Wemid modified thermoplastic
with properties that have been
specially devised suit the
requirements Weidmüller
connectors.
Polyamide (PA) one the
most common commercial plastics. Wemid fulfils the
strict requirements placed on
applications for railway rolling
stock 16-101.71282250000 2012/2013
.
This thermoplastic
polyester (PBT)
offers excellent dimensional
stability (and therefore ideal
for plug-in connectors) and high
continuous operation temperature. The advantages
in comparison with are
better fire protection and the
higher continuous operating
temperature.
The advantages this material are
its very good electrical and
mechanical properties, its flexibility
and resistance breakage.
Glass fibre-reinforced
polyamide (PAGF)
offers excellent dimensional
stability and very good mechanical
properties.

This makes ideal for use end
brackets.
Compared with unreinforced PA,
this material can achieve UL94
flammability class HB.
Furthermore, owing its chemical
structure achieves good fire
resistance even without the use of
flame-retardant agents.
However, the tracking resistance
is lower than other insulating
materials
