Inquiry The Products Or Relations


Electrically Conductive Elastomer Caps is a generic term referring to any rubberized material with conductive properties, such as glass silvering, silver-plat aluminum, silver, etc. These kind of conductive particle are well – dispersed in the silicone rubber. Conductive network forms when the neighboring conductive particles contact under pressure. It reduces or eliminates the EMI/RFI (electromagnetic interference and radio frequency interference) noise that is often associated with electronics.

Electrically Conductive Elastomer Feature:Electrically Conductive Elastomer main function is to seal and electromagnetic shield.

Electrically Conductive Elastomer Main Principles:

1.Conductive particles filled inside the electrically conductive elastomer reach a certain volume number, and contact one another, finally form electron continuous state. When strong electromagnetic wave in external electromagnetic field hits free electrons in conductive particles, forming an opposite electromagnetic field, internal and external electromagnetic field offset each other to weaken the effect of electromagnetic interference wave.

2.Electrically conductive elastomer another principle is energy transformation, in other word, law of conservation of energy. When electromagnetic wave hits free electrons, conductive particles generate heat in the process of electrons movement, which is electromagnetic interference wave – free electron movement kinetic energy-thermal energy, in order to weaken the electromagnetic interference.

Electrically Conductive Elastomer Material Choice

When working with electrically conductive elastomer , it’s important to remember that galvanic compatibility will also have an effect on which wire type or filler should be used. in this case, a conductive wire type or filler choice needs to be made where the difference in voltage potential between the dissimilar metals are as small as possible.
