eSEAL™ EC series

eSEAL™ EC series electrically conductive silicon rubber has an excellent conductivity, and very good mechanical flexibility. Its application includes not only meeting grounding and EMI shielding requirement, but also achieve critical environmental sealing requirement. Conductive particles include silver-plated aluminum, silver-plated glass, silver-plated nickel, silver-plated copper, nickel-plated aluminum, and nickel-coated graphite. The elastomer substrate is mainly silicon rubber or fluorosilicone rubber.

GoodBon's eSEAL™ EC series electrically conductive elastomer, extruded or sheetstock gasket, provide both excellent conductivity, and very good mechanical flexibility. Their applications include EMI shielding and environmental sealing requirement. Conductive particles include silver-plated aluminum, silver-plated glass, silver-plated nickel, silver-plated copper, nickel-plated aluminum, and nickel-coated graphite. And, the elastomer substrate can be chosen from silicon rubber or fluorosilicone rubbers to realize more stringent environment adaptability.

Selection suggestion

The classification of the above-mentioned commonly used materials is mainly based on performance requirements, application conditions and cost factors. For aerospace and aerospace products, the high shielding characteristics and high corrosion resistance of EC20 material can greatly improve the reliability and service life of the product. For industrial-level applications, EC24 &EC25 and The high conductivity of EC27 is suitable for occasions with high shielding requirements and good grounding.
The filler of EC21 is nickel-coated graphite, which has a cost advantage and is very light, which is suitable for the application of commercial grade and consumer electronics grade products. The materials mentioned in the list can be processed by extrusion molding, precision die-cutting, and composite molding with metal parts. The following pages show the special requirements of Rezdun's standard product size series for customers. We can fully meet customer structural requirements by customizing toolings.

Selection Guide

Remarks: Rectangular, D-shaped, M-shaped cross-section extruded rubber strip products can provide adhesive-backing options. After the gasket is backed with PSA(pressure sensitive adhesive), due to the different backing process and the existence of release paper, the length tolerance will be enlarged compared with the product without PSA backing. When the product is installed normally after tearing off the release paper, its dimensional tolerance can be restored to its original performance.
