Conductive foam gaskets consists of outside conductive fabric and foam ,used for high-level EMI shielding which has large tolerance.

Based on their elasticity and consistency,they are widely used in occasions that need low closure force and Minimum compression deformation, especially for commercial-grade electronic chassis, could meet 80dB shielding effectiveness during some frequency range.

 

Performance

Shielding effectiveness 60 dB~80dB/30MHz~1GHz(ASTM4935)
Surface resistance <0.07ohms/sq inch
Permanent deformation ﹤10%
Temperature range  -10℃~110℃
Flammability UL94(HF-1)
Corrosion resistance Compatible with aluminum, galvanized iron, iron plating and other materials electrochemical plating
Tear strength Binding force test standards: AATCC TM8; Unit: level; Value: ≥ 4
Compression 30-50%.  Design the data of conductive foam shape and size for reference, could have good electrical conductivity and shielding during the range.
Permanent deformation When ambient temperature is 70°C and compression is 50%, hydrostatic compression material 24 hours,hydrostatic compress material 24 hours , then remove the pressure,placed in a natural state for 24 hours under normal temperature, compression range may not exceed 10% of its original height.
Pressure compress 30% hardness is 55 +/- 5 degrees; compress 50% hardness is 75 +/- 5 degrees.

 

Application:

●widely used in the occasion of capacity and closing pressure, and cost lower. especially for high-performance shielded occasion which has good fit.

●Widely used in electronic box, case, interior chassis, industrial equipment, notebook PC, mobile communication devices etc.

 

Mounting

● Use adhesive tape to mount. Mounting tolerance ±1mm, the length tolerance ±2mm.

● Keep the mounting surface clean, no oil or dust. Put enough pressure after paste.

● Do not tear off after mounting. If must tear off,can not use again.

●Do not touch with hands, must wear clean gloves when mounting.
