SKC and SK Chemicals announced on Nov. 29 that they successfully commercialized high-value-added film made of super engineering plastic polycyclohexylenedimethylene terephthalate (PCT) for the first time in the world. PCT film is used as a core material for lightweight cables supplied to Kia Motors for electric cars.
SKC's PCT film is a film made from PCT developed by SK Chemicals. PCT is resistant to high temperature, humidity and alkali and has excellent insulation performance. So the material is used in connectors for automobile and electronic parts, and high heat-resistant fiber. Although PCT is durable, it could not be made into film because of its quick-setting property.
Based on its 42 years of know-how in film production, SKC succeeded in improving the physical properties of PCT materials and making it the world's first film by teaming up with SK Chemicals. In cooperation with automobile cable manufacturer Jin Young Global, SKC developed a flexible flat cable which is thin and light. Currently, the cable is going into the electric model of the Kia Motors’ Niro only but both companies plan to gradually expand the application of the cable and secure more buyers.
PCT film can endure up to 265 ℃ and is resistant to moisture. SKC explains that PCT film has a bright market forecast. Although the weight of cars has been greatly cut, heavy copper cables are widely used.
