A chemical resistant polymer composition for a center fascia includes a resin composition consisting of 10 to 20% by weight of a polyester copolymer containing a residue of a dicarboxylic acid component containing terephthalic acid and a residue of a diol component containing dianhydrohexitoll; 15 to 25% by weight of polytrimethyleneterephthalate; 10 to 20% by weight of one or more copolymers selected from the group consisting of an unsaturated nitrile-diene-based rubber-aromatic vinyl graft copolymer, an alkylmethacrylate-diene-based rubber-aromatic vinyl graft copolymer, and an alkylmethacrylate-silicone/alkylacrylate graft copolymer; and 50 to 65% by weight of polycarbonate based on the weight of the resin composition. The polymer composition further comprises 0.1 to 10 parts by weight of a phosphite-based antioxidant, based on 100 parts by weight of the resin composition.

Chemical resistant polymer composition for a center fascia

The present invention relates to a polypropylene-based resin composition including: (A) a polypropylene resin in an amount of about 40 to 90 wt %, (B) a metal hydroxide in an amount of about 1 to about 25 wt %, (C) an inorganic filler in an amount of about 5 to about 15 wt %, and (D) a polyolefin-based elastomer in an amount of about 0 to about 20 wt %, and a method for manufacturing the polypropylene-based resin composition. Accordingly, the polypropylene-based resin composition may be applied widely to a molded product of interior or exterior parts of a vehicle because a polypropylene resin composition containing a metal hydroxide may be used to manufacture interior and exterior products of a vehicle, thereby achieving weight reduction due to excellent foaming quality during the foaming injection and improved mechanical properties.

Polypropylene-based resin composition and method for manufacturing polypropylene composite material

The present invention provides a polypropylene resin composition in a mixture of a pellet (A) and a pellet (B), which is characterized by mixing them with various inorganic fillers and additives, wherein the pellet (A) comprises a long fiber-reinforced composite resin (a) obtained via a pultrusion impregnation process, and the pellet (B) comprises a composite resin (b) that includes polypropylene and thermoplastic elastomer. The polypropylene resin composition of the present invention can directly replace thermoplastic elastomer overmolding or painting in automotive parts to which such processes are routinely applied (e.g., interior components of the vehicle), which makes it possible to simplify and reduce the cost of the production process for such parts.

Composition of polypropylene having improved tactility and scratch resistance and methods of use thereof

Disclosed is a polypropylene resin composition for automobile interior trim parts with superior paint adhesivity and low specific gravity. More specifically, a polypropylene resin composition for automobile interior trim parts having superior paint adhesivity and low specific gravity is disclosed, wherein a base resin including polypropylene, a propylene-ethylene copolymer or a mixture thereof is mixed with a reinforcer including magnesium hydroxide and an ethylene-butene elastomer. The present polypropylene resin composition allows for direct painting of an automobile interior trim part surface without primer treatment and provides excellent resistance to damage caused by impact.
