[News] Nittobo Expands Glass-Fiber Output with Nan Ya; Nan Ya to Handle 20% by 2027 Amid AI Surge

With AI demand surging, electronic materials suppliers are aggressively expanding to capture the market. Nan Ya Plastics announced today that it has formed a strategic partnership with Japan’s specialty glass-fiber giant Nittobo to jointly expand supply capacity and meet rapidly growing market demand.

Nan Ya Plastics states that by 2027, it will be responsible for weaving 20% of the specialty glass-fiber fabrics that Nittobo supplies to the global market.

Nan Ya Plastics—part of the Formosa Plastics Group—operates one of the world’s largest glass-cloth manufacturing capacities within its Electronic Materials business, as highlighted in press release from Nittobo.

As noted in the press release, beyond production collaboration, Nittobo will also provide Nan Ya Plastics with long-term and stable supplies of key raw materials for the company’s second-generation low-dielectric-constant glass yarn (NER). This will strengthen Nan Ya Plastics’ competitiveness in high-end CCL (copper-clad laminate) products and accelerate its expansion into the advanced electronic materials market.

Benefiting from the AI server boom, printed circuit boards (PCBs) have become increasingly critical—and glass-fiber fabric is one of their key materials. As TechNews notes, Nittobo is the world’s only company capable of stably mass-producing top-grade T-Glass.

According to TechNews, the surge in T-Glass demand stems from its role in next-generation PCB materials. Low-dielectric-constant (Low-Dk) glass fabrics help reduce signal loss and improve high-temperature stability. Among them, T-Glass, with its low coefficient of thermal expansion (Low-CTE), effectively prevents substrate warpage during advanced packaging, significantly improving AI chip yield and heat-dissipation performance.
