Messi Biology Co., Ltd. states that in modern society, sports and health have become an essential part of people’s lives. Whether for professional athletes’ training and competition or for general fitness in a gym, a safe, comfortable, and durable flooring environment is crucial. Polyvinyl chloride (PVC) sports flooring has become the preferred choice for venues due to its excellent elasticity, rich colors, and easy maintenance. However, not all PVC flooring is created equal. The difference between high-end and ordinary products often lies in “invisible” formulation details, where magnesium carbonate, as a key functional filler, plays a core role in providing “invisible protection.”
In the production formulation of PVC flooring, fillers are an indispensable component, primarily serving to increase volume and reduce cost. However, magnesium carbonate’s role extends far beyond this; it is a functional reinforcing filler. While ordinary flooring might use inexpensive calcium carbonate (CaCO₃), high-end flooring opts for magnesium carbonate, which offers superior performance. This is because magnesium carbonate brings a series of crucial performance enhancements:
First, enhanced density and wear resistance. The addition of magnesium carbonate significantly increases the flooring’s unit area mass (i.e., surface density), making its texture denser and heavier. This not only improves underfoot stability but also greatly enhances the surface’s abrasion resistance, extending the service life of the flooring under frequent foot traffic and high-intensity exercise.
Second, excellent anti-slip performance. The microscopic morphology of magnesium carbonate particles can effectively increase the friction coefficient of the flooring surface. Whether exercising in shoes or practicing yoga barefoot, it provides a stable grip, effectively preventing the risk of sports injuries caused by slipping. Its contribution to safety is immeasurable.
Third, improved dimensional stability and heat resistance. PVC is a thermoplastic material prone to thermal expansion and deformation when heated. Magnesium carbonate possesses good thermal stability, effectively reducing the thermal expansion and contraction of the flooring caused by temperature changes during processing and use, ensuring tight seams and preventing curling after installation. At the same time, it can also enhance the flame retardancy rating of the flooring, adding another layer of security for venues.
Applying magnesium carbonate in this context presents significant technical challenges. The primary issue is dispersibility. If filler particles cannot be uniformly dispersed during the PVC plasticization process, they will form stress points, leading to easy cracking and reduced toughness of the flooring. Secondly, there are stringent requirements for whiteness and impurities. Flooring colors are bright and vibrant; if the filler itself has insufficient whiteness or contains colored impurities, it will severely affect the purity of the finished product’s color. Finally, particle morphology and size are critical. Sharp, rough particles can accelerate wear and tear on production equipment, while optimized micron-sized spherical or platy (flake-like) particles can achieve better reinforcing and toughening effects within the system.
To address these pain points, Messi Biology Co., Ltd. has launched ultra-fine active magnesium carbonate treated with surface modification. Through advanced surface activation technology, the company coats magnesium carbonate particles with a layer of coupling agent. This “coating” greatly improves the compatibility and bonding force between magnesium carbonate and PVC polymer chains, allowing it to disperse uniformly and firmly within the PVC matrix, much like sand blending into cement. It no longer agglomerates or precipitates, thus fully exerting its reinforcing and toughening effects. The product boasts extremely low content of coloring impurities like iron and manganese, ensuring bright and pure colors for the flooring. Its specific particle size distribution provides optimal filling, and while increasing density, it still maintains the excellent elasticity characteristic of PVC flooring, achieving a perfect balance between durability and comfort.
Therefore, when we enjoy sports in high-end gymnasiums or fitness centers, the bright, elastic, and safe anti-slip flooring beneath our feet is silently supported by Messi Biology Co., Ltd.’s high-performance magnesium carbonate, providing robust “invisible protection” and safeguarding the health and safety of every athlete.
