Thread Content

Recently, Smart High Tech officially announced the successful development and launch of a new type of graphene-enhanced thermal interface material (TIM). With its excellent thermal conductivity, this product fills another gap in the company’s portfolio of high-end thermal management materials, offering a new option for cooling solutions in high-performance electronic devices. It is reported that this new product, named GT-300, has a measured thermal conductivity of over 300 W/mK, demonstrating an extremely high heat conduction capacity. Meanwhile, at a thickness of 300 microns and an applied pressure of 0.28 bar (approximately 0.028 MPa), its thermal contact resistance is as low as about 2 K·mm²/W. This key technical parameter indicates that the performance of this graphene-reinforced TIM material is on par with that of liquid metal cooling interfaces. Compared to liquid metal cooling solutions, GT-300 also boasts two notable advantages: high aging resistance and corrosion resistance. These properties enable it to be used in various applications that require high functional stability and a long service life, thereby expanding its range of applicable scenarios. As an important addition to Smart High-Tech’s existing graphene TIM solutions in the GT-200 series, the introduction of GT-300 has enhanced the company’s product portfolio in the field of thermal interface materials. Currently, the efficient heat transfer from heat-generating components to heat sinks or cooling plates has become a key bottleneck limiting the operating temperatures of high-performance electronic devices. The excellent heat conduction capabilities of GT-300 enable a reduction in the cooling requirements of subsequent system solutions, such as data centers, thereby helping to lower energy consumption and operational costs in such applications. In the completed practical tests, the GT-300 demonstrated excellent performance in real-world applications: when the chip’s output power reached 1000 W, the temperature of the radiator using the GT-300 was significantly lower compared to similar reference products, highlighting its superior heat dissipation efficiency. Regarding the product promotion plan, Smart High-Tech has made it clear that it will prioritize introducing the GT-300 alongside the existing GT-200 series products into consumer applications, in order to gather market feedback and improve the product experience. Subsequently, the focus of promotion will gradually shift to industrial and commercial applications, thereby achieving coverage across all sectors. The introduction of the GT-300 not only demonstrates Smart High-Tech’s technical expertise in the application of graphene materials; its performance comparable to that of liquid metals, along with its improved stability, will also provide significant support for improving heat management in high-performance electronic devices and AI computing equipment, thereby helping to drive these industries toward greater efficiency, energy savings, and longer operational life. Smart High Tech is a company dedicated to producing new cooling materials enhanced with graphene, focusing on the development of cooling solutions for CPUs, GPUs, chipsets, and other high-heat electronic devices. This is crucial for developing smaller, faster, lighter, and more feature-rich high-performance electronic products in a sustainable manner. Provide expertise in high-performance graphene-reinforced materials and related manufacturing processes. One of the unique and innovative development examples is graphene-enhanced \"thermal interface materials\", known as TIMs, which are used for cooling electronic and power modules and can conduct heat efficiently both vertically and horizontally. TIM belongs to our GT-TIM® product series, which features various versions and different functions. Through the partnership with Henkel’s Loctite brand, products are sold to internationally leading electronics-intensive companies in the BTB sector, while products are also sold through Thermal Grizzly’s Kryosheet brand in the BTC business. Smart High Tech was founded in 2003 by Dr. Johan Liu, a professor at Chalmers University of Technology in Sweden. Since its establishment, the company has carried out pioneering research that has laid a solid foundation for product development, enabling the company to continue growing and expanding. Innovation has been at the core of the company since its inception; therefore, Smart High Tech has also participated in various EU and **innovation projects. Smart High Tech also has another subsidiary: Ruixi New Materials High Technology Co., Ltd., located in Shanghai, China, which is responsible for mass production. In addition, Smart High Tech has its own production facility for graphene-enhanced thermal interface materials in Sweden. In the fall of 2021, Smart High Tech conducted its initial public offering (IPO) with a focus on the stock market. At the same time, a issuance worth 22 million Swedish kronor, equivalent to around 2.2 million euros, was carried out to further strengthen Sweden’s production facilities and expand its sales and marketing teams. In June 2024, Smart High Tech raised another 90 million kroner to expand its production capacity and further internationalize its operations. In December 2024, Smart High Tech raised another 110 million kroner to further expand, with the goal of becoming a qualified mass supplier as soon as possible.
