Spec 44
High temperature,
high performance
automotive wire
Spec 44 wire has a dual wall
construction which combines the
outstanding physical and electrical
characteristics of radiation crosslinked
polyalkene with the excellent
mechanical and chemical properties of
radiation cross-linked fluoropolymer.
The result is a wire insulation system
Ordering information
that offers a 170°C temperature rating,
small size, light weight, and resistance
to all known automotive solvents, fuels
and lubricants. Spec 44 Wire and cable
is highly flame retardant, non-melting,
does not cold flow and is easy to handle
in production using standard lead
preparation equipment.
Originally developed for aerospace and
military requirements in applications of
high density and complex circuitry,
Spec 44 Wire and cable now finds wide
use throughout the automotive industry
where environmental conditions
demand consistently reliable
performance.
