Material Design Technologies
Toray's Electronic and Information Materials business has strengths in design technologies for polymer materials, photodefinable materials, and microparticle dispersion materials. By designing material properties at the molecular level, we can meet the complex and sophisticated needs of our customers, including heat resistance, photosensitivity, and mechanical properties. In addition, we are dramatically increasing development speed by promoting DX utilizing MI (Materials Informatics), simulations, and other tools.
-
01 Polymer Materials
In addition to general-purpose resins such as acrylics and epoxies, we achieve material design with precise control of molecular structure, functional group arrangement, and molecular weight, based on Toray’s strengths in high-heat-resistant resins such as polyimides and polysiloxanes.
-
02 Photodefinable Materials
Based on high-heat-resistant polymer materials such as polyimide and polysiloxane, we can design materials with the processing characteristics required by our customers. We are also pushing the limits of ultra-miniaturization and thick-film capability.
-
03 Microparticle Dispersion Materials
Combining fine particles is an effective way to impart new functions that cannot be achieved with polymer materials alone. Toray takes an integrated approach spanning everything from fine-particle selection to dispersion stabilization design, creating high-value-added materials.
Process Technologies
Toray's strength in process technology lies not only in production technology for manufacturing products but also in solution-oriented technology that can propose the optimal materials and processing conditions for customers' manufacturing processes. Through process technology that combines the "ability to create" with the "ability to propose," we respond flexibly and accurately to the diverse needs of our customers.
-
01 Polymerization and Blending
For polymer and photodefinable materials, it is important to consistently achieve the desired physical properties and characteristics. Toray possesses advanced polymerization and blending technologies that allow for precise control of physical properties and characteristics within strict tolerances, providing stable quality and reliability.
-
02 Coating
Uniform film formation involves a complex interplay of many factors, including material viscosity and adhesion. Toray has established a highly advanced technical system for slit-coating and roll-to-roll processes, providing high-quality products with minimal variation in properties.
-
03 Photolithography Processing
Based on the photolithography process technology developed through years of photodefinable material development and manufacturing, we possess technology capable of reproducing customer processability and verifying process compatibility, including the construction of evaluation systems identical to those used by our customers.
-
04 Microparticle Dispersion Stabilization
To achieve stable particle dispersion, the dispersion method and dispersion conditions must be optimized according to particle type and size. Based on its extensive expertise, Toray possesses dispersion technology for a wide variety of fine particles.
-
05 Fiber Spinning
In the Electronic and Information Materials business, we manufacture plastic optical fibers by applying the spinning technology that Toray's textile business has cultivated over many years. We are also pursuing the limits of multi-core integration.
