2-HPD-TC450 Thermal Conductive Silicone Pad

It is a high‑thermal‑conductivity polymer silicone pad, suitable for electronics and electrical sectors with heat‑dissipation requirements. Specially designed for heat transfer through gaps, it fills voids to realize thermal conduction between heat‑generating components and heat‑dissipating structures. Meanwhile, it delivers insulation, shock absorption and sealing performance. It meets the design demands for miniaturized and ultra‑thin equipment. Featuring excellent manufacturability and practicality with a wide applicable thickness range, it serves as an ideal thermal interface filling material.
With good flexibility, outstanding insulation and compressibility, plus natural surface tackiness, it supports automated production and facilitates product maintenance.

Product Features

Excellent thermal conductivity, low thermal resistance, and stable performance, reliable for long-term use; 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).
