Urethane Filled Expanded Aluminum Gasketing
Parker Chomerics has engineered urethane-filled expanded aluminum gaskets, offering a pliant, electrically conductive, fluid, and pressure-sealing solution suitable for diverse flange-to-flange assemblies. These gaskets are designed to mitigate galvanic corrosion between interfacing surfaces necessitating electrical bonding. They are fully cured and prove highly effective in scenarios demanding lightning strike grounding or EMI shielding. Compared to conventional gaskets, they deliver several performance enhancements, leading to an estimated 30% reduction in total cost of ownership. This reduction stems from factors such as decreased need for assembly rework and material replacement.
PRODUCT FEATURES:
- Conformable, high surface affinity urethane provides superior fluid sealing.
- Superior fluid sealing results in corrosion reductions up to 300% when compared to traditional sealing alternatives, resulting in rework cost reductions of up to 50%.
- Soft urethane requires low deflective forces.
- Low deflective forces allow for increased design freedom for the interfacing assembly, resulting in cost optimization through reductions in fastener quantities, flange thickness, assembly tolerances and weight.
- Wave-formed aluminum provides electrical continuity at gasket deflection as low as 15%.
- Electrical continuity at gasket deflection as low as 15% promotes full surface electrical contact between gasketing and mating surfaces in highly variable applications where deflection is commonly localized around fasteners. This promotes optimized electrical performance and minimized system failures and associated rework cost.
- Expanded aluminum promotes uniform distribution of fastener loads.
- Uniform distribution of fastener loads eliminates harmful pitting and scoring commonly found with woven-wire based gasketing solutions due to point-stress created by wire overlap locations. Lower stress concentrations reduce the associated rework costs of flange cracking due to stress fatigue.
- Expanded aluminum promotes optimized electrical performance.
- Optimized electrical performance is gained through the elimination of point-to-point contact resistance associated with woven wire gasketing technologies. Improved electrical efficiency promotes minimized system failures and resulting rework costs.
IDEAL APPLICATIONS:
- Exterior mounted device bases (antennas, radars, lighting, etc.)
- Access panel assemblies (electronics bays and hatches)
- Connector/waveguide assemblies
