Preliminary datasheet

PA6 – Polyamide 6 PA6+PP GF50

AKROMID® B3 GF 50 4 L black (7833)

14500 MPa

175 MPa

65 kJ/m²

AKROMID® B3 GF 50 4 L black (7833) is a 50% glass fibre reinforced, hydrolysis stabilised polyamide-blend with a reduced density compared to standard PA6 GF 50

Typical applications

Technical components in the automotive and electronic industry, where a weight and cost reduction is required

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.
