SD-GF35
SD-GF35 is a two-component thermal interface material, cured at room or elevated temperature, featuring ultra-high thermal performance and superior softness. SD-GF35 with 3.5W/m·K thermal conductivity is a good solution for interfacing fragile components with high topography and/or stack-up tolerances to normal heat sink or housing. After cured, SD-GF35 remains a low modulus elastomer to help relieving stress during application and prevent pump-out from the interface. SD-GF35 is with lightly stickiness but not designed to be a structural adhesive.
Features and Benefits
- Thermal conductivity: 3.5 W/m·K
- Ultra-conforming, designed for fragile and low-stress applications
- Ambient and accelerated cure schedules
- Excellent low and high temperature mechanical and chemical stability
