Compatherm Pad
Compatherm® Pad
Thermally conductive silicone pads.
Our pads are made using high-quality materials designed to meet the most rigorous application requirements. These soft, thermally conductive silicone pads can be used where heat needs to be conducted between a component and a heat dissipating surface, without any additional stress, or to bridge a gap for increased heat dispersion. Compatherm Pads are available in a wide range of thicknesses, mechanical properties, liner solutions and thermal performance.
Compatherm® Pad Benefits
- Excellent thermal performance
- Conformable at low pressure
- Comprehensive product range
- Cost-effective
- Customized solutions available
