Medical Diagnostics Devices

Stockwell Elastomerics provides many components to the medical diagnostics devices industry, including:

• Compression molded silicone gaskets
• Injection molded liquid silicone rubber components
• Fabricated gaskets
• Solid silicone gaskets
• PORON® gaskets
• Silicone plenum gaskets
• Electrically conductive components
• EMI shielding gaskets
• Semi-conductive carbon-filled silicone rubber gaskets and pads
• Neoprene gaskets and pads
• Silicone sealing gaskets

These uses often require gaskets or pads with special properties for resiliance, longevity, and inertness or that meet special requirements for electrical conductivity, ESD protection and EMI shielding.

Specialty Materials for Medical Applications

Stockwell Elastomerics has worked closely with leading suppliers of silicone rubber to develop specialty materials engineered to meet the strict demands of medical applications. One example would be SSP4749 which is a unique high consistency rubber (HCR) that is platinum catalyzed. This platinum-cured silicone is an excellent choice for medical device (non-implant) applications meeting USP Class VI, food contact applications that need to meet FDA CFR 21 177.2600 and other applications that may have sensitivities to outgassing or leaching. SSP4749 is available for molding, sheet stock, and fabricated parts in durometers ranging from 10 up to 70 Shore A durometer.

Custom Molded Silicone

Stockwell Elastomerics’ core products for the medical diagnostics industry are compression molded silicone gaskets and injection molded liquid silicone rubber components with high performance flexing capabilities for mechanical requirements inside the device. Silicone rubber has gained broad acceptance in the medical equipment industry for its combined properties of resilience, age resistance and general inertness.

Fabricated Gaskets and Cushioning Pads

Medical diagnostic devices often require specialty foam gaskets for displays and dust filters. Liquid silicone rubber is available in sheets for fabricated solid gaskets, silicone foam gaskets and cushioning pads. Silicone foam meets the UL 94V-0 flame rating.

PORON® cellular urethane and silicone foam sound and vibration cushioning pads are frequently specified to reduce noise in equipment designed for use near the patient.

Electrically Conductive Components

Similar to other electro-mechanical products, medical diagnostic devices often have requirements for EMI shielding gaskets to reduce emissions from devices and protect against interference from other units in hospital environments. Semi-conductive carbon-filled silicone rubber and neoprene gaskets and pads are available for ESD grounding needs.

Stockwell Elastomerics’ Scope of Applications in Medical Equipment

Stockwell Elastomerics’ focus in the medical equipment industry is limited to the mechanical requirements of the device. Stockwell Elastomerics does not provide components for implantation or in-body applications.
