三菱ケミカル Product Lineup

In addition to the heat resistance and surface adhesion characteristics of epoxy resin, flexibility has been added. 【Features】 ■ Since it is already cured, it has no melting point and does not melt. ■ It does not contain low molecular weight siloxanes. ■ It excels in shock absorption and vibration damping properties. ■ It has excellent adhesion to CFRP prepregs and metals. ■ There is also an embossed type with reduced surface tackiness. ■ It is available in a thin film and can be delivered in roll form.

We would like to introduce two unique products developed by our company. "Keiju(TM)" is a high-temperature resistant cushioning material for press applications, created using our proprietary processing technology. It can accommodate ultra-thin thicknesses ranging from 50μm to 500μm and can be reused multiple times. Additionally, we have developed a "Flexible Epoxy Film" that excels in elasticity and flexibility. It is intended for a wide range of applications, including vibration damping for printed circuit boards and shock-absorbing materials for electronic components. 【Features】 <High-Temperature Resistant Cushioning Material "Keiju(TM)"> ■ Dust generation during processing is suppressed as it does not use non-woven fabric. ■ The material is backed, preventing the film from stretching in the plane direction during pressing and reducing lateral displacement. <Flexible Epoxy Film (Development Product)> ■ It has already cured, so it does not have a melting point and will not melt. ■ It does not contain low molecular weight siloxanes. *For more details, please refer to the materials.

This product is an epoxy film that complements the properties of CFRP (carbon fiber reinforced plastic), providing high vibration damping and flexibility. ■ Excellent vibration damping and shock absorption performance By laminating this film with regular carbon materials, it is possible to improve flexibility by 1.6 times and vibration damping by 5 times. When incorporated into sports equipment (such as shafts), it significantly reduces unwanted vibrations while maintaining flexibility. It contributes to enhancing the added value of products by creating a clear and soft feel during impact and operation. High shock absorption that is difficult to penetrate has also been confirmed in DuPont impact tests. ■ Strong adhesion and heat resistance The adhesion to prepreg is extremely good, making it suitable for integrated molding. Additionally, due to its cross-linked structure, it does not melt even at high temperatures of 260 degrees, demonstrating stable performance under severe molding conditions and usage environments. *For more details, please download the catalog or feel free to contact us.

This product is an insulating film that combines the "flexibility" and "process resistance" required for stretchable FPC and printable electronics. ■ High adhesion to metals and conductive inks In addition to being capable of copper foil attachment and etching processes, it adheres strongly to silver paste without surface treatment. This enables improved reliability of stretchable circuits, which was difficult with conventional materials. ■ Excellent recovery and heat resistance It has low hysteresis loss and demonstrates excellent recovery even when repeatedly stretched. Additionally, it possesses high heat resistance, capable of withstanding a reflow process at 260 degrees for 5 minutes, which is a significant feature that allows for direct application in electronic component mounting processes. ■ Enhanced design flexibility Despite being a thin film, it ensures an insulation breakdown voltage of 12kV/0.1mm (Type E) and maintains insulation performance. It can be utilized in areas where space-saving and reduced driving load are required, such as smartphone camera modules and the bending sections of foldable devices. *For more details, please download the catalog or feel free to contact us.

This product is an epoxy film developed to add high added value to thermosetting glass fiber reinforced composites (GFRP). It simultaneously improves the traditional challenges of "vibration" and "impact resistance" in GFRP components that contribute to lightweight automotive design. ■ Excellent Vibration Damping Performance and Improved Ride Quality By simply inserting a 100μm thick film between GF prepregs, the vibration damping properties of the material are significantly enhanced. It suppresses the transmission of vibrations from the tires, contributing to improved cabin quietness and ride comfort. It is effective in areas where vibration and noise are concerns, such as suspension, doors, and roofs. ■ Impact Absorption and Damage Prevention Effects In puncture tests, GFRP laminated with this film demonstrated an excellent delay in destruction effect, with maximum energy consumption doubling. Even in the event of material fracture, frictional forces work to prevent secondary damage, making it applicable as an impact-absorbing material in bumpers and crash boxes. ■ Strong Adhesion The adhesion to GF prepreg is extremely good, and sufficient strength has been confirmed in peel tests. *For more details, please download the catalog or feel free to contact us.*
