EMI Conductive Elastomer  

CMS Series  

Product Technical Datasheet  

General Introduction  

The electrically conductive elastomers are composed by adding conductive particles into elastomer system. They provide highly conductive,  

resilient gasketing functions for EMI sealing as well as pressure and environmental sealing. Conductive elastomers are used for shielding  

electronic enclosures against radiated electromagnetic interference (EMI). Usually, the shielding system consists of a conductive gasket  

sandwiched between a metal housing and cover. The primary function of these gaskets is to provide sufficient electrical conductivity across the  

housing/gasket/cover junction to meet grounding and EMI shielding requirements, as well as prevent intrusion of the moisture into the  

enclosure.  

In practical case, the electric enclosure consists of cover and housing, these two normally have flat, but rigid surfaces. When they are bonded  

together, slight surface irregularities on each surface prevent them from occluding completely at all points. These irregularities may be  

extremely minor, however they may work as leakage path for gas or liquid under pressure, and also for high frequency radiated electromagnetic  

energy. Such problem remains in flange sealing even when very high closure force is applied. However, when a conductive elastomer gasket is  

installed between the mating surfaces, and even minimal pressure is applied, the flexible elastomer gasket conforms to the irregularities in both  

mating surfaces. As a result, all surface irregularities and potential leak paths across the junction area are sealed completely against moisture  

and gas from environment, in addition, high frequency electromagnetic radiated energy penetration can be also attenuated.  

JONES has her own technology and developed different series of conductive elastomer products to meet various industrial applications.  

Advantages, such as excellent EMI shielding, excellent mechanical performance, great corrosion resistance, and easy mounting can be combined  

into product solution according to customer specification. New products will be continued to be developed to satisfy your need by deep learning  

your engineering design. JONES offer products available in the following types:

EMI Shielding Material V.A.2  

Version:  

Installation Guide  

As a general rule we recommend a gland fill, e.g. gasket width vs. groove width, of 85% ~ 95% for optimum shielding effectiveness. However, for  

critical applications that require both shielding and environmental sealing, a 95% gland fill is suggested. In addition, determining the height of  

the flange, the deflection of elastomer gasket is very important factor to be considered. Deflection is defined as the change in the cross

‐

sectional  

height of a gasket under compressive load and is a function of material hardness and profile. In general, to achieve sealing and EMI shielding, the  

minimum deflection of gasket should be greater than 10%. The optimum deflection should be chosen based on different configuration of  

elastomer gasket, its range varies from 5% for flat strip, 20

‐

25% for solid O type gasket, 15 ~ 20% for solid D type, 20 ~ 50% for hollow part.  

Material Specification  

Conductive elastomer has different electrical conductive property due to different conductive filler. JONES

‐

CMS Series 1 is filled with Silver  

Plated Glass(Ag/G), Military M Grade conductive elastomer has great performance

‐

price ratio, JONES

‐

ELM Series 2 is filled with Silver Plated  

Aluminum (Ag/Al), its Military B Grade products are suitable for outdoor application, it has lowest volume conductivity and best EMI shielding  

effectiveness, JONES

‐

CMS Series 6 is filled with Nickel Plated Graphite (Ni/C), although its volume resistance is 0.1Ohm/cm, it still has great EMI  

shielding performance, and excellent corrosion resistance, low cost solution, suitable for crucial environment.

Galvanic Corrosion Co

‐

extruded Conductive  

Elastomer  

Description  

Beijing JONES developed her own specialized technique to provide co

‐

extruded conductive elastomer inmass production.This series is major  

types of conductive elastomer with special performance against galvanic corrosion.  

Due to skin effect, only thin surface of conductive elastomer provide EMI shielding against radiated interference.When the fewer conductive  

parts are used, if the same volume resistance of conductive part of elastomer remains, as consequence, the same shielding effectiveness can be  

achieved. Beijing JONES developed special design for the cross section of elastomer, appropriated arrangement between conductive part and  

non

‐

condutive part has been adopted to completely eliminate the intrinsic galvanic corrosion of conductive elastomer. Through co

‐

extrusion of  

conductive part and non

‐

conductive part, strong chemical bonding between two parts is achieved, at the same time, co

‐

extrusion also provides  

advantages of reducing cost, better performanceprice ratio and better mechanical performance.  

Product  

Beijing JONES developed Easy

‐

Fit

‐

in type of conductive elastomer gasket to offer more working  

saving advantages.This product has hollow profile in cross section with very thin wall, this  

configuration gives the gasket more resilience and much lower werght.In  

practice, you only need to have flange with width equals or smaller than the width of the stripes, as  

consequence, it is not necessary to have adhesive tape on the back side to install the elastomer  

gasket, only press the gasket into the flange is enough to fix the gasket positon. The installation  

scheme is presented as follows:
