LiPOLY PR28-s is a very thin, high insulator with a thickness of 0.15mm. It uses Polyimide Film as the reinforcement material, which can increase the tensile strength. It’s suitable for high power transistors, electrical equipment, and will be the best choice for auto-distribution systems.
FEATURE
- Thermal conductivity:2.5 W/m*K
- Good insulator
- Low thermal impedance
- Reworkable
- High performance
APPLICATION
- Power supplies
- Motor controls
- Power semiconductors
- 5G base station & infrastructure
- EV electric vehicle
