PA6 – Polyamide 6 PA6 + X GF60

AKROMID® B3 GF 60 4 RM-M natural (4645)

21500 MPa

235 MPa

65 kJ/m²

AKROMID® B3 GF 60 4 RM-M natural (4645) is a 60% glass fiber reinforced, hydrolysis- and chemical stabilised polyamide 6 with low humidity absorption, very good surface finish and light inherent color.

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.
