Features Of Dow DOWSIL TC-4016 Silicone Rubber

  1. High thermal conductivity (1.6 W/m·K) for efficient heat dissipation in demanding electronic environments.

  2. Excellent electrical insulation properties with high dielectric strength and volume resistivity.

  3. Low modulus and high conformability enable stress relief and reliable interface contact on uneven surfaces.

  4. Thermally stable silicone elastomer formulation, operating continuously from –50 °C to 200 °C.

  5. Ready-to-use two-part addition-cure system with low mixed viscosity and extended pot life for automated dispensing.

Typical Applications Of Dow DOWSIL TC-4016 Silicone Rubber

  1. Thermal interface material (TIM) between power semiconductors and heat sinks in EV inverters and onboard chargers.

  2. Die-attach and underfill encapsulation for high-power LED modules requiring long-term thermal cycling reliability.

  3. Gap-filling pads and form-in-place (FIP) gaskets for battery management systems (BMS) and DC-DC converters.

  4. Thermal management solutions in renewable energy power electronics, including solar inverters and wind turbine controllers.
