PA6 – Polyamide 6 PA6 GF33

AKROMID® B28 GF 33 1 GIT black (6846)

AKROMID® B28 GF 33 1 GIT black (6846) is a 33% glass fibre reinforced, heat stabilised polyamide 6. It is characterised by high stiffness and strength.

Furthermore, the material impresses with its good processability for gas injection technology and very good surface properties.

Therefore it is perfectly suitable for parts in the furniture industry, with high demands on the surface.

 

 

is therefore perfectly suitable for housings and covers in the automotive industry with high demands on the surface.
