2-HPD-TC300 Thermal Conductive Silicone Sheet

It is a high thermal conductivity and high compression ratio polymer material silicone gasket, suitable for the electronic/electrical field with heat dissipation requirements. It is specifically designed to use gaps to transfer heat, fill gaps, and complete heat transfer between heating and cooling parts. At the same time, it also plays a role in insulation, shock absorption, sealing, etc. It can meet the design requirements of equipment miniaturization and ultra-thin design, with high processability and usability, and a wide range of thickness applications. It is an excellent thermal conductivity filling material. It has certain flexibility, excellent insulation, compressibility, and natural surface viscosity, which can meet the requirements of automated production and convenient product maintenance.

Product Features

Excellent thermal conductivity, low thermal resistance, and stable performance, reliable for long-term use; Low density products effectively reduce product weight and have a wider range of applications; Bridge the process gap in structure and reduce the process gap requirements for radiators and heat dissipation structural components; Has certain flexibility, excellent insulation, and protection against EMC; The material is soft, has good compressibility, and has shock-absorbing and sound-absorbing effects; Good resilience and convenient installation and testing for repeated use; The surface has a certain adhesive force, which can effectively adhere to IC or metal surfaces and is not easy to peel off.

Typical Applications

Between the aluminum substrate and the heat sink; Thermal conductivity between MOS tubes, transformers (or capacitors/PFC inductors) and heat sinks or enclosures; Thermal conduction and heat dissipation between the motherboard IC and the heat sink or casing; Application in the automotive electronics industry (such as xenon lamp ballasts, speakers, car series products, etc.); Between the amplifier IC, image decoder IC, and heat sink (casing); Microwave oven/air conditioner (between fan motor power IC and housing)/induction cooker (between thermistor and heat sink).
