OPUTE 5 W/m·K Thermal Putty for Electronic Gap Filling and Heat Dissipation
TC-50 Thermal Putty
OPUTE TC-50 is a highly conformable thermal gap filling material designed to improve heat transfer between electronic components and heat sinks. With a thermal conductivity of 5.0 ± 0.3 W/m·K, it provides close thermal contact under low compression pressure and can be applied through dispensing processes. Its moldable consistency helps fill irregular gaps while maintaining shape stability after application.
Key Features & Benefits
- Efficient Heat Transfer: Thermal conductivity of 5.0 ± 0.3 W/m·K for electronic gap filling.
- Low Compression Force: Conforms to heat-generating components under relatively low assembly pressure.
- Excellent Conformability: Helps fill uneven surfaces and irregular thermal interface gaps.
- Dispensable & Shape-Stable: Supports dispensing-based application while maintaining its applied shape.
- Low Volatility: ≤0.07% after 24 hours at 150°C.
- Oil Separation: ≤2% after 24 hours at 150°C.
- Electrical Insulation: Volume resistivity ≥3.2 × 10⁸ Ω·cm and breakdown strength ≥3.0 kV/mm.
- Metal Surface Compatibility: The TDS states that the material does not cause metal surface corrosion.
Applications
TC-50 is intended for thermal gap filling between heat-generating electronic components and heat sinks, particularly in compact electronic assemblies and automated dispensing processes.
- Mobile phone ICs and heat sinks
- Heat-generating electronic components
- Compact electronic assemblies
- Automated dispensing and thermal gap filling
- Uneven interfaces requiring low compression force
Application suitability and thermal performance should be verified under actual assembly conditions.
