Product Introduction

Thermal Conductive Silicone Pad

 are engineered interface materials that combine efficient thermal conductivity with excellent compressibility, making them ideal for enhancing heat dissipation and protecting electronic components.

  • High Thermal Conductivity: Effectively transfers heat from components such as chips, ICs, and power modules to heat sinks or metal enclosures.

  • Gap Filling Capability: Conforms to uneven surfaces, compresses under pressure to eliminate air gaps, and reduces thermal contact resistance.

  • Soft and Compressible: The elastic nature of the material helps absorb assembly stress and ensures consistent surface contact between interfaces.

  • Environmental Durability: Withstands a wide range of temperatures and meets flame retardancy requirements, making it suitable for long-term use in demanding electronic applications.

Feature

  • Thermal Conductivity (W/m·K): 1 ~ 15
  • Thermal Impedance (°C-in²/W, 1mm, 20psi): 0.11 ~ 1.50
  • Thickness (mm): 0.4 ~ 6.5
  • Hardness (Shore OO): 20 ~ 65
  • Continuous Operating Temperature (°C): -40 ~ 150

These are typical specifications. Actual values can be customized based on requirements. Please contact us for inquiries.
