Newma Analytics Showcase | Newma Presents Rapid Low-Field NMR Testing Technology at the 2025 National Thermal Powder Materials Innovation and Development Forum

Amid the growing demand for electronic products and high-performance computing devices, the thermal conductive materials sector is embracing new development opportunities. On 24th February, the 2025 National Forum on Innovative Development of Thermal Powder Materials (5th Edition) was successfully held in Dongguan, Guangdong.

The forum brought together numerous industry experts to discuss a range of topics, including high thermal conductivity powder materials, surface modification of thermal fillers, production processes for thermal composites, and characterisation techniques for thermal materials. The discussions focused on the technical requirements and innovation directions for high-end applications.

Application of LF-NMR Technology in Thermal Powder Materials

At the forum, the Niumag product manager presented the application of Low-Field Nuclear Magnetic Resonance (LF-NMR) technology in powder materials, explaining how the analysis of hydrogen proton relaxation times can reveal the motion state of particles. He highlighted the technology’s advantages in assessing powder dispersibility in high solid-content thermal materials—such as no sample pre-treatment, in-situ non-destructive testing, and rapid, stable results. Several application cases were shared, including lithium battery thermal slurries, ink dispersibility evaluation, and elastomer crosslink density measurement.

Following the presentation, the attending experts and scholars expressed strong interest in the innovative applications of LF-NMR technology within the powder materials field.

They noted that traditional evaluation methods often require complex sample pre-treatment and may compromise the original state of the material. LF-NMR technology, with its non-destructive, in-situ, rapid, and stable characteristics, significantly improves testing convenience and accuracy, representing a major technical breakthrough for new material development and quality control.

Inspired by the demonstration, many experts and scholars visited the Niumag booth to further explore LF-NMR technology and its potential applications across diverse fields.

Looking ahead, attendees hope to engage in deeper, face-to-face discussions with the Niumag technical team, exploring how this advanced technology can be integrated into their own research projects, collectively advancing the fields of materials science and chemical engineering.
