Nordson EFD's innovative, non-silicone thermal compounds provide an ideal thermal solution by ensuring reliable heat transfer over a longer time than most industrial thermal interface materials.
Conventional, silicone-based heat sink compounds and thermal greases tend to spread after a number of heating and cooling cycles (so called pump-out), create voids and lose effectiveness, leading to over heating of electronic components and premature product failure.
Nordson EFD's non-silicone thermal compounds are formulated to virtually eliminate pump-out, ensuring long-lasting thermal management and effective heat transfer.
Features and Benefits
- Excellent heat transfer
- Good wetting
- Low bond line
- Low thermal resistance
- High thermal conductivity (high bulk thermal conductivity) for thick-film and gap-fill applications
- Non-silicone
- Does not dry out
- Resists spreading / pump-out
- Long, reliable performance
- Water cleanable for easy use and clean-up
- Optimal rheological properties for dispensing from syringe barrels with hand plungers, or more convenient, precise and consistent application of the thermal compound with Nordson EFD’s line of electro pneumatic dispensers
- High dielectric strength
- Long shelf-life stability
- RoHS and REACH compliant
- Lead-free
