CONDUCTIVE FOAM

Product catalog summary

Introduction
Ghiringhelli Mario, based in Italy, specializes in EMI shielding products. Their conductive urethanes are composed of three layers: PET, PU, and PET, which are heat-sealed and made conductive through a chemical-galvanic bath with copper and nickel. These materials are suitable for creating punching gaskets for flanges and connectors and are particularly effective for shielding cells.

Compliance
The products are UL and RoHS compliant, ensuring they meet safety and environmental standards.

Physical Properties

Tensile Strength: 16/6 Kg/inch (warp/weft)
Tearing Strength: 2.3/1.9 Kg
Elongation: 28/20%

After wet-heating tests at 60°C and 90% humidity for 100 and 300 hours, the tensile strength slightly decreases, and surface resistivity increases marginally.

Environmental Resistivity
Surface resistivity is measured at different stages, showing slight increases after wet-heating and salt-spraying tests.

EMI Shielding Performance
The product demonstrates significant attenuation in both magnetic and electric fields across a frequency range of 0.1 to 1000 MHz, as per MIL-STD-285 standards.

Thickness: 3.4 mm
Weight: 316 g/m²
Max Short Duration Temp.: 70°C
Surface Resistivity: < 0.03 Ω/sq
