In the design of industrial power supplies and EV charging modules, thermal interface materials must not only conduct heat but also provide absolute “electrical insulation” under extreme pressure. Thermal Silicone Cloth is engineered with a composite structure to balance thermal conductivity, dielectric strength, and mechanical toughness.
Chemical Principle: The Synergistic Effect of Silicone and Fiberglass The core structure of thermal silicone cloth integrates a flexible silicone matrix with a high-strength fiberglass mesh.
-
Structural Support: Fiberglass possesses exceptional tensile strength. When fastening pressure is applied by heatsinks onto power components (e.g., TO-220 packages), the fiberglass layer prevents the silicone from thinning out, maintaining a consistent dielectric barrier.
-
Molecular Infiltration: High-performance silicone fills the voids within the mesh. Active functional groups at the ends of the silicone chains create physical anchoring to the fiberglass surface, preventing delamination during high-temperature operation.
Industrial Application: Puncture Resistance and High-Voltage Isolation For components with sharp edges or applications in high-vibration environments, thermal silicone cloth offers irreplaceable advantages:
-
Puncture Resistance: The reinforcement layer effectively resists burrs or sharp component edges, preventing short circuits caused by contact between conductive components and metal heatsinks.
-
Dielectric Strength: By precisely controlling the ratio of silicone to reinforcement material, Lixing’s silicone cloth provides over 4kV of breakdown voltage protection, ensuring safety in high-voltage inverters and motor drives.
