Ideal for high-voltage applications.
3. Flexibility & Conformability
Maintains elasticity across a wide temperature range (-50°C to 200°C).
Fills microscopic air gaps for better thermal interface contact.
4. Chemical & Environmental Resistance
Resistant to moisture, UV radiation, and oxidation.
Performs reliably in harsh conditions.
5. Adhesion & Durability
Bonds well with metals, plastics, and ceramics.
Long-lasting performance without drying out or cracking.
