LiPOLY EP770 is a silicone-free two-part sealing gap filler and caulking agent without low molecular siloxane volatilization. EP770 provides low viscosity and high fluidity. The high deformation material, which can be filling the gap closely, cover the tolerance, and has outstanding conductivity, makes is suitable for filling the peculiar gap.
FEATURE
- Thermal conductivity: 2.5 W/m*K
- Thermally conductive vibration dampening
- Low mixing viscosity
- Extremely low Shrinkage rate 0.01%.
- Epoxy Based material with high hardness for support
- Slow sedimentation rate due to Resin & powder mixing perfectly via superb processing technology.
- It leads EP770 material easy to mix and disperse
APPLICATION
- Motor: Torque motor, Linear Motor Servo motor
- IGBT module
- Electronic components: IC, CPU, MOS, Mother Board
- Wireless Hub
- Automotive electronics
- Between any heat-generating component and a heat sink
- 5G base station & infrastructure
- EV electric vehicle
