Our aim is to bring you a hearty smile and abundance of life.
We are a "group thinking of technology" looking ahead to the future, and always take on new research development. Technical employees, who make up about one third of all our employees, work in research and technology development.
I.S.T recognizes that it’s essential to integrate environmental, social, and economic structures of sustainable measures into our business and its future work structure.
Reshape common sense. We develop new materials that are world firsts, and contributing to the world. And furthermore to the universe. We hope that the materials we generate will be given life and utilized to lead to significant world improvement.
I.S.T's own technology has increased its need on a global scale, and we’ve expanded our activity locations. The network that connects research development, production, and sales at each location responds rapidly to the accelerating change of the times.
We are a group that is always thinking and constantly trying out new things. After each of us aggressively puts ideas out, we give a concrete shape to them, and manufacture things to be of advantage to companies and the world.
As a general sales agency of I.S.T Corporation, we sell various functional products, such as heat-resistant polyimid resin, office automation equipment parts, FRP parts, nonflammable function textile products, and clothing textile products.
Varnish is used to form a polyimide membrane with heat and voltage resistance, as well as having high-level mechanical strength. This material is used in a wide range of fields, such as electric wire coating materials for airplanes, as well as for medical tubes, due to its excellent features.
Polyimide varnish is used for heat-resistant and high strength compound materials, with many actual usages being achieved in airplanes. This material has the most thermal stability and adhesive properties among currently commercialized and mass-produced high-polymer materials.
High heat-resistant polyimide resin is based on I.S.T's proprietary techniques, which are used to form RTM (Resin Transfer Molding). Polyimide carbon FRP with very few voids can be made through injection forming.
A compact light-weighted polyimide foam with heat resistance and a low dielectric constant. The foam density can be controlled, and a wide range of foams from a 100 micrometer-thick thin film (sheet) to thick film (block) can be manufactured.
High heat-resistant polyimide composite with excellent thermal conductivity. This composite, which is lighter than metals, has the combined properties of a high glass-transition temperature derived from polyimide resin, and an extremely low CTE and high thermal conductivity derived from carbon fabric.
Binder for lithium-ion battery silicon anodes. This material has excellent adherence properties for copper foil and silicon alloy, and 97% of battery capacity can be retained after 400 cycles of charging and discharging.
Transparent polyimide film with a heat resistance of 300ºC and visible light transmission of 90% or more. We have also developed in-house equipment that is used to form film into a continuous roll, and have prepared the production system.
Heat-resistant and high strength seamless tube. This material is widely used in Japan and abroad for such applications as office automation equipment (copiers, printers), transfer/drive mechanisms of precision equipment, laminated belts in the high temperature range, and insulating sleeves.
Heat-resistant, high strength, and low hygroscopic polyimide fiber. This is a super fiber with a 3.0 GPa strength, and a continuous service temperature of 250ºC or more.
Here you can download PDFs of the Safety Data Sheets（SDS） for our products.
We develop new materials under our motto of developing things that are world firsts. We continue to utilize next-generation themes through joint research with universities and institutions in Japan and abroad, as well as our own development of independent equipment.
TORMED Transparent Polyimide Film based on aromatic polyimides is a high-performance film with excellent light permeability and heat resistance, a high mechanical strength and it also provides high resistance to solvents.
I.S.T has independently developed transparent polyimide resin by taking advantage of our polyimide synthesis technology, and has prepared the production system, even by developing equipment that is used to form it into continuous roll film in-house.
*TORMED is a registered trademark of I.S.T Corporation.
Visible light transmission of 90% or more, with UV rays 100% filtered out
・High heat resistance
With a glass-transition temperature of 300°C, this product provides exceptional thermal stability
・High resistance to solvents
This product is not affected by most solvents, and provides high stability
Different from typical polyimide, TORMED is capable of keeping its transparency, which results in the brightness of products being maintained.
We hope you will evaluate its excellent properties derived from aromatic polyimides, with high transparency, and consider its applications, such as for various circuit boards, optical or display devices, and lighting equipment.
・FPC (flexible print circuits)
・Displays, Touch panels (OLED, LCD)
・Solar battery panels (protective-surface cover films, base materials)
・Lighting equipment (organic EL lights, LED lights)
・as well as semiconductor related fields, and more.
TORMED Type S
Standard grade of TORMED. Uses ranging from FPC to displays.
The highest grade of transparency specialized for displays, it also exhibits excellent flexibility.
