PA6 + PP LGF50
AKROMID® B28 LGF 50 1 L black (5928)
AKROMID® B28 LGF 50 1 L black (5928) is a 50% 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 50. B28 LGF 50 1 L black (5928) distinguish due to isotrop mechanical properties, low shrinkage, higher heat deflection temperature and very good fatigue performance.
Technical components in the automotive and electronic industry, where a weight and cost reduction is required.
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.
