Technical Datasheet | Supplied by Byk (Altana Group)
BYKO2BLOCK-1200 by Byk (Altana Group) is a modified aluminum-magnesium clay. Acts as a permeability reducer to gas and water vapor. It is based on a platelet-forming, modified phyllosilicate. During processing, the separated platelets are distributed equally in the polymer matrix, which results in reduced permeability. It also improves thermal endurance. The platelet-shaped particles formed during the compounding create a so-called winding pathway for the gases, thereby reducing this the permeability. BYKO2BLOCK-1200 can achieve a significant improvement in impermeability towards gases such as oxygen, carbon dioxide and water vapor, without changing other properties such as the mechanics or transparency. It is compatible with polylactide (or polylactic acid). It can be used in foodstuff packaging films and in the packaging industry. Its recommended dosage rate is 3-5%.
