eSEAL™ EPFOAM(Electrically Plated Foam Seal)

NYS-SEALOR E-coating conductive rubber is a high-performance composite product formed by non-conductive elastomer as the carrier and coated with conductive metal particles. The good elasticity of the internal non-conductive elastomer ensures the excellent toughness of the product, which is convenient for product assembly and can achieve environmental sealing at the same time to prevent water or other dust from entering the inside of the device. E-Coating conductive rubber combines the high shielding characteristics of the conductive layer with the advantages of the mechanical properties of non-conductive elastomers. It is a patented product of Leizdun Technology with independent intellectual property rights.

eSEAL™ EP(Electrically Plated Seal) gasket is a unique product of a non-conductive silicon foam core with its skin coated with conductive layer. This structure ensure a good elasticity of its core, which can achieve both environmental sealing and easily assembly, at the same time it will also offer excellent EMI shielding  properties for various applications.

Product Description

Features and advantages

  • The elastic inner core has no metal fillers and has the most optimized compression and aging characteristics
  • The conductive layer material is evenly coated in the outer film and has excellent conductivity characteristics 
  • Through a special coating process, the conductivity and shielding are not reduced In the case of performance, the cost of precious metals is effectively saved.
  • Compared with the fully-filled elastomer, the attenuation performance under full compression is not reduced. 
  • Very low compression and deformation resistance. 
  • A variety of conductive layer materials are available
