PA6.6 – Polyamide 6.6 PA66 GB30

AKROMID® A3 GK 30 natural (3689)

AKROMID® A3 GK 30 natural (3689) is a 30% glass bead filled polyamide 6.6 with low warpage and high surface appearance and light inherent color

Typical applications

Highly integrated housings in the appliance industry

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.
