PA6 – Polyamide 6 PA6 GF 25 FR
AKROMID® B3 GF 25 FRT black (7148)
AKROMID® B3 GF 25 FRT black (7148) is a 25% glass fibre reinforced, halogenfree flame retardant polyamide 6 with high stiffness and strength.
Special applications in the railway sector, e.g. Armrests, removable headrests or
small-volume non-listed components
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.
