PK-VM FR natural (8658)PK FR(40)

AKROTEK® PK-VM FR natural (8658) an unreinforced, flame retardant and process improved Polyketone compound. The flame retardant system is free of red phosphorous, PFAS, melamine, halogens and antimony trioxide. The product is characterised by its high dimensional stability and consistent mechanical properties, even under different conditions. It also demonstrates excellent chemical and hydrolysis resistance.
