Thermal Conductive Alumina (Spherical Alumina)
Spherical alumina, as thermally conductive filler, has the characteristics of high filling, high purity, low abrasion and high fluidity. The thermally conductive filler is specifically aimed at various applications in electronic industry and the lithium-ion battery manufacturing. The increasingly miniaturization of electronics requires materials with the capacity to distribute, transfer, and dissipate heat. For example: • In automotive electrification industry, to keep the battery from overheating during fast charging, the heat has to be conducted out of the battery stacks through the battery enclosure. So the thermal conductivity of the components forming the battery case, the gap fillers in the battery stacks are critical to the life span of the battery. • Thermal conductivity in polymers is also an important parameter for Thermal Interphase Materials (TIM) in electronic applications. TIM is any material that is inserted between two components in order to enhance the thermal coupling between them. Size available: 2.7μm, 5.9μm, 10μm, 45μm, 70μm and 90μm Application: Main application industry: electronics, LED lighting and automotive industries • Thermal conductivity filler used in EMC, CCL, etc. • Thermal interface material. • Widely used in ceramics, abrasive grain, spraying material, etc Areas with potential applications include the following: • Thermal interface materials (TIM) and heat sinks for consumer electronics and high-capacity batteries in automotive electrification. • Housings for electronic components in electric vehicles. • LEDs lighting for thermally conductive plastics/ thermoplastic materials. • Thermally conductive adhesives and greases. • Use as additive technologies to develop thermal management solutions, such as additives in polymer compounds and composite materials. • Motors, generators and transformers.
