PA6.6 – Polyamide 6.6 PA66-I GF20 + GB10
AKROMID® A3 GM 20/10 S1 nature (1217)
AKROMID® A3 GM 20/10 S1 natural (1217) is an 20% glass fibre reinforced, 10% glass bead filled, cold impact strength polyamide 6.6 with good surface, low warpage and light inherent color
Technical devices in automotive and engineering industry capable of carrying high load.
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.
