Coating makes vent panels fire retardantCoating makes vent panels fire retardant

Friday, March 23, 2001

The StreamShield EMI vent panel has a thin layer of intumescent coating in the vent's honeycomb cells. When exposed to flames or heat at 300F, the coating expands rapidly, filling the cells with carbonaceous foam that prevents flames from propagating through the honeycomb.

The vents are typically used on telecommunication, data communication, and other electronic rack cabinets. The HEICF 1594 coating helps enclosures meet the requirements of network equipment building systems and Bellcore GR-63-CORE physical protection standards for fire resistance. The coating also meets ASTM E-84 Test procedures.

StreamShield EMI vents provide more than 50 dB shielding effectiveness from 1 to 10 GHz. Open area of the honeycomb is 85% with the intumescent coating.

The framed vents are available for round and rectangular opens. Additional features include integral conductive mounting gaskets, compression shops, and studs for push-in attachments.
