As global information and communication technologies steadily advance from 5G to 6G, mobile networks are rapidly evolving toward ultra‑high bandwidth, ultra‑low latency, and ubiquitous coverage. Against this technological backdrop, signal transmission frequencies have expanded from the centimeter‑wave band to the millimeter‑wave range and are now beginning to extend into the terahertz (THz) spectrum. This leap in frequency imposes extremely stringent physical‑performance requirements on the signal carriers—printed circuit boards (PCBs) and their core material, copper‑clad laminates (CCLs). In this field, Hydrocarbon resin With its unique molecular structure and outstanding electrical properties, it is emerging as a next-generation critical material, serving as an essential cornerstone in paving the way for the 6G era and the advent of high-performance computing (HPC).
I. Definition and Material Background of Hydrocarbon Resins
Hydrocarbon resins typically refer to polymer systems composed of carbon and hydrogen, with representative examples including polybutadiene, styrene–butadiene copolymers, and their modified derivatives. Unlike conventional epoxy resins, hydrocarbon resins contain very few polar functional groups in their molecular structure, which confers an inherent advantage when handling high‑frequency electromagnetic waves. In the development of next‑generation high‑frequency, high‑speed copper-clad laminates, hydrocarbon resins can serve not only as the primary resin but also as a modifier to optimize the dielectric properties of the resin system.
II. Analysis of the Core Advantages of the New Generation Hydrocarbon Resin
The reason why it is said that Hydrocarbon resin It is the “ideal choice” for the 6G era, primarily because it transcends the physical limits of conventional materials across multiple dimensions. Its specific advantages are as follows:
1. Exceptionally low dielectric properties: the “highway” for signal transmission
In high-frequency communications, the dielectric constant (Dk) determines the speed of signal propagation, while the dissipation factor (Df) governs the extent of signal energy attenuation. Thanks to their highly symmetrical, nonpolar molecular structure, next-generation hydrocarbon resins typically achieve Df values below 0.002, approaching levels comparable to those of PTFE (polytetrafluoroethylene). Compared with conventional epoxy resins, hydrocarbon resins can substantially reduce thermal losses during signal transmission, thereby preserving signal integrity across the terahertz frequency range. This capability constitutes a critical technological prerequisite for enabling ultra‑high‑speed data rates in 6G networks.
2. Outstanding resistance to damp heat and exceptional stability: Unfazed by harsh environments
Electronic components inevitably experience the effects of ambient humidity during operation. Water, with its extremely high dielectric constant (Dk ≈ 80), readily compromises signal integrity in high-frequency circuits. Hydrocarbon resins, lacking hydrophilic functional groups in their molecular chains, exhibit very low water absorption. Consequently, even in humid environments, copper-clad laminates manufactured from hydrocarbon resins maintain stable electrical performance. Furthermore, next-generation hydrocarbon resins, through molecular modification, have achieved a significant increase in glass transition temperature (Tg), ensuring outstanding dimensional stability under high‑temperature soldering and prolonged service conditions.

3. Excellent process compatibility: Balances performance and efficiency
Although PTFE also exhibits excellent electrical properties, its difficult processability, poor adhesion to copper foil, and high cost have limited its application in large-scale civilian markets. In contrast, the new generation… Hydrocarbon resin It exhibits superior processability. Crosslinking curing can be initiated by free radicals, making it compatible with conventional PCB manufacturing processes while enabling excellent adhesion to copper foil through formulation adjustments. This balanced combination of “high performance” and “easy processability” makes it the preferred solution for large-scale commercial applications.
4. Excellent copper foil compatibility and reliability
In high-speed transmission, the skin effect causes electrical signals to propagate primarily along the surface of the copper foil; therefore, ultra‑low profile (VLP) or extremely low profile (HVLP) copper foils are required. Thanks to their unique wettability, hydrocarbon resin systems can form strong physical and chemical bonds with these smooth copper foil surfaces. This excellent adhesion not only enhances the board’s peel strength but also improves its reliability under repeated thermal cycling, effectively preventing interlayer cracking or delamination.
III. Supporting the Strategic Status of 6G and AI Computing Power
With the advent of the 6G era, base station equipment will become increasingly dense, and antenna arrays will evolve into ultra‑large‑scale configurations. In this field, hydrocarbon resins are applied not only to base station antennas but also extend to the following key scenarios:
• Low-Earth-Orbit Satellite Communications: Satellite internet places extremely stringent demands on materials’ radiation resistance and dielectric stability under extreme temperature variations; hydrocarbon resins are ideal aerospace-grade materials.
•AI Servers and Data Centers: With the explosive growth of large AI models, the data‑transfer rates between computing chips are increasing exponentially. High‑speed copper‑clad laminates reinforced with hydrocarbon resins are essential for enabling high‑bandwidth memory (HBM) and GPU interconnects.
• Intelligent Driving Radar: Millimeter-wave radars operating at 77 GHz and higher frequencies require ultra-low-loss dielectric materials to enhance detection accuracy, and hydrocarbon resins play an irreplaceable role in this regard.
IV. Conclusion and Future Prospects
New generation Hydrocarbon resin Its development marks China’s advance into uncharted territory in the field of high-end electronic materials. It not only addresses the industry’s longstanding challenge of signal loss in high-frequency circuits but also provides a critical material foundation for green communications and high‑efficiency computing. As synthesis technologies continue to mature, future hydrocarbon resins will evolve toward lower costs, greater mechanical strength, and more environmentally friendly bio‑based formulations.
As we embark on the journey toward the 6G era, hydrocarbon resins undoubtedly serve as the unsung heroes, quietly underpinning the interconnectedness of all things and enabling ubiquitous, space‑wide communication. Through continuous technological innovation, hydrocarbon resins will continue to drive breakthroughs in CCL performance, ushering in a new chapter in the history of human communications. For companies across the industry chain—both upstream and downstream—deepening expertise in hydrocarbon resins and their application technologies is not only essential for technological advancement but also a strategic opportunity to secure a commanding position in the next decade of the electronic information industry.
