PA6.6 – Polyamide 6.6 PA66 GF20 + GB10

AKROMID® A3 GM 20/10 4 WIT black (4530)

AKROMID® A3 GM 20/10 4 WIT black (4530) is a 20% glass fibre reinforced and 10% glass bead filled, hydrolysis/chemical stabilised polyamide 6.6 with good surface and low warpage.

Typical applications

Engineering parts, which are produced by water injection technology.

Processing information

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.
