Power Systems
Aircraft and spacecraft power systems generate, store, distribute, and convert electrical power under continuous vibration, wide temperature swings, and strict weight constraints. From aviation solar panels to battery packs, power distribution harnesses, and power semiconductor modules, these systems depend on materials that hold up structurally and electrically over the life of the platform.
Krayden supplies encapsulants, potting compounds, die attach materials, and insulating tapes used across solar panel, battery and energy storage, power distribution, and power semiconductor applications in aerospace and defense.
Where Materials Are Used in Power Systems
Encapsulant and bonding materials used in the lamination and assembly of aviation solar panels.
Potting compounds, structural adhesives, and sealants used to bond cells, seal enclosures, and provide electrical insulation within battery packs.
Polyimide and polyester insulating tapes and structural adhesives used across power distribution harnesses and connector assemblies.
Die attach materials and potting compounds used to assemble and protect power semiconductor modules and converters.
Key Aerospace Requirements
Reliable electrical insulation between conductors and grounded structure, sized to the actual voltage and clearance in the assembly.
Mechanical durability under continuous vibration, particularly at cell interconnects, potted joints, and wiring terminations.
Stable performance across wide operating ranges, from cold-soak conditions to elevated temperatures near power-generating components.
Resistance to moisture, humidity, and contaminants at enclosure seams, connector interfaces, and battery pack housings.
Low-outgassing formulations for satellite and space-exposed power hardware, where vapor deposition on optics or sensors is a concern.
Frequently Asked Questions
Where can I find material information for aviation solar panels?
See the dedicated Aviation Solar Panel page for encapsulant, bonding, and interconnection materials specific to solar panel lamination and assembly.
Why does battery pack potting need to provide both structural and dielectric function?
Battery packs combine closely spaced cells at meaningful voltage with continuous vibration exposure. A potting compound that only bonds mechanically but lacks adequate dielectric strength can allow arcing or short circuits between cells or to the enclosure, so both properties are typically selection-critical rather than optional.
What is the difference between an insulating tape and a structural bonding adhesive in power distribution assemblies?
Polyimide and polyester insulating tapes are selected for dielectric strength, temperature resistance, and wrap or masking behavior around conductors, and generally carry no structural load. Structural adhesives, by contrast, are selected for bonded joint strength and are used to secure connectors, brackets, and harness routing hardware rather than to insulate a conductor.
Why is die attach material selection important for power semiconductor modules?
Die attach in a power module secures the semiconductor die, provides the primary path for heat and, in most conductive configurations, electrical grounding. Because power devices generate significant heat during operation, the die attach material's thermal and electrical conductivity, cure conditions, and reliability under thermal cycling are typically critical selection factors rather than secondary ones.
Are these materials qualified to aerospace or space standards?
Qualification varies by product, chemistry, and grade. Some materials in this category are formulated to meet outgassing or environmental standards commonly referenced in aerospace and space hardware, but current certification status should be confirmed for the specific product and grade in question. Contact the technical team for documentation.
Do you provide support for power system material selection?
Yes. The Krayden technical team works directly with engineers on material selection, datasheets, and application support for solar, battery, power distribution, and power electronics assemblies.
Need Help Selecting Power System Materials?
Selection depends on the voltage, environmental exposure, mechanical duty cycle, and any applicable certification requirements. The Krayden technical team provides material selection support, datasheets, and application guidance across solar, battery, power distribution, and power electronics materials.
