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.
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.
SKYBOND 8000 is a polyimide high heat-resistant resin used for RTM (Resin Transfer Molding) independently developed by I.S.T.
Using I.S.T's polyimide resin and FRP forming technologies, we open a future of heat-resistant composite materials in various fields, such as the aerospace and general industry fields.
SKYBOND 8000, when combined with various reinforcement fibers, actualizes heat-resistant composite materials suitable for applications.

Conventionally, FRP (fiber reinforced plastic) is formed using polyimide resin by impregnating carbon cloth with varnish, and drying the cloth to generate prepregs. Then, the prepregs are laminated, and heated/cured by removing solvent and/or condensation water in a vacuum using large equipment, such as autoclaves. However, this method requires high-level process technology, and it is likely to develop more voids (vacancies), which is a disadvantage.
I.S.T has successfully shortened these processes, and developed a new type of polyimide resin as well. Using our polyimide resin, polyimide carbon FRP with very few voids (vacancies) can be made through injection forming.
