properties. Brief peak temperatures of
up to 200°C are permissible as a result
of heat aging stabilization. Polyamide
absorbs moisture from its surroundings,
on average 2.8%. However, this moisture
is not crystallization water in the plastic
itself, but chemically bonded H2O groups
in the molecular structure. This makes the
plastic flexible and resistant to breakage,
even at temperatures as low as -60°C. PA
belongs to inflammability class V2 to V0
as per UL 94. Polyamide, used by Phoenix
Contact, is silicone- and halogen-free and
is suitable for use in temperatures between
-60°C and +125°C.

chlorine and bromine in flame protection
agents. This also forbids the use of flame
protection agents containing halogen in
accordance with DIN EN ISO 1043-4. This
means that, according to the definition in
the ZVEI position paper (requirements for
the use of halogen-free products in the
electrical and electronics industry), no flame
protection agents containing halogen or PVC
are present in the components.
Polyester is a chemical-resistant material.
It is ideally suited to printing, shaping
and punching. Polyester is resistant to
UV radiation and absorbs little moisture.
Polyester, used by Phoenix Contact, is
silicone- and halogen-free. Depending on
its composition, it is suitable for use in
temperatures between -40°C and +150°C.
Polycarbonate (PC)
Polycarbonate has a high mechanical
strength and chemical resistance.
Rigidity, dimensional stability and good
heat distortion resistance are further
distinguishing features of this material.
Polycarbonate is used to manufacture
particularly smooth and stable marking
materials. Polycarbonate, used by Phoenix
Polyolefins
Polyolefins are semi-crystalline
thermoplastics, which can be easily
processed as extrusion profiles (shrink
sleeves).
