Deep‑cultivating the High‑Frequency Electronic Glass Fiber Track | Liaoning Pengda Technology Conducts Targeted Research on Downstream Demands at Shanghai Composite Materials Exhibition

From September 1 to 3, the 29th China International Composite Materials Industry & Technology Exhibition was successfully held at the National Exhibition and Convention Center (Shanghai). As a professional visitor, Liaoning Pengda Technology participated in the entire exhibition and conducted in‑depth on‑site visits. Focusing on the booming segments of low‑dielectric electronic yarns and high‑frequency high‑speed electronic fabrics, the company precisely investigated downstream production processes and raw‑material requirements. It held face‑to‑face communications with mainstream glass‑fiber enterprises in the industry to consolidate the application‑orientation of high‑end boron‑based materials.

With the rapid evolution of 5G communications, AI servers and high‑frequency high‑speed PCB industries, low‑dielectric and low‑loss electronic glass fiber has become an essential core requirement for the upgrading of electronic base materials. Unlike the boron‑free formula of conventional general‑purpose glass fiber, high‑frequency low‑dielectric systems such as D‑glass and L‑glass rely on high‑purity boron sources to stabilize formula structures. By precisely adjusting boron trioxide content, the dielectric constant and dielectric loss can be effectively reduced to ensure high‑speed, low‑latency transmission of high‑frequency signals. It serves as an indispensable key raw material for manufacturing high‑grade electronic yarns.

At the exhibition, the team paid key visits to leading domestic enterprises producing electronic glass fiber and special low‑dielectric glass fiber, gaining deep insights into industrial production standards and technical pain points:

✅ Strict specifications for boron sources required by high‑end low‑dielectric production lines: low sodium, low iron, high purity and controllable impurities;

✅ Improvement effects of ultra‑fine, high‑stability boron trioxide on melting uniformity of glass fiber and consistency of dielectric performance of finished products;

✅ Practical demands from downstream manufacturers for stable supply, customized specifications and iterative sample testing.

Through this in‑depth front‑line communication, Liaoning Pengda Technology further confirmed that high‑purity boron trioxide acts as a core additive for quality upgrading of low‑dielectric electronic yarns and represents a key growth market within the high‑end electronic glass‑fiber sector.

Rooted in real‑world market demands, Liaoning Pengda Technology will keep focusing on boron‑based raw materials dedicated to high‑frequency electronic glass fiber. The company will continuously optimize product purity, particle‑size stability and batch‑to‑batch consistency to accurately meet the industrial production standards for low‑dielectric electronic yarns and high‑frequency high‑speed electronic fabrics. It will deliver more professional and stable raw‑material solutions for downstream glass‑fiber manufacturers, jointly empowering the high‑quality development of the high‑end electronic new‑material industry.
