[INQ. NO. 2202M15] Aromatic Diamines and Dianhydrides which are used as raw materials for Polyimide are products with high purity of more than 99.9%. Polymide has excellent mechanical strength, chemical-resistance, weather-resistance, heat-resistance, superior thermal and chemical stability, and electrical properties such as dielectric behavior.
They are key raw materials of Flexible Printed Circuit Boards (FPCBs) for various electronic equipment, Tape Automated Bonding (TAB) for semiconductor mounting, and Heat Dissipating Sheet for IT devices. Polyimide is also used as insulating materials such as motors, electric wires and insulating materials in the aviation and space industries and increasingly used as a light, flexible polymer substrate material that can potentially replace the existing glass substrate in IT devices.
Alicyclic Dianhydrides which are used as raw materials for Colorless Polyimide, are products with high purity more than 99.9% and low metal content at ppb level. Colorless Polyimide features superiority of Polyimide and transparency and is used as a flexible cover window which replaces a tempered glass for the multi-foldable, rollable IT devices.
Korea PTG Co., Ltd., is a leading company in the field of C4 stream technology and currently produces highly purified Maleic Anhydride, 1,4-Butanediol and Tetrahydrofuran (THF) with its annual capacity of 30,000 MT, respectively.
Korea PTG also become a reliable partner of the spandex, polyurethane, and plastics industries thanks to its manufacturing capability for an annual production of 30,000 MT of Polytetramethylene ether glycol (PTMEG).
