AEI Introduced new Ceramifiable technology for Fire Survival Cables at Wire 2014.

Following a successful week at Wire 2014 show in Dusseldorf, AEI Compounds Ltd. UK, a market-leading manufacturer of cable compounds, introduced a new, innovative thermoplastic Halogen Free Flame Retardant (HFFR) compound, TP-0851.There were over 250 visitors representing 150 companies to the stand from 35 international countries.

TP-0851 is a new ceramifiable HFFR sheathing compound for cables built to preserve circuit integrity in fire situations.  TP-0851 has been used successfully in emergency alarm, communication and lighting circuits. Other fire-survival cable applications are now being tested using the ceramifiable HFFR compound technology developed by AEI.

The ceramifiable sheathing material forms a strong char during burning, providing enhanced cable fire protection and enables the cable to function in serious fire situations. When TP-0851 is used with silicone rubber insulated cores the most onerous fire performance specifications can be satisfied.  Traditional fire survival cable constructions using Mica tapes may be eliminated.  The use of TP 0851 for cable sheathing in certain cable constructions allows improved cable production efficiency and faster cable termination performance.

TP-0851 sheathed cables have met the fire test requirements of BSEN 50200 for PH 120 and the enhanced BS 8434-2 with a 930°C flame and water spray with aluminium laminate tape screens.

The ceramifiable technology developed for TP-0851 may have wider applications in different cable constructions.  Please contact us for technical and commercial discussions.

Silane crosslinked oil resistant HFFR compounds SX-0620, for railway, shipboard, oil & gas installations, crosslinked HFFR materials are now being specified for cable sheaths for an increasing number of projects.Compounds based on peroxide cure & e beam cure have been available for sometime. A silane cured compound solution is now available which gives good oil resistance & good cable flexibility. SX-0620 meets IEC60092-359 SHF2 and EN50264 EM104 and has very good abrasion resistance. We are also working towards a NEK606 version.
