Thermal conductive silicone grease, commonly known as heat dissipation paste, is a paste made from special silicone oil as the base oil, new metal oxides as fillers, and various functional additives. It is processed through specific processes and has different appearances due to different materials. It has good thermal conductivity, temperature resistance, and insulation performance, making it an ideal dielectric material for heat-resistant devices. Moreover, its performance is stable, and it will not produce corrosive gases during use and will not affect the metal in contact. High purity fillers and organic silicon ensure smooth, uniform, and high-temperature insulation of the product. Apply to the assembly surface of power devices and heat sinks to help eliminate air gaps on the contact surface, increase heat flux, reduce thermal resistance, reduce the operation temperature of power devices, improve high reliability, and extend service life. HKOPUTE1.5W/m.k thermal conductive silicone grease is a thermal conductive organic silicone like composite made from organic silicone as the main raw material, adding materials with excellent heat resistance and thermal conductivity; Suitable for application scenarios that require minimum compression thickness, constant pressure, and ease of screen printing to achieve optimal performance.
