Our products are used in a diverse range of applications, from food and other packaging to industrial materials requiring sophisticated technology, and play a useful part in everyone’s daily lives. We also offer an extensive lineup of Environmental Contribution Products that take full advantage of cutting-edge technology. We will continue to develop products that benefit society and push further ahead as a top manufacturer.
New Materials Division
The New Materials Division has a vision to “launch key parts to the world”. Building on our long-standing film-forming technology, the divis ion delivers high functional products to our customers around the world. Such products include optical films for smartphones and TVs and urethane elastomer films for automobile parts and medical use. We will continue to promote our products in areas and fields tha t are constantly evolving and have significant social needs, such as the information electronics field, the functional materials for manufacturing processes field in automotive industry, and the life science field in medicine and welfare.
Building Materials Division
The Building Materials Division offers various materials for houses, furniture, and other products widely used in daily life. Our advanced technology, based on the decorating and processing techniques we have developed over time, is friendly to living space. We also offer safety and security for business space by providing materials.
Research and Development Center
By combining the elemental technologies we have cultivated, we are engaged in research and development to create attractive products that meet the demands of users.
■ Development Direction
■ Core Tecnology
-
Film-forming
Film forming technology involves melting various resins in an extruder, extruding them through a die, and cooling the extruded resin to obtain film.
-
・Inflation
Molten resin is extruded from an inflation die into a tube shape, air is blown into the tube to inflate it like a balloon, and the film is cooled and rolled while being pulled by rollers.
-
・T-die Casting
Molten resin is fed into a T-shaped die, and after the resin is spread to both ends of the die at the manifold, it is discharged from the lip voids in the form of a film. The film is then cooled by cooling rolls and rolled up.
-
-
Stretching
This technology is used to modify the physical properties of a heated film by stretching it longitudinally or transversely and aligning the molecules, thereby adding new functions to the film. Our techniques include longitudinal stretching, transverse stretching, tubular stretching, and sequential biaxial stretching.
-
Coating
Technology to precisely coat, dry, and cure a solution of formulated materials on the surface of a film to impart optical and physical functions.
-
・Die Coating
This method coats the film while pushing the coating agent out of the die.
-
・Reversed-Gravure Coating
In this method, the gravure roll is rotated in the opposite direction to that of the substrate, the rotating gravure roll scrapes up the coating agent, the doctor blade scrapes off excess coating agent, and the coating agent is coated onto the film.
-
-
Printing
This technology is used to modify the physical properties of a heated film by stretching it longitudinally or transversely and aligning the molecules, thereby adding new functions to the film. Our techniques include longitudinal stretching, transverse stretching, tubular stretching, and sequential biaxial stretching.
-
・Flexo Printing
A method in which ink is supplied to a convex plate and pressure is applied from the film side to transfer and dry the ink on the convex to the film.
-
・Gravure Printing
A method in which ink is supplied to an intaglio plate, excess ink is scraped off with a doctor blade, and pressure is applied from the film side to transfer and dry the ink in the concave area onto the film.
-
-
Lamination
Technology to develop multilayer films with composite performance by bonding films with different functions using adhesives or molten resins.
-
・Dry lamination
Method of laminating film to film or film to metal using adhesives.
-
・Extrusion lamination
Method of laminating film to film or film to metal by feeding molten resin from an extruder.
-
-
Pressing
Technology to develop multilayer films with composite performance by bonding films with different functions using adhesives or molten resins.
-
Extraction
This technology selectively separates specific components from liquids, individuals, and other materials efficiently and at high concentrations.
