Two-Part Thermal Gels & Conductive Gap Fillers

When your application requires both superior thermal conductivity and long-term structural stability, our two part thermal gel is the engineered solution. This system consists of a base and catalyst that, when mixed, cure to form a soft, stress-absorbing elastomer. It is the ultimate thermal conductive gap filler, providing a fixed, reliable thermal path.

Unlike non-curing putties, our two-part thermal gel offers enhanced mechanical strength, making it ideal for demanding automotive and industrial environments. This conductive silicone gel effectively dissipates heat while providing vibration damping and structural support. As a premium thermal interface compound, it ensures a permanent, high-performance bond for the life of your device.

The Frequent FAQs of Two-Component Thermal Gel

How do your thermal gels perform under thermal cycling, vibration, and long-term aging▾

SpringGrass thermal gels: -40–150°C thermal cycling (1,000 cycles) with <5% thermal impedance change; withstand 10–2000 Hz vibration (20 g) without pump-out; 1,000 h/125°C aging shows <10% property drift.

What are the key performance differences between two-part thermal gel and traditional thermal grease or pads▾

Two‑part thermal gel typically offers lower thermal resistance (e.g., 0.05–0.2 °C·in²/W vs grease 0.1–0.3, pads 0.3–1.0), better pump‑out resistance, higher reliability under thermal cycling.

What thermal conductivity (W/m·K) ranges do your two-part thermal gels offer and how are they tested▾

SpringGrass two-part thermal gels: 1.5–6.0 W/m·K, tested per ASTM D5470 using steady-state method, controlled 50–100 psi pressure, calibrated heat flux meters, and 25°C reference temperature.
