PA6.6 – Polyamide 6.6 PA66 GF50
AKROMID® A28 GF 50 9 EN MCL black (6429)
AKROMID® A28 GF 50 9 EN MCL black (6429) is a 50% glass fibre reinforced, process improved, foam injection moulding improved, electrical neutral, easy flowing polyamide 6.6 with very high rigidity and strength.
Components in mechanical engineering and housings for electronic parts in the automotive industry. AKROMID® A28 GF 50 9 EN MCL black (6429) is suitable for structural foam moulding.
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.
