AKROMID®
C28 GF 25 FRT grey (8331)PA-Blend
AKROMID® C28 GF 25 FRT grey (8331) is a 25 % glass fiber reinforced, flame retardant and easy flowing PA blend, colored in grey similar to NCS S 3000 N. The material is based on a flame retardant system that is free of red phosphorus and halogens. This grade is suitable for railroad applications and certified to EN 45545-2 R6 and EN 45545-2 R1. To achieve an excellent surface quality a mould temperature of at least 120°C is necessary.

Processing information
The values mentioned are recommendations. We only recommend desiccant / dry air dryers or vacuum dryers. Too long a drying time and the resulting residual moisture content below the lower limit can lead to filling problems and surface defects. The specified drying time refers to closed and undamaged bagged material. When processing from previously opened bags or from octabins with polyolefin inliners, a longer drying time may be necessary. It is recommended to check the residual moisture content after the drying process.
