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.

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.
I.S.T. has successfully developed “IMIDETEX®,” a super-fiber based on a unique ultra-violet stable and high temperature resistant polymer, to grant the dream features in equipment and parts.
The fiber has very high tensile strength and modulus allowing products made of the fiber to stand heavy loads. For example, the rope made of IMIDETEX® is 80% lighter than steel ropes of comparable strength. IMIDETEX® also has low water absorption and excellent UV resistance, which make it possible to play active roles in various fields including outdoor and sports scenes in harsh environments that other conventional para-aramid fibers could not fulfill.
*IMIDETEX is a I.S.T’s registered trade mark.
・High tensile strength of 3.0GPa.
・Low water absorption of less than 0.9%.
・Ultra-high UV resistance. (100% intensity after radiation equivalent to 4 months of sunlight)
・High temperature resistance as over 250℃ of consistent use.
IMIDETEX® creates outstanding features of unprecedented performance in the sports world.
For example, climbing Mont Blanc, air sports soaring into the sky, intense sailing in America's Cup. We aim to realize safer products in harsh environments.
IMIDETEX® has high strength. Compared with other para-aramid fiber, it has UV resistance and low water absorption.
The amount of UV rays in the mountains increases by 10% for every 1000 m above sea level. In particular, fresh snow reflects 80% of ultraviolet rays.
Therefore, it is suitable for use in high altitude mountains and ropes used in harsh mountain climbing with snow.
IMIDETEX® has not only high tensile strength, UV resistance, and low water absorption, but also heat resistance and flame resistance that exceeds those of para-aramid fibers.
For theseis reasons, IMIDETEX®it is a desirable choice for membrane applications such as sailboat sails and high-altitude mountain tents to protect from high UV rays and some flame uses.
・Various ropes, lines, knits, gloves
・Heat resistant tire cords
・Yacht sails, Sky sports sails, Tents,
・High temperature duct parts
・Heat resistant bug filters
As composite parts:
・Aircraft engine peripheral parts
・Various automotive parts
Currently, fiber-reinforced plastic (FRP) is formed mostly with carbon fiber and 180 °C curing type epoxy resin. Until now, there has been no high-strength resin fiber that does not deteriorate when cured at 180 °C.
Heat resistant polyimide resin fiber IMIDETEX® that exceeds up to 250 °C can be made into FRP, making it possible to design a new FRP material that has high strength with impact resistance. Such a product can be supplied for the fragility of carbon fiber and absorbing vibration and shock. Also, by curing IMIDETEX® with polyimide resin for FRP from IST, can bring a whole new revolution in the GRP industry.
For example, it opens up new possibilities for FRP, such as heat protection for sports equipment such as golf shafts, aircraft engine blades, and automobile storage batteries.
