27NL202_TDS.pdf

Flexibility and excellent conformability make NL20 possible to
be easily integrated into fast production cycles.
This product can be processed by hand layup, vacuum bagging
and infusion processes and will withstand manufacturing
temperatures up to 150 C.
The unique properties of NL20 such as: a closed air filled cell
structure, low water absorption, rot resistance and high level of
noise and vibration attenuation make it an excellent material
for to the composites industry – perfectly aligned with the new
green classi cations.
