Plenum and fire retardant
compounds
New formulation technology for Teknor Apex FireGUARD® low-flame,
low-smoke plenum compounds eliminates much of the high cost of
connectorisation in plant or campus data networks by making continuous
indoor/outdoor (I/O) optical fibre cables possible. The I/O formulations
provide the UV resistance and anti-microbial properties required for outdoor
exposure without trade-offs in the physical, electrical and flame and smoke
properties available with standard FireGUARD grades. The new formulations
are available for all FireGUARD compounds used as jackets in plenum
applications.
In large corporate or institutional settings, FireGUARD I/O compounds
for optical fibre cables withstand exposure to solar UV and fungus, while
passing the rigorous tests for flame and smoke performance required to
ensure indoor safety. Continuous cabling enables installers to avoid the
added time, hardware, and cost for connecting outdoor cable to indoor at
the point where it enters a building. A new class of thermoplastic elastomer
(TPE) compounds, fully RoHS-compliant, meets stringent UL criteria for fire
retardance while providing flexibility and toughness over a broad temperature
range. The new additions to the Elexar® product range are available with
hardnesses from Shore 56A to 90A and recommended for insulation, jackets,
and moulded parts for flexible cords, coil cords and cables in power tools,
appliances, industrial robots, welding equipment, and entertainment audio
and lighting systems. All grades meet UL94 V-0 flame test requirements and
are formulated to pass UL-1581 continuous rating of 125°C.
