OPUTE 3 W/m·K Thermal Putty for Electronic Gap Filling and Heat Dissipation
TC-30 Thermal Putty
OPUTE TC-30 is a conformable thermal gap filling material designed for heat transfer between electronic components and heat sinks. With a thermal conductivity of 3.0 ± 0.3 W/m·K, it provides close contact under low compression pressure and supports dispensing-based gap filling applications. Its moldable consistency helps fill uneven interfaces while maintaining shape stability after application.
Key Features & Benefits
- Efficient Heat Transfer: Thermal conductivity of 3.0 ± 0.3 W/m·K for electronic thermal interfaces.
- Low Compression Force: Conforms closely to electronic components under relatively low assembly pressure.
- Excellent Conformability: Fills uneven surfaces and irregular thermal interface gaps.
- Dispensable & Shape-Stable: Designed for dispensing applications while maintaining its applied shape.
- Low Volatility: ≤0.07% after 24 hours at 150°C.
- Low Oil Separation: ≤1% after 24 hours at 150°C.
- Electrical Insulation: Volume resistivity ≥3.2 × 10⁸ Ω·cm.
- Flammability Performance: V0 rating stated in the technical data sheet.
Applications
TC-30 is designed for thermal gap filling between heat-generating electronic components and heat sinks, particularly in compact electronic assemblies and dispensing processes.
- Mobile phone ICs and heat sinks
- Heat-generating electronic components
- Electronic modules and cooling structures
- Dispensed thermal gap filling applications
- Uneven surfaces requiring low compression force
Application suitability and thermal performance should be verified under actual assembly conditions.
