Orient Precision to Accelerate Electric Vehicle Thermal Management Materials Business

Orient Precision, a company specializing in electrification components, is set to ramp up its electric vehicle (EV) thermal management materials business.

On September 1, Orient Precision announced that it has completed the development of a prototype for a high-performance magnesium oxide (MgO)-based gap filler and has begun application testing.

A gap filler is a thermal interface material (TIM) that fills microscopic gaps between components to effectively transfer and dissipate heat produced by EV battery packs and power electronics components. As EVs demand higher power output and performance, along with larger battery capacities, efficient thermal management is becoming increasingly important for vehicle performance, safety, and battery lifespan.

Magnesium oxide is gaining attention as a next-generation heat dissipation material due to its high thermal conductivity and electrical insulating properties. Its potential is particularly anticipated in the EV sector, where high-performance thermal management and lightweight design are required simultaneously. However, there are technical challenges to address, such as sensitivity to moisture, cost, and material processing and compounding issues. Therefore, developing technologies for stable control of material properties is crucial for practical product applications. Since 2022, Orient Precision has been continuously developing heat dissipation materials using high-performance magnesium oxide through collaborative research projects to solve these technical challenges.

Recently, by applying powder surface modification technology, the company has optimized magnesium oxide particles and completed the production of a gap filler prototype. In particular, by optimizing particle size, shape, and blending ratios, Orient Precision has developed products with a maximum thermal conductivity of up to 12 watts per meter kelvin (W/m·K), thereby establishing a manufacturing foundation capable of meeting diverse customer performance demands.

Following the prototype development, Orient Precision plans to conduct performance and reliability verifications under real-world application conditions. The company aims to enhance the completeness of its products by comprehensively evaluating not only thermal conductivity but also insulating properties, durability, and other qualities required for automotive components.

A representative from Orient Precision stated, "With the rising trend of higher output and enhanced performance in the EV market, thermal management for batteries and power electronics components is becoming a critical factor for both vehicle performance and safety," and added, "Through the development of the magnesium oxide gap filler prototype, we will continue to secure technological competitiveness in the thermal management materials business."
