AKROMID®

B28 GM 10/20 1 LA black (4790)

PA6 GF10 + GB20

AKROMID® B28 GM 10/20 1 LA black (4790) is a 10% glass fiber and 20% glass beads reinforced easy flowing PA 6. It is characterised by a medium stiffness and strength. The material impresses with its laser markability along with very good surface properties and is therefore perfectly suitable for housings and covers in the automotive industry with high demands on the surface.
