  • Surface Resistivity: 10⁸ to 10¹² ohms/sq
  • Static Decay: Less than 5 seconds (5000 to 50 volts)
  • Flammability: Combustible solid with fire risk at high temperatures or sparks
  • Leach Test: Minimal leachable anions (chloride at 88 ppb, nitrate at 3.9 ppb) for contamination-sensitive environments
• Applications: Ideal for ESD-sensitive packaging, suitable for delicate electronics requiring contamination control.

AFDF (Polyethylene Foam – Antistatic)

• Material Overview: Closed-cell polyethylene foam known for its lightweight, non-abrasive properties, providing surface protection and light-duty cushioning.
• Key Properties:
  • Compressive Strength: Varies with thickness, e.g., 1/32″ has 2.3 psi at 25% compression.
  • Water Absorption: Less than 0.1 lbs./ft², offering superior water resistance.
  • Thermal Resistance: Exhibits R-value depending on thickness, making it an effective thermal insulator.
  • Static Decay: Less than 2 seconds, available in antistatic grades.
• Applications: Suitable for light-duty cushioning and surface protection for fragile electronics, automotive parts, and consumer goods.
