New ceramifiable compound

Designed to fasten wire bundles and harness components quickly and securely, the cable ties consist of a smooth nylon strap with a head, or pawl, containing a stainless steel barb. When engaged, the barb presses into the nylon strap, providing a tight grip and a strong, long-lasting hold.

AEI Compounds Ltd has developed a new thermoplastic halogen free flame retardant compound, TP0851; a ceramifiable sheathing compound for cables designed to preserve circuit integrity in the event of fire. TP0851 has been successfully tested in emergency alarm, communication and lighting circuits. Other fire-survival cable applications are now being tested. The ceramifiable material forms a strong char during burning, providing enhanced cable fire protection, and allows the cable to continue to function in serious fire situations. When TP0851 is used with silicone rubber insulated cores it will comply with even the most strenuous fire performance specifications. Traditional fire survival cable constructions using Mica tapes are unnecessary. The use of TP0851 for cable sheathing in certain cable constructions is said to improve cable production efficiency and allowfaster cable terminationperformance. TP0851-sheathed cables have met the fire test requirements of BS EN 50200 for PH120, and the enhanced BS 8434-2 with a 930°C flame and water spray with aluminum laminate tape screens.

Designed without notches, the 3M barbed cable tie has infinite locking positions, at any point along the strap, allowing more precisepositioning than typical ratchet-type cable ties. The nylon strap’s ribbed pattern provides extra grip to prevent slippage. The cable ties are available in black and natural, and in seven different lengths between 4 and 28 inches.
