Stretch Conductive Fabric

Stretch Condutive fabric

 Stretch Conductive Fabric 4900

Stretch conductive fabric coated with medical-grade silver coating for EMI. Highly conductive, conductivity increases by up to 25% as stretches.

This conductive fabric is coated with a medical-grade silver coating and has a broad range of applications, since it can be stretched in both directions – lengthwise even up to 100% of its original dimension! The fabric can be used as an antibacterial wound or burn dressing (note: the material is not supplied sterile) but it is also a great material for electrode contacts, clothing, or other shielded garments. Not only is the material highly conductive, but the conductivity increases up to 25% as it stretches, which is convenient for smart textile applications. The silver coating is 99,9% pure.

Advantages
  • The width of the fabric affects the percentage of conductivity
  • The material is very consistent in quality
  • When the material is stretched lengthwise, its conductivity increases; when you stretch it crosswise, conductivity decreases
  • Crosswise the fabric can be stretched by around 60%, and lengthwise by almost 100%
Applications
  • “Intelligent” or shielding garments
  • Cable shielding wrap
  • Hobbies or technology where a change in conductivity with stretch is important

Stretch conductive fabric is very supple, can be stretched in all directions and is silver coloured

Stretch conductive fabric stretches easily and remains electrically conductive

Stretch conductive fabric can be supplied on a roll with a maximum width of 1350 mm
