AKROMID® B28 GF 50 9 natural (6570) is a 50% glass fibre reinforced, easy flowing polyamide 6 with very high stiffness and strength

Typical applications

Mainly components in mechanical engineering and the automotive industry demanding 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.
