10” Polyamide Spheres Overview

Deck Purge Box
These 10” Dia hollow polyamide spheres are made from PA15 nylon. Each sphere is made from two injection-molded hemispheres, providing uniform shape, wall thickness and density. The IFS-141 Instrument Housings are held together by partial vacuum-sealed with an o-ring face seal, while the IFS-142 Flotation spheres are thermally fused together.  They are designed to withstand heavy blows and high pressure. Spheres are rated to 1,000 meters.
 
The polyamide can be drilled, tapped, spotfaced, solvent or adhesive bonded, thermally welded, or embossed.  Like glass, it’s corrosion proof and invisible to WiFi, but more shock resistant.  Polyamide can be degraded by long-term exposure to UV, and certain organic solvents.

Designer’s Note: Buoyancy of an instrument sphere is reduced by the air weight of the contents placed in the interior.
