Apple Rubber Products offers custom designed, EMI-Shielded O-rings and seals for a variety of electronic applications. Apple Rubber provides an alternative to metallic coating of parts and other methods utilized for EMI shielding, while delivering a reliable sealing solution
Sealing and shielding in one.
Made with conductive, particle-filled elastomers, our O-rings and seals provide high EMI shielding effectiveness in an environmental or pressure seal. The microscopic particles establish a conductive path within the elastomer to create a versatile seal for use in EMI suppression.
Particle fillers include silver, copper, nickel and graphite. Elastomers can be formulated in a range from 7 to .002
resistances in ohms centimeters.
The solution for a variety of applications. Our EMI-Shielded seals are designed to provide a conductive interface/seal for applications in a variety of industries including:
- Telecommunications
