Comparison of the Performance of Conductive PU Foam with Different Formulas

Conductive PU foam is a special material that combines conductivity and flexibility, widely used for electrostatic protection and shielding of electronic products. There are certain differences in the performance of conductive PU foam with different formulations. This article will compare several common formulations and specifically introduce the performance of Advanced Institute (Shenzhen) Technology Co., LtdYanbo brand conductive PU foam.

Common conductive PU foam formulas and their properties

1. Aluminum foil foam
   • Features: Aluminum foil cloth foam has good conductivity and shielding effect by compounding a layer of aluminum foil on the foam substrate.
   • Performance: High shielding effectiveness, low surface resistance, but relatively poor flexibility, suitable for situations that require high shielding effectiveness and low flexibility requirements.
2. Conductive fiber cloth foam
   • Features: Using conductive fiber cloth as the conductive layer, it has excellent conductivity and flexibility.
   • Performance: Stable conductivity, light weight, excellent compression fatigue resistance, suitable for application scenarios that require good conductivity and flexibility.
3. Gold-plated foam
   • Features: Plating a layer of gold on the foam substrate improves conductivity and corrosion resistance.
   • Performance: Excellent conductivity and good corrosion resistance, but high cost, suitable for occasions with extremely high requirements for conductivity and corrosion resistance.
4. Carbon coated cloth foam
   • Features: Using carbon coated cloth as the conductive layer, it has good conductivity and a certain degree of flexibility.
   • Performance: Stable conductivity, relatively low price, suitable for general conductivity and shielding needs.
