Overview
Jingrui (晶瑞电材) is a Chinese brand associated with electronic chemicals and semiconductor materials. Its official web presence at jingrui-chem.com presents the brand as spanning two connected tracks — chemicals and semiconductors — and as a one-stop source for tracking industry frontiers in electronic chemicals, photoresists, lithium-battery materials and functional materials. The site positions the domain itself as carrying industry recognition, able to capture chemical and new-material search traffic. The brand's product narrative is organized around four main material families. The first is electronic chemicals, described as a "war of purity": ultraclean high-purity reagents such as hydrogen peroxide, sulfuric acid and ammonia water purified to ppb level for wafer cleaning and etching; G5/G6 high-purity grades controlling metal ions and particles at ppt level; cleaning and etching functional wet chemicals with custom formulations matched to different process nodes; and high-purity solvents and auxiliaries such as NMP and isopropanol supported by analytical testing for batch consistency. The site frames electronic chemicals as the "blood" of the semiconductor industry, where each purity upgrade requires years of process accumulation, and argues that domestic substitution of ultraclean high-purity reagents is accelerating as wafer fabs and panel plants expand capacity. The second family is photoresists, called the "unsung hero of patterning." Jingrui's coverage includes semiconductor photoresists for i-line, KrF and ArF nodes, where resolution and linewidth control directly affect chip integration; panel photoresists for TFT/OLED array processes supporting large-size display panel mass production; a gradient layout from i/g-line to KrF/ArF as shorter wavelengths raise technical barriers in resins and photosensitive systems; and companion developers and strippers that ensure pattern quality and process stability. Photoresist is described as the next key bottleneck. The third family is lithium-battery materials, the "chemical foundation of new energy." This includes lithium-battery electrolytes combining high-purity solvents, lithium salts and additive formulations for conductivity, wide temperature range and interfacial film formation; functional additives such as VC and FEC that improve film formation and cycling performance and are essential in high-nickel systems; battery safety materials such as flame retardants and overcharge protection; and material recycling and regeneration that returns lithium, nickel and cobalt to the supply chain in a green closed loop. The fourth family is functional materials, a general foundation for pan-semiconductor and new-energy applications. It covers electronic-grade functional materials for chips, panels and LEDs described as a domestic breakthrough point in bottleneck segments; specialty resins and coatings for display and packaging with weather resistance and process compatibility; high-purity fillers and auxiliaries such as dispersants and wetting agents; and technical services and supply chain support under a Q/C/D/S integrated model covering quality, cost, delivery and service. Applications span wafer fabrication and packaging/testing, panel display TFT/OLED processes, LED compound semiconductors, and new energy.
History
The available evidence for Jingrui (晶瑞电材) comes from its official web presence at jingrui-chem.com, which presents the brand as operating across two connected tracks — chemicals and semiconductors — and as a one-stop source for tracking industry frontiers in electronic chemicals, photoresists, lithium-battery materials and functional materials. The site describes the domain as naturally fitting the "chemicals × semiconductors" dual track and as carrying industry recognition that can capture chemical and new-material search traffic. Within this presentation, the brand's history is told through the evolution of its material technologies rather than through dated corporate events. Electronic chemicals are described as a "war of purity," with the brand tracing a progression from G2 to G5+ high-purity grades, where metal ions and particles are controlled at the ppt level to support advanced process nodes and high-end panels. The site frames electronic chemicals as the "blood" of the semiconductor industry and notes that each purity upgrade is accompanied by years of process accumulation. It also states that, as wafer fabs and panel plants expand capacity, domestic substitution of ultraclean high-purity reagents is accelerating. Photoresists are presented as the next key bottleneck, with the brand describing a gradient layout from i/g-line to KrF/ArF. As wavelengths shorten and precision rises, the technical barriers in supporting resins and photosensitive systems also increase. The site notes that semiconductor photoresists covering i-line, KrF and ArF nodes are "under attack" (攻坚中), while panel photoresists for TFT/OLED array processes are already at scale (规模化). Lithium-battery materials are framed as the "chemical foundation of new energy," with the brand covering electrolytes, functional additives such as VC and FEC, battery safety materials, and material recycling and regeneration that returns lithium, nickel and cobalt to the supply chain. Functional materials are described as a general foundation for pan-semiconductor and new-energy applications, including electronic-grade functional materials positioned as a domestic breakthrough point in bottleneck segments, specialty resins and coatings, high-purity fillers and auxiliaries, and Q/C/D/S integrated technical services and supply chain support. All dated markers in the evidence are content timestamps of "2026.08" attached to individual product and application pages, indicating when those pages were published or updated rather than corporate milestones. The evidence does not provide founding dates, ownership changes, leadership transitions, listings, or other dated corporate events.
