PA6.6/6 – Polyamide 6.6/6 PA66 + PA6 GF 50
AKROMID® C3 GF 50 5 XTC natural (4946)
AKROMID® C3 GF 50 5 XTC natural (4946) is a 50% glass fibre reinforced, high temperature stabilised polaymide 6.6/6 - Blend with very high stiffness and strength and extra high temperature tolerance.
Components in mechanical engineering and in the automotive industry.
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.
