CONDUCTIVE SILICONE

Product catalog summary
Overview: This document provides technical specifications for EMI shielding products manufactured by Ghiringhelli Mario, based in Italy. The products are designed for global distribution and are primarily composed of silicone-based materials with different fillers.
Specifications:
  • Materials: Two types of fillers are used: Silver-coated Copper (Sil-AgCu) and Nickel-Graphite (Sil-NiGr), both with a silicone base polymer.
  • Specific Gravity: Sil-AgCu has a specific gravity of 2.18 g/cmc, while Sil-NiGr is 1.97 g/cmc.
  • Thickness: Both materials range from 0.20 mm to 1.50 mm.
  • Hardness: Measured using ASTM D2240, Sil-AgCu has a Shore A hardness of 40 and Shore OO of 85, while Sil-NiGr has a Shore A hardness of 30 and Shore OO of 80.
  • Tensile Strength: According to ASTM D412, Sil-AgCu has a minimum tensile strength of 90 psi, and Sil-NiGr has 50 psi.
  • Elongation: Minimum elongation is 60% for Sil-AgCu and 50% for Sil-NiGr.
  • Compression Set: At 100°C and 25% compression, Sil-AgCu has a set of 6% thickness and 22% deflection, while Sil-NiGr has 7% thickness and 25% deflection. At 70°C, Sil-AgCu has a set of 3% thickness and 12% deflection, while Sil-NiGr has 5% thickness and 17% deflection.
  • Flame Resistance: Both materials meet UL94 HB and V-0 standards.
  • Volume Resistivity: Both materials have a volume resistivity of 0.2 Ohm-cm.
  • Shielding Effectiveness: Measured in dB at various frequencies (100MHz, 500MHz, 1GHz, 10GHz) using MIL G83528 standards, with effectiveness ranging from 85 dB to 120 dB depending on thickness and frequency.
Recommendations: The document advises that the provided data should be used as a general guide and not as a guarantee, as properties may change due to supplier improvements.
