Product Description

Product Description

Dachuang Kehua Thermal Conductive Silicone Sheet is an advanced thermal interface material engineered to optimize heat transfer in electronic and electrical applications. Composed of a high-performance silicone matrix reinforced with metal oxides, this thermally conductive medium effectively reduces contact thermal resistance between heat-generating components and cooling systems.

Designed to bridge gaps and enhance thermal management, the silicone sheet ensures efficient heat dissipation while providing additional benefits such as electrical insulation, vibration damping, and sealing. Its versatility makes it ideal for modern compact and ultra-thin device designs, offering excellent processability and a wide range of customizable properties.
