The core value of calcium-zinc stabilizers in the production of rigid wall panels is reflected in three aspects: first, ensuring processing stability, avoiding machine blockage and roller sticking caused by material degradation, reducing the rejection rate and improving production efficiency; second, improving product quality, optimizing material fluidity, ensuring the wall panels have a smooth surface and uniform color, enhancing the toughness and strength of the wall panels and extending their service life; third, meeting environmental compliance requirements, containing no heavy metals, complying with domestic and foreign environmental standards, and helping enterprises break through environmental barriers and expand the high-end market.
