PA6.6 – Polyamide 6.6 PA66 GF50
AKROMID® A3 GF 50 6 black (6860)
AKROMID® A3 GF 50 6 black (6860) is a 50% glass fibre reinforced, inorganic high heat stabilised polyamide 6.6 with very high stiffness and strength.
Functional parts in mechanical engineering and 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.
