(I.S.T., Shiga, Japan and Parlin, N.J., U.S.) launches Imidetex. The polyimide fiber — with properties such as high tensile strength (3.0 GPa), a continuous use temperature exceeding 250°C and an ultra-low water absorption rate (<0.9%) — has been engineered as a “super fiber” for the most demanding environments. 

Imidetex has been designed to work in synergy with traditional glass and carbon fibers, enhancing their performance with its own balance of lightweight strength, durability and multifunctional properties. Unlike conventional materials that require trade-offs between strength, weight and flexibility, I.S.T. reports that Imidetex integrates seamlessly into composite structures, complementing and expanding the functional capabilities of existing solutions.

When combined with carbon or glass fibers, Imidetex provides vibration damping, improved impact resistance and weight reduction without compromising structural integrity. This complementary nature enables composites to meet more demanding specifications in industries such as aerospace, automotive, telecommunications and high-performance sports equipment.

When incorporated into composite structures, Imidetex delivers enhanced performance through these following properties:

• Electromagnetic transparency: Enhances communication performance and high-frequency support.
• Low transmission loss: Optimizes signal quality, increases energy efficiency and enables long-distance transmission.
• Optimal vibration damping: Improves structural stability and dynamic performance.
• Impact resistance: Provides high durability against external impacts and minimizes structural damage.

Additionally, Imidetex retains the inherent properties of polyimide, including high heat resistance, low water absorption and high strength.

Because of its ability to enhance rather than replace existing materials, I.S.T. believes Imidetex can unlock new opportunities in fields like telecommunication devices (5G/6G, RF equipment), sports equipment (protective gear, high-performance devices), automotive and mobility, public infrastructure, medical devices, and aerospace and satellite technologies.

Beyond performance, Imidetex offers designers a distinctive aesthetic appeal. Its natural amber hue provides a distinctive visual identity, adding new possibilities for product design.

As industries increasingly prioritize sustainability, Imidetex also acts as an environmentally responsible solution. With high durability and an extended lifespan, it contributes to longer-lasting composite structures, reducing material waste and minimizing the need for replacements.

Additionally, the polyimide fiber is reported to be significantly more energy-efficient in production, generating approximately one-fifth of the CO_â‚‚ emissions associated with carbon fiber manufacturing.
