TG-A3500 & TG-A3500F: Ultra Soft Thermal Pads from T-Global Technology
When it comes to managing heat in today’s high-performance electronics, designers turn to thermal interface materials (TIMs) that offer a reliable balance of conductivity, softness, and electrical insulation. Two standout products from T-Global Technology are the TG-A3500 Ultra Soft Thermal Pad and its fiberglass-reinforced counterpart, the TG-A3500F.
Both are part of T-Global’s widely used TG-A series of gap filler pads, designed to reduce thermal resistance between components and heat sinks. Let’s break down what makes each unique and where they shine.
TG-A3500: Soft, Compliant, and Cost-Effective
The TG-A3500 is an economical thermal gap pad engineered for mid-range applications. With a thermal conductivity of 3.5 W/m·K, it delivers efficient heat transfer while maintaining excellent compressibility. That compliance allows the material to conform to uneven surfaces, filling microscopic air gaps that would otherwise act as insulators.
-
Thermal Conductivity: 3.5 W/m·K
-
Hardness: 30 Shore 00 (extremely soft and compliant)
-
Thickness Range: 0.5 mm to 8.0 mm
-
Flammability: UL 94 V-0
-
Natural Tack: Stays in place without adhesives
The TG-A3500 is often chosen for consumer electronics, LED modules, power supplies, and telecommunication equipment, where reliable thermal performance is needed without the cost of premium-grade pads.
TG-A3500F: Reinforced for Strength and Electrical Insulation
For applications requiring added mechanical stability and insulation, TG-A3500F steps in. This material is reinforced with fiberglass backing, making it more durable during assembly and rework, while still delivering excellent thermal performance.
-
Thermal Conductivity: 3.0 W/m·K
-
Dielectric Breakdown: ≥18 kV/mm
-
Hardness: 35 Shore 00 (slightly firmer due to reinforcement)
-
Thickness Range: 0.5 mm to 11.0 mm
-
Operating Temperature: –50 °C to +180 °C
-
Flammability: UL 94 V-0
TG-A3500F is ideal for power modules, automotive electronics, and high-voltage assemblies, where both thermal and electrical insulation are mission-critical.
