Material Specifications
Polyamide (PA 66)
WAGO uses modified, halogen-free,
flame-retardant polyamides. Fire protection
equipment enables classification flamma-
bility class per even for extremely
thin walls.

In lower temperature ranges, has been
determined that damage the insulation
material occurs during usage down −35°C
(−31°F).
Polyamides have excellent resilience against
the most demanding climates and have
proven themselves tropical applications
worldwide.
Polyamide (PA 46)
In comparison with 66, has sub-
stantially higher dimensional stability under
heat. After installation and wiring, WAGO
products can even used temperatures
down −60°C (−76°F).31

Polyamides are resistant most fuels,
greases, and oils, well the most com-
monly used cleaners, such alcohol, Freon,
Frigen, and carbon tetrachloride.
Adhering 746C, the polyamides used at
WAGO have continuous operating tem-
perature 105°C (221°F) based the rela-
tive temperature index with impact load
(RTIimp).
Depending the demands placed the
finished product, WAGO uses polycarbon-
ates that carry flammability classifications V2
and per 94.
The permissible short-term temperature for
the type used WAGO 280°C (536°F). This ensures that the necessary
electrical and mechanical insulating proper-
ties are maintained sufficiently guaran-
teed level over long period time.
These materials not corrode, are difficult
to ignite and feature self-extinguishing prop-
erties (V0 rating per 94).
The short-term upper temperature limit is
200°C (392°F). Highly precise components can be
created due the low shrinkage the mate-
rial during injection molding.
In practical use, basic stabilization WAGO’s
polyamides has been proven over many
years sufficient prevent damage
caused ozone radiation exposure in
intended applications. Its excellent elec-
trical insulating properties and dimensional
stability are virtually independent environ-
mental conditions, such humidity and tem-
perature.

The use insulation materials during
in-house production WAGO only occurs
after acceptance factory test certificates
and specified material tests. PPA absorbs minute amounts
of moisture from the atmosphere making it
ideal for reflow soldering applications and for
thin-walled, dimensionally stable compo-
nents.

polyamides with optimum elasticity, strength
and durability.
In general, materials are used that have
excellent tracking resistance, flammability
ratings and high temperature resistance.

Polycarbonate (PC)
Polycarbonate has excellent dimensional sta-
bility under heat.
Polyphthalamide (PPA GF)
Glass-fiber-reinforced, high-performance
polyamides are ideal for high-temperature
applications, due the material’s high level
of thermal dimensional stability, its low
dependence ambient conditions and its
excellent strength properties.
The presence anaerobic earth bacteria,
mold, fungus and enzymes does not degrade
the material. Insulation parts made polyam-
ide are resistant insects. The material does
not provide oxygen other biogenic ele-
ments microorganisms.
Glass Fiber-Reinforced Polyamide
(PA GF)
WAGO uses glass-fiber-reinforced polyam-
ides for components with increased mechan-
ical demands, such levers, push-buttons
or housings exposed high stress, because
they have significantly better mechanical
characteristic properties than non-reinforced
polyamides.6. The electrical and mechani-
cal properties remain intact extremely high
