AKROMID®
B28 LGF 40 1 L black (6155)PA6 + PP LGF40
AKROMID® B28 LGF 40 1 L black (6155) is an easy flowing PA6/PP-blend with reduced density compared to standard PA6 LGF 40. With 40% long glass fiber reinforcement the material is suitable for components with extraordinary high stiffness and strength even at high temperature and very high impact and notched impact strength at elevated and low temperature, where weight reduction is required at the same time. B28 LGF 40 1 L black (6155) distinguish due to isotropic mechanical properties, low shrinkage, higher heat deflection temperature and very good fatigue performance. The material has very good surface properties.

Processing information
The values mentioned are recommendations. We only recommend desiccant / dry air dryers or vacuum dryers. Too long a drying time and the resulting residual moisture content below the lower limit can lead to filling problems and surface defects. The specified drying time refers to closed and undamaged bagged material. When processing from previously opened bags or from octabins with polyolefin inliners, a longer drying time may be necessary. It is recommended to check the residual moisture content after the drying process.
