It is fire resistant, self-extinguishing, and may be approved for explosion proof applications by UL and other certifying organizations. Viscosity permits penetration of small cavities. Product bonds to aluminum, steel, and copper alloys, enabling non-elastomeric sealing designs. Applications include feedthrus for HVAC compressors, pumps, autoclaves, and solder reflow ovens.
Original Press Release:
New Development in Feedthru Technology Incorporates High Temperature Ceramic Potting Compound to Seal Connectors, Wires, Cables, and Fiber Optics for Applications Up to 500° F
ROCKAWAY, NJ - March 1, 2003 - Douglas Electrical Components, an industry leader in providing a unique line of hermetically sealed conductors, has introduced a new ceramic potting compound which offers a breakthrough in sealing technology for applications up to 500° F. High-temperature applications for the ceramic-filled compound include feedthrus for HVAC compressors, pumps, autoclaves, solder re-flow ovens, semiconductor processing equipment, and others. The compound can be applied to high-pressure service and weld-in design. In most customer applications, the compound allows flexibility in design for feedthrus at these high temperatures.
The compound demonstrates excellent electrical, mechanical, and chemical resistance properties. It is also fire resistant, self-extinguishing, and may be approved for explosion proof applications by UL or other certifying organizations. Its viscosity permits penetration of small cavities for design flexibility and it bonds well to aluminum, steel and copper alloys, enabling non-elastomeric sealing designs.
Douglas Electrical Components provides hermetically sealed connectors and feedthrus and can hermetically seal any conductor through any housing, including wires, cables, harnesses, and fiber optics. The company also supplies turnkey sub-assemblies,
including contacts, connectors and other components. These can be
fully customized.
