AKROMID® B28 LGF 40 1 L black (6155) is a 40% long glass fibre reinforced easy flowing polyamide 6 with extraordinary high stiffness and strength even at high temperature and very high impact and notched impact strength at elevated and low temperature as well as a reduced density compared to standard PA6 LGF 40. B28 LGF 40 1 L black (6155) distinguish due to isotrop mechanical properties, low shrinkage, higher heat deflection temperature and very good fatigue performance. The material has very good surface properties.

Typical applications

Technical components in the automobile and mechanical engineering industries.

Processing information

The listed values are recommendations. Higher values should be used for higher glass loadings. We recommend only de-humidifying or vacuum dryers. Extensive drying can cause filling problems and surface defects.
