Furthermore, owing its chemical
structure achieves good fire
resistance even without the use of
flame-retardant agents.
The advantages this material are
its very good electrical and
mechanical properties, its flexibility
and resistance breakage.
Compared with unreinforced PA,
this material can achieve UL94
flammability class HB.

W. The advantages
in comparison with are
better fire protection and the
higher continuous operating
temperature.
Glass fibre-reinforced
polyamide (PAGF)
offers excellent dimensional
stability and very good mechanical
properties.
This makes ideal for use end
brackets. Wemid fulfils the
strict requirements placed on
applications for railway rolling
stock 16-101.
However, the tracking resistance
is lower than other insulating
materials.
This thermoplastic
polyester (PBT)
offers excellent dimensional
stability (and therefore ideal
for plug-in connectors) and high
continuous operation temperature
