At Mitsubishi Chemical, we offer the high-performance engineering plastic film "SUPERIO™ UT". Leveraging our many years of accumulated technology and experience, we are currently mass-producing films made from PEI (polyetherimide) and PEEK (polyether ether ketone). These films have been adopted across a wide range of industries and applications, including automotive, electronics, and aerospace. To meet the increasingly diverse needs of our customers, we are actively engaged in the development and commercialization of an even broader range of high heat-resistant films. We also offer customized solutions tailored to specific customer requirements. If you are interested in high-performance engineering plastic films, please feel free to contact us.
