Electrically conductive foam
Handa Electrically conductive foam is a specialized material designed to combine the softness and compressibility of foam with the ability to conduct electricity. This unique combination makes it suitable for a range of applications where both physical cushioning and electrical properties are required.
Custom Manufacturing
Custom Electrically conductive foam
Handa Electrically conductive foam is made of polyurethane foam coated with copper and nickel.Compression is 25% to 75%. The maximum application temperature is between 60 and 70 degrees Celsius.
Custom manufacturing of electrically conductive foam involves a tailored process to meet specific application requirements. This process can be broken down into several key steps:
1.With or without self-adhesive
2.Supplied as sheets, strips or die-cuts
3.With water seal
4.Resistant to high temperatures, with cooling holes
5.Reinforced with woven fabric on 1 or 2 sides
6.PSA attachment method option
7.Nickel/copper metalization
8.X-Y-Z axis conductivity
9.Tolerance of ± 0.5 mm
10.I/O static applications/gasket replacement
Electrically conductive foam Manufacturing
Handa Electrically conductive foam is a specialty material made by incorporating conductive particles or additives into the foam matrix. The manufacturing process involves several key steps, which may vary depending on specific requirements and the manufacturer’s technology.
Here is a general overview of how conductive foam is typically produced:
- Foaming: The base foam, often polyurethane or polyethylene terephthalate (PET), is created through a foaming process that introduces gas bubbles, forming a cellular structure.
- Conductive Coating or Mixing: Conductive particles are either mixed into the liquid foam precursor before foaming or coated onto the foam’s surface after production. This can be done through impregnation, spraying, or dipping methods.
- Curing: The foam is cured to set its shape and ensure the conductivity of the added particles.
- Shaping: Cut or molded into specific shapes and sizes according to application requirements.
- Testing: Conductivity and compression set tests are performed to ensure the foam meets specifications.
