SILCOOL TIA213G is a two-component thermally conductive silicone rubber from Momentive Performance Materials for thermal interface applications requiring excellent stress relief. Its 5,000 mPa·s mixed viscosity enables flow into narrow gaps and cures to a very soft (Shore A22) elastic rubber that relieves stress on critical electronic components.
Features & Benefits
- 1.3 W/mK thermal conductivity for effective heat transfer across interface geometries
- Very soft after cure (Shore A22) — outstanding stress relief on sensitive electronic components
- Low viscosity (5,000 mPa·s) flows into narrow gaps and complex interface shapes
- RT or heat-accelerated cure (70°C × 30 min) for process flexibility
- Non-corrosive to metal — safe for sensitive electronic contacts
- Excellent temperature resistance across the full silicone operating range
Typical Applications
- Thermal interface between components and heat spreaders
- Gap filling in consumer electronics requiring maximum stress relief
- Thermal path creation in LED assemblies and automotive electronics
- Narrow gap thermal interface in complex PCB and module designs
