When you buy SAP, manufacturers ask: what mesh size do you need? They are asking about particle size. Particle size directly determines what your final product ends up looking like.
Coarse granules (around 2 to 3 mm) expand into large, visible beads after absorbing water. They suit agricultural water retention agents – they are not easily washed away in soil – and also decorative products such as crystal soil and artificial snow.
Medium granules (0.5 to 1 mm) offer a balanced absorption speed and ratio, making them the mainstream choice for ice packs, absorbent pads, and cat litter absorbent powder, and they are easy to handle during filling.
Fine powder (several hundred microns or below) has a large surface area and absorbs fast, but it tends to clump. It suits products that require even distribution, such as diaper cores and sanitary pads, or for blending with other powders.
Choosing the wrong particle size means reworking your entire downstream process, so always ask for samples before ordering. Zhengzhou Florel New Materials produces the whole chain from base powder to finished goods, in both coarse and fine grades. Tell us what product you are making, and we will help you pick the right particle size so you do not take detours.
