KCC’s glass fiber products are applicable to the construction materials requiring diverse designs and durability. It is possible to achieve a lightweight, reduce the construction period, and decrease the maintenance costs by replacing the existing metal materials(steel, stainless steel, alloy). For interior construction materials, the products can be used in PVC flooring, gypsum board, and interior materials. For exterior construction materials, they can be used in eaves, roofing, structures, and formwork.

KCC provides packaging materials that are applied to the packaging process to mount semiconductor devices and protect them from the external environment. We manufacture encapsulants for protecting chips, adhesives for bonding semiconductor chips to substrates or lead frames, and Ceramic Substrates for power semiconductor modules. Nowadays, semiconductors are an essential element of all electronic devices. The need for high-density, high-integration, and lightweight, compact and compact package technology increases according to the trend of electronic products requiring miniaturization, high performance, and multifunctionality. We provide our customers with a competitive total semiconductor packaging solution.

By replacing the existing metal materials(steel, stainless steel, and alloy), the KCC’s glass fiber products implement various designs, reduce the construction period, and save on the maintenance costs. With its superior chemical resistance, water resistance, and corrosion resistance, they are used as various lightweight materials. They are also used in manufacturing the FRP ship hull and superstructure.

Of parts used in the energy, medical, aerospace, and defense industries, KCC manufactures metallized ceramic products applied to the parts requiring excellent adhesion and vacuum tightness. KCC's fiber glass is a material suitable to various industrial sites requiring corrosion resistance and durability. It also satisfies long-term use even in harsh conditions. Various designs can be proposed to diverse industrial materials. The excellent appearance is possible. Thanks to compatibility and replaceability with the existing metal materials (steel, stainless steel, alloy), the fiber glass is able to reduce weight, shorten the construction period, and reduce maintenance costs. Applications: Wastewater treatment plant, corrosion-resistant tank, industrial storage container, septic tank, pipe (oil pipe, sewage pipe, gas pipe), electric pole, insulator, concrete property reinforcement, highway facility structure (guard rail)

The number and types of automotive electronic components are increasing significantly as the market for eco-friendly and autonomous vehicles including the number of electric vehicles increases. KCC provides encapsulants and Ceramic Substrates for semiconductors and power modules, ceramic housings for power relays, and long-fiber composite reinforced materials for engineering plastics used as a replacement for metal/iron to reduce the weight of vehicles. We provide a wide range of electrical and electronic materials satisfying our customers' requirements of a higher performance and more functions with the development of technologies for EV, ADAS, and other applications.

As electronic devices and components have become more functional, semiconductors and power electronics are also required to have higher performance. KCC accelerates the development of high-performance materials to respond to a market demand for the EMC, adhesives and Metallized Ceramic Substrates. We also provide metallized ceramic housing products with excellent insulation and hermetic sealing for VIs (Vacuum Interrupters). KCC's fiber glass has the mechanical performance of various parts including excellent electrical insulation, electromagnetic shielding, durability, heat resistance and dimensional safety, which are shown in the main parts of housing/back panels of display monitors, TVs, computers, washing machine tubs, and BLU (Back Light Units)., etc.
