AKROMID® B3 GF 25 FRT black (7148) is a 25% glass fibre reinforced, halogenfree flame retardant polyamide 6 with high stiffness and strength.

Typical applications

Special applications in the railway sector, e.g. Armrests, removable headrests or

small-volume non-listed components

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.
