Parker Chomerics Metalastic™ EXP-URE urethane filled expanded aluminum gaskets provide an electrically conductive, fluid and pressure sealing solution for exterior mounted accessories. Developed to minimize galvanic corrosion of interfacing surfaces that require electrical bonding, these fully-cured gaskets are an effective solution in applications requiring lightning strike grounding or EMI shielding. With numerous performance improvements when compared to traditional casketing alternatives, customers can expect a 30% lower total cost of ownership from various contributing factors including the avoidance of assembly rework and material replacement.
Features and Benefits:
• Superior fluid sealing through high surface affinity urethane
• 300% reduction in corrosion when compared to traditional sealing
• Increased design freedom due to low deflection force requirements
• Optimized electrical performance at deflections as low as 15%
• Uniform distribution of fastener loads eliminates pitting and scoring
• Elimination of point-to-point contact resistance
• Gaskets come in 2 standard thicknesses (0.030 and 0.055 in)
• Available in sheets or custom steel-rule die cut gaskets
• RoHS certified
Typical Applications:
• Exterior mounted device bases (antennas, radars, lighting)
• Military access panel assemblies (electronics bays and hatches)
• Connector / waveguide assemblies
