Heat-resistant, high-strength, low moisture absorption! Super fiber with a strength of 3.0 GPa and a continuous use temperature of over 250°C.
I.S.T has developed a high-strength polyimide fiber called "IMIDETEX" using its unique technology. It achieves a high strength of 3.0 GPa and can be continuously used at temperatures exceeding 250°C, making it a super fiber. Furthermore, with a low water absorption rate of less than 0.9%, it is a new material that holds potential for various fields, including outdoor and sports scenes under harsh conditions that conventional para-aramid fibers could not meet. 【Features】 ■ High strength of 3.0 GPa ■ Low water absorption rate of less than 0.9% ■ High heat resistance allowing continuous use above 250°C *For more details, please refer to the PDF document or feel free to contact us.

【Heat Resistance and Flame Retardancy】 IMIDETEX not only has high strength and low water absorption but also possesses heat resistance and flame retardancy that surpasses para-aramid fibers. Therefore, it is suitable for membrane applications such as high-altitude mountain tents and yacht sails, making it a material that can be safely used when fire is involved.

"Enabling vibration control and reinforcement with heat-resistant FRP" Currently, fiber-reinforced plastics (FRP) primarily use carbon fibers and 180°C curing epoxy resins, and until now, there have been no high-strength resin fibers that do not degrade at 180°C curing. Heat-resistant polyimide resin fibers, IMIDETEX, which can withstand temperatures above 250°C, can be used for FRP. This compensates for the brittleness of carbon fibers and absorbs vibrations and impacts, allowing for the design of new FRP materials that combine high strength and impact resistance. Additionally, by curing IMIDETEX with I.S.T's polyimide resin for FRP, it is possible to create a new FRP made entirely of polyimide resin. For example, it expands the new possibilities of FRP in sports equipment such as golf shafts, as well as in aircraft engine blades and heat protection for automotive batteries.
