Silicone potting & encapsulants for medical electronics

Silicone protects medical electronics and sensors with potting compounds, soft gels and encapsulants for mechanical and environmental protection, plus thermally conductive grades for heat management. Two points decide the grade: use low-volatile (controlled-volatility) silicone where outgassing would fog optics or contaminate sensors, and remember silicone is moisture-permeable — it protects and relieves stress but is not a hermetic barrier for sensitive active electronics. BIO supplies NuSil / Avantor potting, gel, encapsulant and thermal grades.

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: controlled-volatility grades where outgassing would fog optics or foul sensors.
  • Thermal: thermally conductive silicone for power/heat management; moisture permeability means pair with hermetic design for sensitive electronics.

What BIO provides

BIO provides selection, process support and supply of NuSil / Avantor potting, gel, encapsulant and thermally conductive silicone for China medical-electronics and sensor makers.

FAQ

What silicone is used to pot medical electronics?

Soft gels for stress relief, and encapsulants/potting compounds for environmental and mechanical protection; thermally conductive grades where heat must be managed.

When do I need a low-outgassing (controlled-volatility) silicone?

Whenever outgassing could fog optics or contaminate sensors/optoelectronics — controlled-volatility grades minimize volatile content for these assemblies.

Can silicone potting keep moisture out of active electronics?

It protects and relieves stress but is moisture-permeable — it is not a hermetic barrier. Sensitive active electronics should pair silicone with a hermetic design.
