Shielding Solutions for Electronic Applications
Apple Rubber offers custom-engineered, EMI-shielded elastomeric seals that are optimized for diverse electronic applications. Our technology provides an alternative to conventional metallic coating processes and other EMI mitigation strategies, while simultaneously ensuring robust environmental sealing.
Sealing and Shielding, All in One
Our proprietary seals are manufactured using conductive, particle-filled elastomers, providing high EMI shielding efficacy in conjunction with pressure and environmental isolation. The incorporation of microscopic conductive particles establishes a low-resistance pathway within the elastomeric matrix, resulting in a multifunctional seal for EMI suppression applications.
Conductive fillers include silver, copper, nickel, and graphite. Elastomeric formulations can be tailored to achieve bulk resistivity values ranging from 7 to 0.002 ohm-centimeters.
Versatile Solutions for Diverse Industrial Applications
Our EMI-shielded seals are engineered to provide a conductive interface and hermetic seal for applications across multiple sectors, including:
- Telecommunications infrastructure
- Military and defense systems
