LiPOLY AT920-s is an unsupported thermally conductive tape with a thermal conductivity of 3.5 W/m*K. The thickness comes in 0.25 and 0.50 mm, and the AT920-s can withstand 4~7K voltage. Using highly thermal conductive particles makes the tape extremely reliable and easy to use. The stickiness and strength will increase when temperature and pressure rise.
FEATURE
- Thermal conductivity:3.5 W/m*K
- Excellent adhesive properties
- Designed for manufacture
- Excellent long term reliability
APPLICATION
- Automotive electronics
- Telecommunications
- LED light bar & LED lamp
- Between any heat-generating component and heat sink
- 5G base station & infrastructure
- EV electric vehicle
