FAQ for Silicone Potting Compound:

1. Q: How does the thermal performance compare to competitors?

A: A thermal conductivity of 0.5 W/M·K is considered high for condensation-cure silicones, effectively addressing most high-heat applications. We can provide real application data for reference.

2. Q: Is it electrically conductive?

A: It is completely non-conductive. Its volume resistivity is on the order of 10¹⁴ Ω·cm, making it an excellent insulator.

3. Q: How is the adhesion to aluminum substrates? Can it pass thermal shock tests?

A: This is a core strength. Its elastomeric properties and optimized adhesion formula effectively absorb CTE mismatch between aluminum and components, passing -40°C to 125°C for 1000 cycles.

4. Q: Can this be used if my product's heat sink is plastic?

A: Yes, but confirm the plastic housing (e.g., PBT, Nylon) can withstand the long-term 200°C service temperature. We recommend compatibility and temperature testing first.

5. Q: Can you customize for higher thermal conductivity?

A: Yes. We have strong R&D capability and can offer customized formulas with thermal conductivity up to 1.0 W/M·K or higher. Please contact our engineers to discuss.
