A functional material, conductive fabric covered polyurethane foam, is commonly known as FOF (Fabric Over Foam). The product inherits good electrical conductivity and abrasion resistance from conductive fabric and good resilience from polyurethane. It is a widely adopted economical conductive gasket filler. The products are commonly seen in consumer electronics for EMI shielding, electrostatic discharge and grounding.
These products are die-cut customized parts, usually used in I/O interface of computers and telecommunications enclosures to achieve EMC, grounding and other functions. Such products require customer drawings, and verifications from both customer and manufacturer are necessary before proceeding to prototyping and production.
