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
