PA6.6 – Polyamide 6.6 PA66-I

AKROMID® A3 2 S1 grey (5972)

AKROMID® A3 2 S1 grey (5972) is an unreinforced, impact modified PA 6.6. The material is UV-stabilised and characterised by a very high cold impact strength. Therefore, it is perfectly suitable for connecting and fixing systems which are used in the automotive, electro and furniture industry where a very high impact strength even at low temperatures is required. The color is similar to RAL 7042.
