POLYMETAC is Mitsui Chemicals’ new technology for strong adhesion and bonding of various metals and resins, a process that has not been possible using conventional methods. In adddition, POLYMETAC cuts weight and helps to reduce the number of parts and steps in the manufacturing processes, and provides totally new hybrid solutions.

The new joint parts greatly enhance the structural rigidity of aerial vehicles while significantly reducing weight and providing simpler designs by eliminating the need for fasteners such as bolts.

“Our autonomous unmanned aerial vehicles provide solutions to various industrial needs. It is important that we are able to provide greater flight distances and improved performance by reducing weight and the number of parts while ensuring durability and strength of our aerial vehicles,” says Hisashi Taniguchi, CEO of Aerosense. “Mitsui Chemicals’ POLYMETAC technology makes it possible to extend flight distance by 40%, providing our customers with greater added value.”

“POLYMETAC allows adhesion and bonding of various metals and resins, and for the current project, CFRP and aluminum parts were integrated by its technology,” says Akio Hirahara, General Manager of Mitsui Chemicals’ New Market Development (Automotive Materials) Division. “Mitsui Chemicals used its cutting edge simulation technology to design simple joint shapes with a single part which were originally composed of approximately 20 pieces. The technology contributes to a 50% weight reduction of joint parts while improving rigidity.”

Mitsui Chemicals will continue to pursue new uses and development of POLYMETAC technology for state-of-the-art lightweight solutions in automotive and electrical applications.
