Tflex B200: A Versatile Thermal Gap Filler for Modern Electronics

When designing cutting-edge electronics—from EV battery packs to aerospace avionics and high-performance computing—managing heat effectively is mission-critical. That’s where Tflex B200 shines: a compliant thermal gap filler engineered to bridge the interface between heat-generating components and their thermal dissipation structures.

Key Highlights

  • Thermal Conductivity: 2.0 W/m·K (ASTM D5470)

  • Material Construction: Ceramic-filled thermal silicone sheet, naturally tacky on both sides—no adhesive required

  • Mechanical Compliance: Soft, low-modulus material conforms to surfaces, reducing mechanical stress and improving long-term reliability

  • Shock & Dielectric Protection: Excellent at absorbing shock in demanding environments and offers high dielectric breakdown protection (“high DBV”)

Thickness & Sizes

Available in thicknesses from approximately 1 mm to 5 mm in 0.25 mm increments; standard sheet sizes include 9″ × 9″ and 18″ × 18″—with custom die-cut options also available.


FG vs. MFG: Reinforcement Options Explained

Tflex B200 isn’t a one-size-fits-all solution—its FG and MFG variants provide added strength and application-specific flexibility:

Tflex B200MFG (Middle-Fiberglass-Reinforced)

  • Features a fiberglass layer embedded in the mid-section.

  • Retains tackiness on both sides, facilitating stable placement during both manual and automated assembly.

  • Enhances tensile strength, minimizing deformation—especially helpful during handling or in high-vibration environments.

  • Ideal for applications that require mechanical robustness without compromising assembly flexibility.

Tflex B200FG (One-Sided Fiberglass-Reinforced)

  • Includes fiberglass reinforcement positioned near one surface.

  • Offers higher deflection compared to MFG, meaning it resists breakthrough or compression more effectively on that reinforced side.

  • Best suited for scenarios where one surface is more fragile or requires extra protective reinforcement—like delicate chips or uneven heatsink surfaces.


Why Tflex B200 Stands Out

Feature Benefit
2.0 W/m·K Thermal Conductivity Delivers reliable thermal transfer across gaps in demanding designs
Compliant Silicone Construction Aids stress relief and maintains intimate contact across uneven surfaces
Fiberglass Options (FG / MFG) Adds customizable mechanical reinforcement tailored to your assembly needs
Tacky Surface Finish Ensures secure placement without additional adhesives
Broad Applications Effective across automotive, telecom, aerospace, consumer electronics, and more

Final Thoughts on TFLEX B200/More Information

Whether you’re building robust EV battery packs that must withstand vibration or designing compact consumer electronics where every micron and contact point matters, Tflex B200 offers a blend of thermal performance, mechanical adaptability, and ease-of-use. Its FG and MFG variants provide the flexibility to choose the protection level that best suits your application’s unique stress points and manufacturing methods.
