PA6 – Polyamide 6 PA6 + PP GF40
AKROMID® B3 GF 40 8 L natural (7817)
AKROMID® B3 GF 40 8 L natural (7817) is a 40% glass fibre reinforced, heat stabilised polyamide-blend with a reduced density compared to standard PA6 GF 40.
Please note that this grade has no EU10/2011 and food approval anymore.
Technical components 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.
