Features Of Dow DOWSIL TC-4015 Silicone Rubber

  1. High thermal conductivity (1.5 W/m·K) for efficient heat dissipation in electronic assemblies.

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

  3. Low modulus and high conformability, enabling stress-free bonding of sensitive components.

  4. Room-temperature vulcanizing (RTV) silicone rubber with one-part, moisture-cure chemistry.

  5. UL 94 V-0 rated flame retardancy for enhanced safety in demanding applications.

Typical Applications Of Dow DOWSIL TC-4015 Silicone Rubber

  1. Thermal interface material (TIM) between power electronics and heat sinks.

  2. Encapsulation and potting of LED drivers and power converters.

  3. Gap-filling adhesive for battery module thermal management systems.

  4. Die-attach and underfill in automotive ADAS and infotainment control units.

  5. Thermally conductive bonding layer in 5G base station RF power amplifiers.
