PA6.6 – Polyamide 6.6 PA66
AKROMID® A4 5 EN black (5111)
AKROMID® A4 5 EN black (5111) is an unreinforced, high temperature stabilised, electrical neutral, high viscosity polyamide 6.6
Highly stressed parts such as gear-wheels, bearing cages, cable connectors and coil formers.
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.
