PA6 – Polyamide 6 PA6 + X GF50

AKROMID® B3 GF 50 4 RM-M black (3221)

75 kJ/m²

AKROMID® B3 GF 50 4 RM-M black (3221) is a 50% glass fibre reinforced, chemical stabilised polyamide 6 with low humidity absorption and very good surface finish.

Typical applications

Housings and other dimensional stable parts in the automotive and electronic industry demanding high resistance against CaCl2-solvents, as well as a very good surface.

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.
