LiPOLY EPDM30 is a silicone-free two-part liquid caulking agent that does not volatilize low-molecu- lar-weight siloxane. With high viscosity and good adhesion, it can cure quickly at room temperature or elevated temperature. With a thermal conductivity of 3.0 W/m*K, EPDM30 provides high thermal conductivity and low thermal impedance. It is ideally suited for dispensing using the dispensing robot or by syringe.
FEATURE
- Thermal conductivity: 3.0 W/m*K
- Can be applied with dispenser
- Room Temperature curing or heating curing
- Low compression stress during assembly
- Excellent adhesion to metal & PCB
APPLICATION
- Electronic components: IC, CPU, MOS, Mother Board, Wireless Hub Telecom Device, Automotive electronics, Computer , Peripherals and High frequency magnetic inductor.
- Between any heat-generating component and a heat sink.
- 5G base station & infrastructure
- EV electric vehicle
