Advanced Materials

KCC's Advanced Materials are the solutions for the future.

Organic material Inorganic material Glass fiber

Glass fiber to reinforce the properties of plastics

Glass fiber is a composite material with a thickness of ㎛ where the filaments created from the glass melted with inorganic materials including agalmatolite and limestone at extremely high temperatures of over 1500℃ are surface treated.

Commodity plastics: Brittle, red-short
low dimensional stability

Glass fiber: The KCC’s composite materials

Bolster insulation, dimensional stability, and properties.

Reinforced plastics: High physical strength

The glass fiber produced by the KCC includes the Chopped Strand, Chopped Strand Mat, Direct Roving, Conventional Roving, Woven Roving, and Tissue. It is widely used across the electric·electronic, automotive, and civil engineering industries.

Glass fiber for automotive parts

The development of green car manufacturing technology rises due to the enhanced global environmental regulations and increasing oil prices. The engineering plastics used to reinforce automotive interior/exterior materials can provide various physical properties including being lightweight (by replacing the existing metal materials), dimensional stability, heat insulation the heat resistance (required to an engine), corrosion resistance, chemical resistance, and hydrolysis resistance.

Application

Electric vehicle components : Connectors, actuators
Interior materials : Seat support, ceiling stiffeners, major parts surrounding a driver’s seat, gears
Exterior materials : Car body, reinforced structures, various automotive modules (front, rear, door module), under cover guard, etc.
Engine/fuel parts : Radiators, intake manifold
Railway vehicle flooring, bus body, freight containers, trucks, spoiler

Glass fiber for Manufacturing the FRP ship hull

The strength of the KCC’s glass fiber is strong and we can implement the lightweight design. With its excellent chemical resistance, water resistance, and corrosion resistance, it is widely used in various lightweight materials including the FRP ship hull. By replacing the existing metal materials (steel, stainless steel, and alloy), various designs can be implemented, the construction period can be shortened, and maintenance costs can be saved.

Application

Manufacturing the FRP ship hull/superstructure

Glass fiber for manufacturing chemical/industrial materials

The KCC’s glass fiber products boast their long service life despite harsh conditions as a material suitable to various industries where corrosion resistance and durability are required. They can be implemented as various designs along with outstanding exterior expressions. By replacing the existing metal materials (steel, stainless steel, and alloy), various designs can be implemented, the construction period can be shortened, and maintenance costs can be saved.

Application

Wastewater treatment plants, anti-corrosive tanks, industrial containers, sewage disposal tanks, pipes(for line, sewer, gas), utility poles, insulators, concrete reinforcement, and structures(guard rails) in highway facilities

Major laws /regulations	Major details and guidelines
Fair Trade Act	The prohibition of unfair trade practices: One shall not use one’s superior position in trade to give disadvantages to the suppliers(Refusal of transaction, discriminatory treatment, forced trade, abuse of dominant position, constraint trade and the act of maintaining the resale price). The prohibition of abusing one’s dominant position in the market: In case of a dominant market player, one shall neither determine, maintain or change the price or payment for the services unfairly nor interfere in the business activities of another business or the entrance of a new competitor. One shall neither do trades to unfairly eliminate the competitors nor behave in a way that may harm the interests of the consumers. The prohibition of unfair common action(collusion): One shall not agree on the matters of restricting the competition such as restricting the competitor, price, production/sales quantity, trading area/opposite party, etc. One shall not exchange sensitive information that may have an impact on these matters directly or indirectly. The prohibition of an unfair common action(bid rigging): In the bidding process, one shall not discuss/agree on a prospective successful bidder and the bidding price with another party prior to the bidding. One shall not share the bidding information with the competitors. The control of suppressing the concentration of the economic power: One shall avoid unfair internal transactions among affiliates.
