The UniGap 1100ES is characterized by its softness and ceramic filling. This composition makes it suitable for thermally coupling various components that dissipate heat.
It can handle a broad spectrum of stack-up tolerances. Importantly, it exerts minimal pressure forces on the component parts it interfaces with.
For applications requiring additional electrical isolation and improved resistance to cut-through, the UniGap 1100ES can be provided with a liner. This liner can be either fabric or film, applied to one side of the material.
Benefits
Flexible and moldable, it accommodates components of varying heights and dimensions using a single pad.
It includes a release liner on both faces, plus a fabric or film on one side for simpler manipulation.
Performance remains consistent across a broad temperature spectrum.
Features
- Offers good electrical isolation
- Highly soft and compliant silicone gap filler
