Using ordinary silicone elastomer as the substrate, mixed with conductive particles with good conductive properties, ECE is a compound made through a series of complex mixing, vulcanizing and other process. It is the perfect combination of flexibility of the silicone elastomer and high conductivity of conductive particles. Products are not only suitable for conductive grounding and EMI shielding, but also ideal to achieve environmental sealing. Typical conductive particles include silver-coated aluminum, silver-coated glass, silver-coated nickel, silver coated copper, nickel-coated aluminum and nickel-coated graphite, etc. The elastomer base material is mainly silicon or fluorosilicone.
Product Features
The classification of the commonly used conductive elastomer materials is mainly based on performance, application conditions and cost. For military-grade applications, high shielding properties and high corrosion resistance of AERO-SEALOR ECE509 can greatly improve product reliability and service life. For industrial-grade applications, high electrical conductivity of AERO-SEALOR ECE501, AERO-SEALOR ECE505 and AERO-SEALOR ECE 507 is suitable for high shielding and grounding requirements. The fill of AERO-SEALOR ECE503 is nickel-coated graphite; which is cost effective and very light. Product is suitable for commercial and consumer electronics applications. For following listed materials, they can be processed by AEROBON through extrusion, molding, precision die cutting, and complex molding together with metal parts. The following pages give the standard AEROBON product range. We can also customize the tooling to meet the customer's special structural requirements. |
Selection Guide Notes: Rectangular, D-section, M-section extruded strip products have PSA options. Due to the different processes of adhesive and the existence of release liner, compared with non-adhesive products, the length tolerance would be enlarged. When the product is peeled off the release liner and installed, the dimensional tolerances can be restored to the original state.
