Description

TG-A4500F by T-Global Technology is a reinforced thermal gap filler pad offering a blend of high thermal conductivity (4.0W/m-K) and mechanical durability, thanks to a fiberglass mesh backing on one side. Engineered for robust thermal performance and ease of handling, this pad is ideal for environments that require consistent placement, structural integrity, and medium to high heat dissipation.

The fiberglass reinforcement provides dimensional stability, reduces stretching or tearing, and improves alignment during both manual and automated assembly. Its silicone based formulation maintains excellent surface conformity to irregular components, while also offering low thermal resistance and strong electrical insulation.

TG-A4500F is a smart solution for industrial power systems, EV control units, and rugged embedded electronics that demand reliability both thermally and mechanically.

Benefits

  • Fiberglass-Reinforced for Strength: Easy to handle, align, and install without tearing or distortion.
  • Effective Thermal Conductivity (4.0 W/m·K): Supports medium-to-high power density designs.
  • Consistent and Repeatable Performance: Ideal for scaled-up production or rework processes.
