Improving resilience of LVT flooring with ALCAMIZER™

Innovation

01 Oct 2025

PVC Flooring is a category of floor coverings made from PolyVinyl chloride. The flooring has multiple layers (wear layer, decorative film, backing)

LVT (Luxury Vinyl Tile) is a premium type of PVC flooring that mimics natural materials such as wood, stone, or ceramic, with added durability, flexibility, and comfort underfoot.

These types of floors are popular because they are water-resistant, durable against wear and impact, easy to clean, softer and quieter than ceramic or wood.

But during processing (extrusion, calendaring, hot pressing) of PVC flooring the material is exposed to high temperatures (180–200°C). ALCAMIZER™ (hydrotalcite) products play a key role in the thermal stabilization during processing. PVC tends to degrade and releases HCl gas. ALCAMIZER™ products capture and neutralize HCl, preventing chain breakdown. This ensures smooth processing and strong, flexible flooring.

Long-term stability (UV, Heat, Cleaning Chemicals), PVC floors are exposed to sunlight through windows, heat from underfloor systems, and detergents. ALCAMIZER™ products act as an acid scavenger, protecting PVC against yellowing, chalking, and brittleness.

Replacement for toxic stabilizers. Older PVC flooring used lead, barium, or cadmium stabilizers, which are toxic and now banned in most regions. ALCAMIZER™ products are non-toxic, eco-friendly, and REACH/RoHS compliant.

Aesthetic Preservation. LVT relies on a decorative film (wood or stone look) and a clear PVC wear layer. ALCAMIZER™ products help keep the wear layer transparent and non-yellowing, so the design stays sharp and realistic.

Synergy with Other Additives, Flooring formulations also contain, plasticizers (for flexibility), fillers (like CaCO₃ for cost and strength), pigments and TiO₂ (for color and UV resistance). ALCAMIZER™ products improve compatibility and prevent degradation reactions among these additives.
