White corundum F220 WFA powder for Moving Sand Art Liquid Motion
White corundum F220 WFA powder is specially customized for moving sand art and liquid motion sand painting creation.With uniform F220 particle size, high roundness and excellent fluidity, it ensures slow, smooth and layered sand sinking in liquid.It features high whiteness, pure texture, acid and alkali resistance, and stable physical properties, without fading or precipitating impurities in long-term liquid soaking.Superior hardness and wear resistance prevent particle crushing, maintaining stable flow effect for long-term viewing.This white fused alumina powder is the core filling material for dynamic sand art bottles, helping create natural three-dimensional landscape changes and delicate visual effects.
Advantages of White corundum F220 WFA powder for Moving Sand Art Liquid Motion:
- Pure, free of impurities, the purity of Alumina more than 99.5%.
- No damage to the skin, no metal or heavy metal residue.
- The color is pure white, which can brighten the skin tone.
- The particles are highly uniform, small and soft.
- High specific gravity, easy to clean.
