Thermal conductive silicone for LED driver and electric parts use
Two component type Silicone was performed Excellent electrical properties and High thermal conductivity,exclusively used in LED driver, IC chips, CPU & VLSI and other electric parts to transfer the internal heat to outside region.
Especially, TR-7123 is suitable for high temperature for a long term operation.
The main feature was list as follow
1. Excellent electrical properties
1. High thermal conductivity
2. High temperature working condition
3. Chemical stability
4. Easy performance
5. Pass new environmental standard
