Limex

LIMEX™ Sheet

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, a 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.

LIMEX™ Pellet

LIMEX™ pellet is manufactured by pelletizing, the process of moulding 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™: Pioneering Sustainable Alternatives

LIMEX™ is an advanced sustainable 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.

Flexible Moulding Using LIMEX™

LIMEX™ is versatile, accommodating a variety of moulding techniques such as injection, extrusion, vacuum, and blow moulding. As a composite material, LIMEX™ seamlessly integrates with standard equipment, allowing for processing through conventional methods and machinery.

The Power of Limestone

LIMEX™, our groundbreaking material, draws its strength from an unexpected source: limestone. Here’s why it matters:

Global Abundance: Limestone is abundant worldwide. Unlike oil, water, or forests, it poses minimal depletion risk. This availability ensures a stable supply chain for LIMEX™ production.

Sustainability in Supply Chains: As the UK and Europe pivot toward sustainable practices, LIMEX™ emerges as a beacon. It’s more than a substitute—it’s a solution. Imagine plastic packaging with less than 50% plastic content yet maintaining performance and functionality.

Superiority of Limestone

The procurement of raw materials for petroleum-based resins involves the fractional distillation of crude oil, naphtha, and the polymerization of monomers. This process significantly impacts climate change due to the energy consumed during heating. In contrast, LIMEX™’s primary raw material, calcium carbonate, is obtained by simply crushing limestone.

This method can slash CO2 emissions by up to 50 times compared to the production of petroleum-based resins. Moreover, limestone mining and processing are less complex than those of petroleum and metals. Limestone’s physical properties are also more resilient, making it less susceptible to environmental degradation from elements like sunlight, which can weaken plastics and rubbers. Given its global abundance, limestone boasts remarkable supply stability and cost-effectiveness.
