Silicone polymer matrix filled with ceramic (aluminum oxideboron nitride) or metal oxide particlesreinforced with fiberglass or polyimide film for structural integrity.
Hardness
20-80 Shore 00
Thickness
0.5-5.0 mm
Compression Set
<20%
Dielectric Strength
>4 kV/mm
Thermal Conductivity
1.5-12 W/m·K
Operating Temperature
-40°C to 200°C
标准
ISO 22007-2ASTM D5470DIN 53479

常见问题

How does a thermal interface pad differ from thermal grease?

Thermal pads are solid, pre-formed sheets that provide consistent thickness and electrical insulation, while thermal grease is a paste that requires precise application and can pump out under thermal cycling.

What maintenance is required for thermal interface pads?

Pads typically require replacement during component servicing due to compression set degradation; they should be inspected annually in high-temperature applications.
