Recently, Industrial Summit Technology (IST), headquartered in Shiga Prefecture, Japan, has launched an advanced new type of polyimide fiber called Imidetex, aimed at redefining the applications of composite materials.

With a high tensile strength of 3GPa, a continuous use temperature exceeding 250°C, and an ultra-low water absorption rate below 0.9%, Imidetex can bring new dimensions to composite materials, working synergistically with traditional glass fibers and carbon fibers to enhance the performance of composites.

Unlike traditional materials that require trade-offs between strength, weight, and flexibility, polyimide fibers seamlessly integrate into composite material structures, complementing and extending existing solutions.

When combined with carbon fiber or glass fiber, Imidetex can provide excellent vibration damping, improved impact resistance, and significant weight reduction without compromising structural integrity. When incorporated into composite structures, Imidetex provides enhanced performance through the following characteristics:

Electromagnetic transparency: enhancing communication performance and high-frequency support;

Low transmission loss: optimize signal quality, improve energy efficiency, and enable long-distance transmission;

Optimal Vibration Reduction: Enhancing Structural Stability and Dynamic Performance;

Impact resistance: It has high durability against external impacts and minimizes structural damage.

application

Reducing weight and structural integrity are crucial in aerospace applications, where Imidetex helps to develop lighter yet stronger components, improving fuel efficiency and durability under extreme conditions.

In addition, its excellent vibration damping performance improves stability, and its electromagnetic wave permeability makes it an ideal choice for radio wave transmission, applicable to fields such as satellite components and aircraft communication systems.

In the automotive industry, Imidetex can enhance vehicle components by reducing weight and improving impact resistance, thereby increasing fuel efficiency and lowering emissions. Integrating it into automotive composites supports next-generation transportation innovation.

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

In addition, the production process of Imidetex is green and energy-saving, with its carbon dioxide emissions being only one-fifth of those from carbon fiber production.

In addition to performance, its natural amber color provides unique visual recognition, adding new possibilities to product design without sacrificing strength or heat resistance. Imidetex enables manufacturers to combine technical advantages with design flexibility, creating a new generation of composite materials that excel in both form and function.

IST was founded in Shiga Prefecture, Japan in 1983, and established its US branch in Paramus, New Jersey in 2000. By acquiring the Pyre-ML and Skybond businesses, IST expanded its operations to provide polyimide products to various industries.
