Flammability of igumid NB
All easy e-chains ® and series 14, F17 e-chains ®
are made from the fl ame-retardant igumid ® NB
material. These e-chains ® have the following
fl ame-retardant classifi cations:
● UL94 classifi cation - V2
● VDE 0304 part 3/5.70 classifi cation - IIb
● DIN 4102 fl ammability of materials - B2

temperatures are possible with igumid ® G,
short-term up to +180°C (370°F). However, the
mechanical values are reduced and the service
