A manufacturing method of a symbol button for a vehicle includes: preparing a button body comprising a side portion, a top portion formed of a polymer material on which a metal is able to be plated; forming an electrically conductive layer on an outside of the button body using a conductive polymer material; forming a plating shielding layer in a form of a symbol using a material on which a metal is not able to be plated on the electrically conductive layer; and performing metal plating on the outside of the button body having the plating shielding layer.

Symbol button for vehicle and manufacturing method thereof

A thermoplastic resin composition includes base resin, which includes a polycarbonate resin and an acrylonitrile-butadiene-styrene (ABS) resin, and an additive. The ABS resin includes a rubber-modified vinyl-based graft copolymer resin, an aromatic vinyl-vinyl cyanide-based copolymer resin. The polycarbonate resin has a weight-average molecular weight of 20,000 g/mol to 40,000 g/mol, and the rubber-modified vinyl-based graft copolymer resin comprises 50 wt % to 60 wt % of polybutadiene rubber based on a total wt % of the thermoplastic resin composition.

Thermoplastic resin composition and molded product produced using the same and having improved plating adhesion and light transmittance

A symbol button for a vehicle includes: a button body; a button surface portion positioned at an upper portion of the button body; a symbol printing portion positioned on the button surface portion; an anti-plating portion positioned at a lower portion of the button body; and a metal plating layer positioned at the outside of a button excluding the symbol printing portion and the anti-plating portion.

A method of manufacturing a doorstep or a door scuff is provided. The method includes an ABS material injection step of injecting an acrylonitrile butadiene styrene (ABS) material to have a doorstep (or a door scuff) shape; a plastic plating step of plating an ABS material with plastic; and a PP injection step of fixing the ABS material plated with plastic in a mold, and injecting PP to the ABS material fixed in the mold so that the ABS material and a polypropylene (PP) material have a one-piece structure.

Method of manufacturing doorstep or door scuff

Disclosed is a polylactic acid composition with improved heat-resistance and improved impact-resistance. Specifically, in the disclosed polylactic acid composition, both impact strength and heat-resistance are improved by mixing 30 to 80 wt % of polyketone and 10 to 40 wt % of modified rubber. The disclosed polylactic acid composition does not only exhibit excellent in heat resistance, chemical resistance, fuel permeation resistance, abrasion resistance, etc., but also has improved impact-resistance and improved heat resistance. Thus, it is possible to employ polylactic acid as a bioplastic in interior/exterior parts of a vehicle.

Polylactic acid composition for automobile parts

The present invention provides a polyketone composition having about 40&#x2dc;90 wt % of polyketone, about 5&#x2dc;40 wt % of polyamide, and about 5&#x2dc;20 wt % of modified rubber. The composition of the present invention greatly improves the impact resistance of polyketone, which has increased heat resistance, chemical resistance, fuel permeation resistance, abrasion resistance or the like, and thus may be widely applied in various industrial fields, such as automotive parts including wheel covers, wheel caps, fuel filler necks, fuel tanks, fuel tubes, center fascias, door handles, roof rack covers, gear, junction boxes, connectors, seat backs or the like, electric/electronic parts, and household items, thereby providing durability of the parts and price competition.

Composition of polyketone with high impact strength

Disclosed is a thermoplastic polyolefin (TPO) nanocomposite composition, more particularly a TPO nanocomposite composition including a polypropylene resin, a polyethylene resin, a rubber resin, a nanoclay master batch and a glass bubble master batch. Since the disclosed TPO nanocomposite composition has low specific gravity and superior gloss reducing effect and scratch resistance, it may be usefully applied to light automobile parts, uncoated automobile exterior parts, or the like.

TPO nanocomposites and methods of use

Disclosed is a coating agent for poly(methyl methacrylate) (PMMA) panel nano imprinting, more particularly, a coating agent for PMMA panel nano imprinting comprising a UV curable resin, a photoinitiator, an additive for surface modification and a weather-resistant stabilizer.

Coating agent for poly(methyl methacrylate) panel nano imprinting and methods of use

An adsorptional heat pump for using as a cooler or a heater which comprises a pair of rotary module discs and plurality of thermosyphons. The rotary module discs comprise a plurality of modules of which each of two modules are positioned in order to be opposite with each other. The thermosyphon is positioned between the two opposite modules, so that both ends thereof are respectively inserted into corresponding modules and has a good heat transferring feature, so that the thermosyphon provides an internal heat exchange between the modules. The heat pump according to the invention repeatedly and periodically carries out consequent processes such as generation. .fwdarw.heat exchange.fwdarw.adsorption.fwdarw.heat exchange.fwdarw.generation. The present invention can provide a heat pump having a promoted efficiency.
