Physical Properties of Materials*
* This chart shows the general physical qualities of
the materials used in Klein lineman’s body belts and
positioning straps. Due to the wide variety of condi-
tions in the workplace, this information should only
be considered as a general guide, and a qualified
person should evaluate the specific applications and
hazards to which the materials will be exposed. If you need more information, call Klein Tools at

Type of Material
Exposure to
Excessive Heat
Exposure to
Chemicals
Exposure to
Molten Metal or
Flame
Exposure to
Paints or Solvents
Nylon Poor resistance.
Becomes brittle,
has a shriveled
brown appear-
ance. Fibers will
break when flexed.
Weakens at 300°F
(149°C). Generally good
resistance except
around strong acids
and phenolic com-
pounds (phenol
is present in coal
tar and wood tar),
which cause it to
become brittle. Poor resistance.
Strands fuse
together and form
hard shiny spots.
Has hard and brittle
feel. Will not sup-
port combustion. Generally offers
good resistance.
However, paint
can penetrate into
the weave and dry.
This can cause
webbing to become
hard and brittle
and can eventually
break the fibers.
Some solvents
may affect fibers
(see “Exposure to
Chemicals”).
Klein-Kord ® Similar to nylon;
however, neoprene
will protect nylon
fabric for a period
of time. Excellent resistance
to hydrocarbons
as used in wood
treatment, due to
neoprene. Similar to nylon;
however neoprene
helps protect nylon
fabric from welding
splatter. Excellent resistance;
however, some
strong solvents
could soften
neoprene and
attack nylon.
Leather Poor resistance.
Excessive heat
destroys strength.
Will burn at 330°F
(165°C). Dry leath-
er slowly at room
temperature. Generally poor
resistance.
Chemicals tend to
dry leather out. Will burn; however,
chrome leather is
excellent protection
against welding
splatter. Generally poor
resistance.
Chemicals tend to
dry leather out.
