Global Third Generation LOW DK3 (Quartz Cloth) Market Strategic Research Report

Scope of the Report

The global Third Generation LOW DK3 (Quartz Cloth) market size is predicted to grow from US$ 122 million in 2025 to US$ 827 million in 2032; it is expected to grow at a CAGR of 31.6% from 2026 to 2032.

Electronic cloth is a key reinforcement material for copper clad laminates (CCL), which is combined with resin systems to form PCB substrates. Its dielectric constant (Dk), dielectric loss (Df), coefficient of thermal expansion (CTE) and dimensional stability jointly determine the high-speed signal transmission performance of PCB materials. Driven by the development of AI servers, high-speed switches, 800G/1.6T optical modules and next-generation high-speed interconnect technologies, PCB materials are transitioning from conventional E-glass electronic cloth toward modified low-dielectric glass cloth and third-generation quartz fiber electronic cloth. The first-generation electronic cloth mainly uses E-glass fibers, while the second-generation approach adopts modified glass systems such as D-glass, NE-glass, L-glass and T-glass to reduce dielectric loss. The third-generation electronic cloth, known as Third Generation Low DK Quartz Cloth, uses high-purity silica quartz fibers as reinforcement materials to achieve ultra-low dielectric loss and superior high-frequency transmission capability.

Third Generation Low DK Quartz Cloth is an electronic-grade quartz fiber fabric designed for high-frequency and high-speed electronic applications. Manufactured through high-purity quartz fiber preparation, precision weaving and surface treatment processes, it provides excellent uniformity and dimensional stability. Compared with conventional glass fiber cloth, Quartz Cloth offers lower dielectric constant, lower dielectric loss, lower thermal expansion coefficient and improved signal integrity, enabling next-generation PCB materials for 224G high-speed interconnects, AI servers and high-speed switching systems. Positioned in the middle stream of the high-speed PCB value chain, Quartz Cloth connects upstream suppliers of high-purity quartz materials, quartz fibers, electronic yarns and weaving technologies, while downstream it serves copper clad laminate manufacturers, PCB producers and end markets including AI servers, data centers and high-speed communication systems. CCL manufacturers such as Shengyi Technology, Panasonic Industry, Elite Material and ITEQ integrate Quartz Cloth with low-loss resin systems to produce advanced high-frequency copper clad laminates, which are subsequently used in NVIDIA GPU server platforms, AI data center infrastructure, high-speed switches, optical communication equipment and aerospace electronic systems. Currently, the global Quartz Cloth market remains at an early commercialization stage, transitioning from material development and customer qualification toward small-volume supply and large-scale capacity expansion.

In 2025, global shipments of Third Generation Low DK3 (Quartz Cloth) are estimated at 5 million meters, with an average selling price of about US$25 per meter and a manufacturing gross margin of about 40%-50%.

Third Generation Low DK Quartz Cloth Drives the Evolution of High-Speed PCB Reinforcement Materials Toward Quartz-Based Solutions

Driven by the rapid development of AI servers, 800G/1.6T optical modules and next-generation high-speed interconnect technologies, PCB materials are undergoing a transition from conventional E-glass electronic cloth toward ultra-low dielectric and high-frequency reinforcement materials. Semiconductor companies are actively advancing 224G high-speed interconnect technologies, creating increasing requirements for ultra-low-loss PCB materials used in servers, network switches and storage systems. Traditional E-glass cloth faces limitations due to relatively high dielectric loss, while second-generation Low-DK glass cloth improves electrical performance but remains constrained by the intrinsic properties of glass fiber systems. Based on high-purity quartz fibers, Third Generation Low DK Quartz Cloth provides superior dielectric performance, ultra-low loss characteristics and excellent thermal stability, making it a promising reinforcement material for advanced high-speed copper clad laminates.

Quartz fibers exhibit naturally low dielectric polarization characteristics and provide superior signal transmission performance at high frequencies. Under 10GHz testing conditions, quartz fiber demonstrates dielectric constant below 4 and significantly lower dielectric loss compared with conventional glass fiber materials, enabling compliance with advanced low-loss PCB requirements. As PCB material standards continue to advance toward higher performance levels, conventional glass fiber systems are approaching their technical limits, while quartz fiber electronic cloth provides a new pathway for next-generation high-speed interconnect materials.

The global Quartz Cloth market remains in an early commercialization stage, transitioning from technology development and customer qualification toward initial volume production. Chinese manufacturers are accelerating commercialization efforts, with companies including Hubei Feilihua, Henan Shenjiu Tianhang and Anhui Yaoshi focusing on quartz fiber and quartz electronic cloth development. Meanwhile, traditional electronic cloth leaders such as China Jushi, Sinoma Science & Technology and Grace Fabric Technology are leveraging their manufacturing capabilities and customer resources to expand into Low-DK and next-generation dielectric materials. With increasing performance requirements from AI servers, high-speed switches, high-performance computing and satellite communication systems, Quartz Cloth is expected to achieve initial penetration in premium high-speed PCB applications and gradually replace part of the high-end glass fiber cloth market.

However, commercialization of Quartz Cloth still faces significant technical and supply chain challenges. Manufacturing requires advanced capabilities in ultra-high-purity quartz fiber preparation, continuous fiber drawing, precision weaving, surface treatment and resin compatibility. In addition, the current premium pricing of quartz cloth limits adoption in cost-sensitive PCB applications. Future competition will focus on stable supply of high-purity quartz fibers, high-yield manufacturing processes and qualification capabilities with leading copper clad laminate producers.

With semiconductor manufacturing capacity increasingly concentrated in Asia-Pacific regions, particularly China, Japan and South Korea, demand for electronic-grade quartz fiber cloth with low impurity levels, high consistency and long-term reliability is expected to increase. Furthermore, aerospace, defense electronics, millimeter-wave radar, high-temperature sensors and next-generation satellite communication systems will expand demand for materials with superior thermal stability, radiation resistance and electromagnetic transparency. Overall, Quartz Cloth is expected to gradually move from the current qualification stage toward broader commercialization and become an important component of future high-performance electronic material systems.
