Thermally Conductive Insulating Film

Thermally Conductive Insulating Film

Thermal films are thin, durable materials designed to provide effective heat transfer and electrical insulation between heat-generating components and metal surfaces, such as heat sinks or housings. They are typically constructed by laminating thermally conductive silicone onto a reinforcing layer, such as fiberglass or polyimide film.

This makes them ideal for applications where tight tolerances, high voltage isolation, and clean, consistent assembly are required, especially in power electronics.

Key Features & Benefits:

• 🌡 Moderate Thermal Conductivity
  Typically ranges from 0.8 to 5.0 W/m·K, sufficient for many power devices and control units that need both heat transfer and insulation.
• 🧱 High Dielectric Strength
  Offers electrical insulation up to several kV/mm — essential for safely isolating components in high-voltage applications.
• ✂️ Thin, Rigid & Precise
  Available in very thin profiles (often under 0.5 mm), allowing tight mechanical tolerances and easy integration into compact assemblies.
• 🧲 Dimensional Stability & Mechanical Strength
  Reinforced with fiberglass or film carriers, thermal films resist tearing, wear, and deformation during assembly or long-term use.
• 🔥 UL94 V-0 Flame Retardancy
  Certified for flame resistance, making them suitable for high-safety environments.
• 🌱 Environmentally Safe
  Fully compliant with RoHS, REACH, and Halogen-Free standards.

Common Applications:

• MOSFETs & Power Transistors
• Electric Vehicle Motor Controllers
• Uninterruptible Power Supplies (UPS)
• Power Amplifiers & Inverters
• Power Supply Units (PSUs)

Choose thermally conductive films when your application requires moderate heat dissipation, strong electrical insulation, and mechanical durability in a thin, stable format. These films are ideal in high-voltage or high-safety environments, particularly where traditional pads or greases might not offer enough insulation or mechanical support.
