Limestone is a sustainable raw material, with abundant reserves all over the world. It is 100% self-sufficient and said to be almost inexhaustible. We believe that this sustainable material can save the world.
LIMEX is suitable for diverse moulding methods including injection moulding, extrusion moulding, vacuum moulding, and blow moulding. Though LIMEX is a composite material, it does not require custom equipment and can be processed using traditional methods and machinery. LIMEX is used by more than 6,000 companies and municipalities for a variety of purposes. (As of June 2021)
LIMEX is an advanced material produced from calcium carbonate (CaCO3), which is derived from limestone, and a small amount of polymeric resin added as a binder. These materials are heated and kneaded in a twin screw extruder, creating a molten, homogeneous composite containing over 50% calcium carbonate by body weight. Next, the composite is heated and pressurized treated under LIMEX’s proprietary manufacturing process, resulting in material properties ideal for post-processing.
LIMEX pellet is manufactured by pelletizing, the process of molding the molten composite into the shape of a pellet. LIMEX pellet is also manufactured by pelletizing edge waste produced through manufacturing and printing process or used LIMEX sheets collected from consumers. Since the amount of petroleum-based resin contained in conventional plastic products can be reduced, LIMEX is used as a material to “reduce plastic”.
LIMEX sheet is manufactured by T-die sheet extrusion of the molten composite, and stretching process controlling a porous structure in order to create whiteness and lightness. Next, specific coating agent is applied onto the surface of LIMEX sheet depending on its application, enhancing surface properties for various kinds of printing process. Stone paper and LIMEX Sheet are different products.
