INDEXNew ceramifiable compound
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.
Ties that bind
3M is offering a new alternative for
electricians requiring rugged cable ties.
The 3M steel-barbed cable ties are said
to provide high strength and precision
tightening.
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.
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.
