of an antioxidant for preventing deterioration of the composition, a heat resistant stabilizer for improving heat resistance, and a lubricant for reducing friction to improve moldability. The polyamide resin composition thus has excellent mechanical properties, heat resistance, noise and vibration insulation performance, and can further be injection molded to thereby provide weight reduction and allow for the formation of complicated shapes.
