AKROLOY®

PA LGF 40 blue (7729)PA66+PA6I/6T LGF40

AKROLOY® PA LGF 40 blue (7729) is a 40% long glass fibre reinforced, semi-aromatic polyamide blend with extraordinary high stiffness and strength even at high temperature and very high impact and notched impact strength at elevated and low temperature even in conditioned state. PA LGF 40 blue (7729) distinguish due to isotropic mechanical properties, low shrinkage, higher heat deflection temperature and very good fatigue performance. The material has very good surface properties and is protected against the growth of microorganisms such as bacteria and fungi.
