Silicone Potting Compound for Portable CT Scanning

Portable CT Scanning Background

In emergency medicine, speed is critical. For stroke victims, an early diagnosis can be the difference between a full recovery and permanent brain damage. Computerized Tomography (CT) scans are essential for this diagnosis, but their size and cost have traditionally limited their use to hospitals. The development of portable CT scanners marks a revolutionary step in bringing life-saving diagnostics to the patient, wherever they are.

Prostech is proud to have played a crucial role in this innovation by providing a critical material solution to a leading medical device manufacturer.

The Challenge: Overcoming Heat in a Compact Design

A manufacturer developing a groundbreaking portable CT scanner faced a significant engineering hurdle. A key challenge in reducing the size of any electronic device is managing the heat generated by its components. In this case, the high-voltage power supply, a core component of the scanner, was the source of the problem.

To protect the power supply from dielectric breakdown and overheating, it was potted (encapsulated) in an epoxy compound. However, as the manufacturer tried to shrink the power supply’s design, the increased heat concentration caused the epoxy to crack. This failure put the entire portable scanner project at risk.

The Solution: Silicone Potting Compound for Portable CT Scanning and Automation Systems

Silicone Potting Materials for Portable CT Scanning: Insulcast RTVS 27

The manufacturer’s design engineers turned to Prostech for a material that could withstand the demanding environment of a compact, high-voltage power supply. Our technical team analyzed the thermal and electrical requirements and recommended Insulcast RTVS 27, a room-temperature vulcanizing (RTV) silicone compound from our trusted partner, ITW Performance Polymers.

INSULCAST RTVS 27 RTV Silicone ITW Performance Polymers

Insulcast RTVS 27 was the perfect potting compound for Portable CT Scanning solutions because of its superior properties:

• Exceptional Heat Dissipation: It effectively transfers heat away from critical components, preventing overheating and failure.
• High Dielectric Strength: It provides robust electrical insulation, superior to the previous epoxy.
• Low Viscosity & Flexibility: The material flows easily into complex geometries during manufacturing and remains flexible after curing, preventing cracks caused by thermal expansion.
• Superior Adhesion: It creates a strong bond that prevents tracking and corona discharge, ensuring the long-term reliability of the power supply.
• Safety Compliant: Insulcast RTVS 27 is fully REACH/ROHS Compliant.

The Outcome: Enabling a New Generation of Life-Saving Technology

By switching to Silicone Potting Compound for Portable CT Scanning, the manufacturer successfully solved the critical overheating issue. This breakthrough not only enabled the launch of their innovative portable CT scanner but also gave them the confidence to develop an entire new line of compact, high-voltage power supplies.

Thanks to this collaboration, a more accessible and mobile diagnostic tool is now available, helping to save the lives of stroke victims.
