Thermal Gap Filler Liquid Dispensed Pad
Back to Thermal Management Silicones
Momentive’s thermally conductive gap fillers are non-slumping, dispensable materials that can be applied to gaps to create a heat path. These non-adhesive curing type TIMs form a soft, stress-absorbing thermal interface. In addition to filling gaps in electronic components, they can be applied to flat or high-profile 3-dimentional surfaces as a cure-in-place thermal pad or as a pump-out resistant alternative to greases.
Key Features of Momentive's Thermal Gap Fillers
- Good thermal conductivity
- Fast, low temperature cure
- Helps provide stress relief during thermal cycling
- Conforms to complex, 3-dimensional designs
- Non-adhesive, repairable
