Searching from applications: Characteristic of SiC

As a highly thermal-conductive filler and radiating filler material

In recent years, semiconductor devices and electronic devices for LEDs are getting smaller and smaller, moving toward high-density integration. As a result, thermal management will become a problem and highly thermal-conductive filler will be needed in the fields of thermal grease, thermal sheets and more. Our product has highly thermal-conductive and radiating performance, and is a very stable, safe material. We have an assortment of high-performance spherical SiC products, and we’ll continue pursuing the unlimited possibility of SiC.
