At last week’s JEC World 2025 in Paris, Shiga, Japan headquartered Industrial Summit Technology (IST) launched Imidetex – an advanced new polyimide fibre engineered to redefine composite applications.

With exceptional properties such as high tensile strength of 3 GPa, a continuous use temperature exceeding 250°C, and an ultra-low water absorption rate of under 0.9%, Imidetex can introduce a new dimension to composite materials, working in synergy with traditional glass and carbon fibres to enhance their performance and unlock unprecedented applications.

Unlike conventional materials that require trade-offs between strength, weight and flexibility, the polyimide fibre integrates seamlessly into composite structures, complementing and expanding the functional capabilities of existing solutions.

When combined with carbon or glass fibres, Imidetex can provide superior vibration damping, improved impact resistance and significant weight reduction without compromising structural integrity.

Applications

Weight reduction and structural integrity are critical in aerospace applications where Imidetex can contribute to the development of lighter yet stronger components, enhancing fuel efficiency and durability in extreme environments. Additionally, its superior vibration damping properties improve stability, while its electromagnetic transparency makes it ideal for applications where radio wave transmission is essential, such as satellite components and aircraft communication systems.

In the automotive industry Imidetex can enhances vehicle components by reducing weight and improving impact resistance, contributing to better fuel efficiency and lower emissions. Its integration into automotive composites supports next-generation transportation innovations.

In the sports industry, Imidetex can also significantly improve vibration absorption and weight reduction, making it particularly well-suited for high-performance equipment such as skis, rackets and protective gear.

Imidetex is is also highly energy-efficient in production, generating approximately one-fifth of the CO2 emissions associated with carbon fibre manufacturing, for example.

Beyond performance, its natural amber hue provides a unique visual identity, adding new possibilities for product design without sacrificing strength or heat resistance. Imidetex enables manufacturers to combine technical excellence with design flexibility, creating next-generation composite materials that stand out in both form and function.

Founded in 1983 in Shiga, Japan, IST, established a US arm in Parlin, New Jersey, in 2000. Through the acquisition of the Pyre-ML and Skybond businesses, IST has expanded its operations, manufacturing and selling polyimide products for a wide range of industries.
