ILJIN Materials Co., Ltd. produces and sells elecfoils in Korea and internationally. Its elecfoils are used as core material for electronic products. The company offers I2B that creates the anode current collector of lithium secondary battery; and IHT, a high bending low illuminance elecfoil for FPCB; and UTC, a very thin elecfoil developed suitable for microcircuiting, high density, high integration, and high multilayering of PCBs. The company also provides I2K, an elecfoil used as a negative electrode collector for small lithium secondary batteries; VLP, a special elecfoil with low illuminance and high strength characteristics used for integrated circuit packaging substrates for semiconductor mounting; ICS, a general-purpose product used as the main material for printed circuit board and copper clad laminate; and I2S to expand the capacity of the secondary battery. In addition, it offers ISS a higher tensile item that is being considered for application of next-generation secondary batteries; HVLP elecfoil suitable for high-speed transmission; and TRT/HRT elecfoils used for base station antennas. The company was formerly known as Iljin Elecfoil Co., Ltd. and changed its name to ILJIN Materials Co., Ltd. in 2010. ILJIN Materials Co., Ltd. was founded in 1987 and is headquartered in Seoul, South Korea.
