Parker Chomerics CHO-SEAL® reinforced conductive and non-conductive elastomer seals consist of a corrosion-resistant CHO-SEAL conductive or non-conductive elastomer base, reinforced with a woven or knitted fabric material, or wire mesh. These seals are can be used in airframe shielding applications or any other applications requiring a reinforced seal. The integrally molded reinforced material provides improved mechanical properties, while maintaining the electrical properties of the conductive elastomer base materials. CHO-SEAL reinforced seals are used to provide EMI shielding, lightning protection, high intensity radiated fields (HIRF) protection and radar cross section reduction by maintaining surface electrical continuity at joints, seams and openings in air frames.
CHO-SEAL® 1285, 6502, 1287, 1298 and 6503 are typically used for the conductive elastomer base material.
Knitted Dacron fabrics are used as reinforcing layers to dramatically increase the tensile and tear strength of the elastomer without adding weight to the seal. If applicable, layers of aluminum or wire mesh are used to provide high current• carrying capability required for lightning strike protection. Other reinforcing materials are available to provide resistance to flame.
Features/Benefits:
• Dramatically increased strength without added weight
• Ability to have high current carrying capability for lightning strike protection
• Optional flammability resistance
Typical Applications:
• Electronic bay doors
• Wing panel access covers
• Engine pylons
• Radomes and nacelle seals.
Parker Chomerics can design and develop reinforced custom cross sections, shapes and sheets to meet specific customer requirements.
