A thermoplastic resin composition contains a styrene-methyl methacrylate-butyl acrylate copolymer and thus exhibits improved blackness and scratch resistance, and a molded article including the same.

Thermoplastic resin composition having improved blackness and scratch resistance, and molded article comprising the same

A metallic unpainted injection molding for a vehicle is disclosed. The metallic unpainted injection molding for a vehicle is molded by injecting metallic resins into a molding part inside an injection mold through a plurality of gates to be molded, wherein at least a groove line is molded in a boundary section where metallic resins meet each other in the molding part.

Metallic non-painting injection molding for vehicles

A lighting apparatus for vehicles which may provide a unique and beautiful image of an electrified vehicle and aesthetic sensibility, and a method of manufacturing the same, include a light source configured to emit light, a light guide plate configured to diffuse the light emitted by the light source, and a lens cover configured to transmit the light diffused by the light guide plate and to emit the light forwards of the light cover, and irregularities configured to form thickness differences of the lens cover depending on a position on the lens cover or a portion of the lens cover are formed on an internal surface of the lens cover configured so that light having passed through the light guide plate is incident thereupon.

Lighting apparatus for vehicles and method of manufacturing the same preliminary class

Disclosed area coating-free metallic thermoplastic resin composition having improved metallic texture and gloss and a molded product having extrusion-molded the same. For example, the molded produce may be manufactured by feeding a master batch containing a styrene-acrylonitrile (SAN) resin and a metal in a weather resistant thermoplastic resin containing an acrylonitrile styrene acrylate (ASA) resin in a side feeding method. The coating-free metallic thermoplastic resin composition may be optimized in types and contents of the master batch and dispersant contained therein. The molded product may be manufactured by feeding the master batch in the side feeding method to improve various physical properties, increase the dispensability and compatibility between compositions, and improve black streaks and flow marks, thereby improving metallic texture and gloss as well as suppressing the occurrence of the appearance defects.

Coating-free metallic thermoplastic resin composition having improved metallic texture and gloss

A metallic polypropylene resin composition is provided herein. The metallic polypropylene resin composition provides appearance characteristics that are similar to those provided by painting, but without painting. The metallic polypropylene resin composition of the present invention has excellent physical properties such as scratch resistance, and thus may be applied to molding methods, such as a molded in color (MIC) method. The resin composition is useful as a material for automobile interior and exterior parts, as wells as electric and electronic products, which can be molded by the MIC method.
