Introducing
METALASTIC® EXP-URE
Electrically Conductive Aircraft Antenna Gaskets
Parker Chomerics METALASTIC EXP-URE gaskets combine expanded aluminum mesh with a conformable, urethane-based filler to deliver superior corrosion resistance, electrical conductivity, and environmental sealing in flange-to-flange assemblies. Die cut to ensure consistent fit and sealing over the entire surface, these fully cured gaskets are engineered for harsh aerospace environments and are ideal for applications requiring galvanic corrosion mitigation, fluid resistance, EMI shielding, and lightning strike protection.

Unlike traditional woven mesh or particle-filled gaskets, METALASTIC EXP-URE delivers uniform, exceptional conductivity across the entire surface thanks to its expanded aluminum structure. EXP-URE achieves through conductivity at less than 15% deflection requiring only 10 psi—a fraction of the 400-600 psi (35%-40% deflection) required by competitors—enabling significantly lower torque during assembly. Significantly lower torque requirements reduces the risk of damage to aircraft structures and antennas and minimizes gel squeeze-out, ensuring reliable galvanic corrosion mitigation, lightning strike grounding, high-performance EMI shielding, and long-lasting seal integrity. 

In addition, unlike competitor products EXP-URE has no orientation requirements, which eliminates installation errors. EXP-URE is the optimal solution for engineers seeking enhanced performance, durability, and ease of installation in critical aerospace applications.
