Nylon 6/6 — General Purpose
General purpose nylon 6/6 features light
weight, high strength and a wide temperature
range. It is halogen free so it does not release
dangerous gases, such as chlorine, bromine,
fluorine and iodine when burned. Nylon 6/6 is
hygroscopic, and therefore, absorbs or
releases moisture depending on its environ-
ment. Thus, the moisture level of the materi-
al will affect tensile strength, stiffness and
elongation of the product.
Nylon 6/6 — Heat Stabilized
With similar properties and benefits as nylon
6/6, products manufactured with heat stabi-
lized nylon 6/6 material have a chemical
stabilizer added for higher continuous
temperature applications.
Nylon 6/6 — UV Stabilized
Chemical inhibitors are used to give nylon
6/6 material added properties to fight against
premature aging of products due to the
effects of ultraviolet rays.
Nylon 6/6 — UV Stabilized
(2% Carbon for Military Specification)
The physical properties of this material
include carbon, which acts as a UV stabiliz-
er, prolonging the life of the product under
ultraviolet conditions. It also allows cable ties
to meet the particular military specification
for cable ties.
Nylon 6/6 — V0 Flame Retardant
This material meets UL 94V-0 flammability
requirements. Flame retardant additives
generally reduce tensile strength when com-
pared to general-purpose nylon 6/6, but this
resin has been formulated to minimize such
effects.
Nylon 6/6 — High Impact
Impact modifiers are added to increase flexi-
bility. High impact nylon 6/6 has stable ten-
sile strength due to its reduced influence
from moisture. It is excellent for high vibra-
tion applications, as within the aircraft and
automobile industries and performs better
than nylon 6/6 against ultraviolet rays. Good
for outdoor use.
Polypropylene
Polypropylene is used in environments where
chemical effects on nylon are a concern. It is
not affected by inorganic acids (hydrochlo-
ric), polyhydric alcohols (ethyleneglycol),
neutral salts (sodium chloride) and basic
salts (sodium bicarbonate). Polypropylene
also resists a number of other chemicals with
good results, although it has lower tensile
strength than nylon 6/6 (about half).
Polypropylene has good UV resistance.
Tefzel
®
Although about two-thirds the strength of
nylon 6/6, Tefzel is resistant to a wide range
of chemicals, such as concentrated hydroflu-
oric and sulfuric acids. It is also a low water
absorbing material, therefore, is not adverse-
ly affected by water. Tefzel is radiation resist-
ant up to 100 megarads and meets the fire
and smoke requirements of IEEE 383. Tefzel
also withstands high temperatures and ultra-
violet light exposure. Products made from
Tefzel material also have non-outgassing
properties for zero gravity applications.
Halar
®
Halar is similar to Tefzel in performance and
benefits. Halar is recognized for its low
smoke density attribute when burned. This
makes products made out of Halar more
desirable for use in areas where smoke gen-
eration is a concern, as when bundling wire
and cable in air handling spaces.
