Silicone potting & encapsulants for medical electronics
Select by assembly function, cure limits, thermal needs and qualified outgassing targets. Low-outgassing performance alone does not establish medical-grade or implant support for an exact product.
Solution essentials
- Soft gels: stress relief and vibration/shock protection for delicate boards and sensors.
- Encapsulants / potting: environmental and mechanical protection; choose hardness and cure for the assembly.
- Low outgassing: use controlled- or ultra-low-volatility families only when the assembly requires them; confirm the test method and exact-grade TML/CVCM in current data.
- Thermal and moisture: consider thermally conductive silicone where heat must be managed. Silicone is moisture-permeable and should not be described as a hermetic barrier; evaluate system-level sealing requirements.
What BIO provides
BIO helps medical-electronics and sensor teams narrow candidate grades by assembly, process and performance requirements, then confirm currently available product documentation and supply status.
Functional screening and medical or patient-contact support are separate workstreams. Confirm the exact product and finished-device requirements rather than inferring suitability from a family label.

Separate electronic performance from medical suitability
Use the controlled-volatility catalog to shortlist low-outgassing candidates, and the medical-device catalog when the exact product also needs patient-contact or medical-program support. Verify both dimensions independently.
- Assembly function and cure constraints
- Thermal, electrical and mechanical requirements
- Required outgassing method and exact-grade data
- Separate medical or patient-contact evidence, when applicable
FAQ
What silicone is used to pot medical electronics?
Soft gels can provide stress relief, while potting compounds and encapsulants can support environmental and mechanical protection; thermally conductive grades may be considered where heat must be managed.
When do I need a low-outgassing (controlled-volatility) silicone?
Use a controlled- or ultra-low-volatility family only when the assembly's outgassing requirements justify it. Confirm the required test method and the selected grade's current TML/CVCM data; the family label does not establish medical or patient-contact suitability.
Can silicone potting keep moisture out of active electronics?
Silicone is moisture-permeable and should not be described as a hermetic barrier. Evaluate system-level sealing and barrier requirements for the finished assembly where moisture ingress is critical.
