The present invention relates to a non-coating thermoplastic resin composition, a method for manufacturing a molded article by using the same, and a molded article manufactured by the same. More specifically, the present invention is characterized by providing the thermoplastic resin composition which contains polycarbonate, polysiloxane-polycarbonate copolymer, polyester, master-batched carbon black, and additives in specific contents and the molded article, which has excellent chemical resistance, mechanical properties, light resistance, hydrolysis resistance, and low glossiness, manufactured by using the same.

Low gloss non-coating thermoplastic resin composition, method for manufacturing molded article by using the same, and molded article manufactured through the same

Disclosed herein are a polyamide composition and a molded article made of the same with improved mechanical strength and reduced weight. The molded article may include the polyamide composition that includes high flowable polyamide and polyphthalamide and a small-diameter fiber, thereby resulting in an improvement in mechanical strength while achieving excellent surface properties and high weight reduction.

Polyamide composition and molded article made of the same with improved mechanical strength and reduced weight

Disclosed is a thermoplastic elastomer composition having a superior low-temperature flexibility is provided. The thermoplastic elastomer composition may include an amount of about 10 to 15 wt % of a polypropylene-ethylene copolymer; an amount of about 70 to 85 wt % of a thermoplastic elastomer including an olefin-based thermoplastic elastomer and a styrene-based thermoplastic elastomer; an amount of about 5 to 10 wt % of a softener; an amount of about 3 to 5 wt % of a reinforcing agent; and an amount of about 1 wt % or less but greater than 0 wt % of a UV stabilizer based on the total weight of the thermoplastic elastomer composition.

Composition of thermoplastic elastomer

Disclosed is a coating material for a coating layer of an injection mold, the coating material including 100 parts by weight of a resin composition and about 30 to 40 parts by weight of a curing agent. The resin composition includes an amount of about 40 to 50 wt % of a first acrylic resin, an amount of about 5 to 15 wt % of a second acrylic resin having a weight average molecular weight less than a weight average molecular weight of the first acrylic resin, an amount of about 10 to 15 wt % of a carbon component, an amount of about 0.5 to 2 wt % of a matting agent, an amount of about 0.1 to 0.3 wt % of a catalyst and an amount of about 20 to 35 wt % of a solvent, all the wt % are based on the total weight of the resin composition.

Coating material for coating layer of injection mold and method of manufacturing coating layer of injection mold

Disclosed is a polypropylene resin composition for an uncoated crash pad. The composition may include an amount of about 50 to 80 wt % of a polypropylene resin having a Polydispersity Index (PI) of about 4.5 to 6.5, a weight average molecular weight of about 200,000 to 350,000 g/mol, and an isotactic peptide fraction of about 96% or greater as measured by a C-NMR method, an amount of about 1 to 30 wt % of rubber having a melt index of about 1 to 6 g/10 min (230&#xb0; C., 2.16 Kg), an amount of about 11 to 30 wt % of an inorganic filler composed of a mixture of an amount of about 10 to 20 wt % of talc and an amount of about 1 to 10 wt % of whisker, and an amount of about 1 to 5 wt % of an anti-scratch agent, all the wt % are based on the total weight of the polypropylene resin composition.

Polypropylene resin composition for uncoated crash pad

A polypropylene resin composition may include an amount of 40 to 60 wt % of a polypropylene resin, an amount of 1 to 10 wt % of a polyethylene resin, an amount of 10 to 20 wt % of an olefin elastomer, and an amount of 1 to 20 wt % of a reinforcing material wherein all the wt % are based on the total weight of the polypropylene resin composition. Accordingly, a high gloss may be obtained without a coating process and moldability of the polypropylene resin may be obtained. Further provided is a molded article of an interior material or an exterior material of a vehicle manufactured by using the polypropylene resin composition.

Polypropylene resin composition and article prepared therefrom

A polyolefin composite composition is used in an automotive air duct. The polyolefin composite composition is useful as an automotive air duct component material due to excellent mechanical property, heat resistance, and foaming property as a composition in which a polyethylene resin and a long chain branched polypropylene resin having low crystallization of 45% or less are included as a base resin.
