PA6 GF 25 FR (40)
AKROMID® B3 K1 FR natural (8045)AKROMID® B3 K1 FR natural (8045) is a 25 % glass fibre reinforced and flame retardant PA 6. The flame retardant system is free of halogens and red phosphorus. Due to its high stiffness and strength, the material is suitable for panels, arm rests, protective caps and other small parts. It meets the requirements of EN 45545-2 R21 HL3, R22/23/24 HL2 for public transportaition. The very good flowability achieved an improved surface quality and it is optimized for self coloration.

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.
