Medical And Industrial Equipment EMI Shielding Conductive Rubber Material

Product Detail

Medical and industrial equipment EMI shielding conductive rubber material


Product Description:

E-coating conductive rubber is a kind of high-performance composite product which is coated with conductive metal particles on the surface of non conductive elastomer. The good elasticity of the inner non conductive elastomer ensures the good toughness of the product, and facilitates the assembly of the product while achieving environmental sealing and preventing water or other dust from entering the interior of the equipment.

E-coating conductive rubber combines the high shielding characteristics of the conductive layer with the mechanical properties of the non-conductive elastomer. It is a patented product with independent intellectual property rights of DEM




Features And Advantages:

?An elastic inner core without metal fillers, with optimized compression and aging characteristics

?The conductive layer material is uniformly coated in the outer layer film and has excellent conductive characteristics

?With the special coating process, the cost of noble metal is effectively saved without reducing the conductivity and shielding performance

?Compared with the full solid filled elastomer, the attenuation performance does not decrease under full compressive force

?Very low compressive force and resistance to deformation

?A variety of conductive material optional                  

 

Application:

?Mobile communication

?National defense

?Automobile

?Space flight

?Medical care
