Preliminary datasheet

PA6 – Polyamide 6 PA6 + PP GF30

AKROMID® B3 GF 30 4 L black (7481)

9000 MPa

145 MPa

70 kJ/m²

AKROMID® B3 GF 30 4 L black (7481) is a 30% glass fibre reinforced and hydolysis stabilised polyamide-blend with a reduced density compared to standard PA6 GF 30

Typical applications

Mainly 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.
