Vermiculite is a hydrous phyllosilicate mineral used as an absorbent.  At Hazpak we use vermiculite as a filling agent when packaging of chemicals and other liquid goods for freight in code 1, 2 or 3 UN Approved Boxes.  Vermiculite is most commonly used in Acoustic panels, Roof and floor screeds and insulating concretes.  Vermiculite is also used by nurseries for seed germination and as a soil conditioner.
