--- Unmatched Thermal Conductivity ---
• Exceptional Heat Dissipation Performance:
In a real-world application with a leading Chinese electric vehicle (EV) battery manufacturer, Jiangsu Xinhetong's spherical boron nitride was integrated into the thermal paste used in high-density power modules. The client faced persistent overheating issues during rapid charging cycles, which threatened battery longevity and safety. After switching to Xinhetong’s premium-grade spherical boron nitride (45–60 W/(m·K)), thermal resistance dropped by 38% compared to conventional fillers. This improvement enabled the EV manufacturer to extend its fast-charging cycle life by over 25%, significantly enhancing customer satisfaction and reducing warranty claims. The case study was later featured in the 2023 China Energy Storage Conference. Furthermore, in collaboration with a major aerospace electronics supplier, Xinhetong’s spherical boron nitride was used in satellite control units operating in extreme temperature environments. The material maintained stable thermal performance across -55°C to +125°C, proving its reliability under harsh space conditions. These results underscore Xinhetong’s ability to deliver not just high thermal conductivity, but consistent, real-world performance where failure is not an option.
--- Superior Purity and Quality Control ---
• Ultra-Low Impurity Content:
Jiangsu Xinhetong maintains a purity level exceeding 99.8% in its spherical alumina and boron nitride products, rigorously controlling trace impurities such as iron (Fe < 10 ppm), silicon (Si < 5 ppm), and calcium (Ca < 3 ppm). This precision is not theoretical—it has been validated through independent lab testing by TÜV Rheinland and SGS. A notable example involves a global medical device company developing a next-generation MRI cooling system. Due to the risk of electromagnetic interference and insulation degradation from impurities, the client required a filler with near-zero metallic contaminants. Xinhetong’s ultra-pure spherical boron nitride passed all biocompatibility and dielectric strength tests, enabling the device to achieve FDA Class II certification. In another instance, a semiconductor packaging firm reported a 40% reduction in field failures after replacing their standard filler with Xinhetong’s high-purity product. The root cause analysis revealed that residual iron particles had previously caused micro-short circuits in high-frequency chips. By eliminating these contaminants, Xinhetong helped the client improve yield rates from 87% to 96%. These cases demonstrate how our stringent quality control isn’t just a claim—it’s a proven differentiator in mission-critical applications.
• Safe for Sensitive Applications:
The safety profile of Xinhetong’s spherical boron nitride is especially crucial in industries where component failure can lead to catastrophic outcomes. One compelling example comes from a Tier-1 automotive supplier integrating our material into the thermal interface layers of advanced driver-assistance systems (ADAS). During accelerated aging tests simulating 10 years of operation, the ADAS unit using Xinhetong’s filler showed no signs of delamination, corrosion, or electrical leakage—unlike units using lower-purity alternatives that developed micro-cracks due to ionic migration. Additionally, a Japanese robotics manufacturer used Xinhetong’s spherical boron nitride in the control boards of surgical robots. The material’s inert nature and lack of volatile byproducts ensured zero contamination in sterile environments, meeting ISO 13485 and JIS B 2151 standards. Even in high-humidity and high-voltage conditions, the material remained stable. These real-world validations have led to long-term contracts with multiple Fortune 500 clients in healthcare, defense, and autonomous systems. At Jiangsu Xinhetong, we don’t just produce materials—we build trust through transparency, traceability, and uncompromising safety.
--- Comprehensive Product Range ---
• Tailored Solutions for Diverse Industries:
Jiangsu Xinhetong offers three distinct series of spherical boron nitride—Standard Purity (99.5%), High Purity (99.8%), and Ultra-Purity (99.9%)—each engineered for specific industrial demands. A prime example is a collaboration with a U.S.-based consumer electronics giant launching a new generation of gaming laptops. The company needed a balance between cost and performance for mass-market models. Xinhetong’s Standard Purity Series delivered 40–45 W/(m·K) thermal conductivity at a competitive price point, enabling the laptop to maintain CPU temperatures 12°C lower under sustained load. Meanwhile, for the flagship model targeting professional users, the High Purity Series (50–60 W/(m·K)) was deployed, allowing for thinner heat spreaders and quieter fan operation. In the aerospace sector, a European satellite manufacturer adopted our Ultra-Purity Series for onboard processors exposed to cosmic radiation. The material’s structural stability and low outgassing rate made it ideal for vacuum environments. Over 18 months of on-orbit testing, no thermal degradation was observed. Beyond electronics, Xinhetong also supplied spherical boron nitride to a renewable energy startup developing high-efficiency solar inverters. The material improved heat transfer efficiency by 22%, contributing to a 15% increase in system uptime. These diverse success stories highlight Xinhetong’s flexibility, scalability, and deep technical support—from prototyping to full-scale production. Our team works closely with clients to customize particle size, morphology, and surface treatment, ensuring seamless integration into existing manufacturing processes.
