Import Calcium Lignosulfonate — Buy in Bulk from Supplier in China

Calcium lignosulfonate supplied by Shenyang Xingzhenghe Chemical Co., Ltd. is a light‑yellow powder obtained from the lignin component of wood. The product is characterised by a measured pH of 5.5, a moisture content of 5.36 % and a total reducing matter of 3.51 %. These figures are taken directly from the supplier’s data sheet and confirm its suitability for chemical processes that require a mildly acidic additive. The material complies with ISO and SGS testing protocols as noted by the supplier.

In the lignosulfonate market the typical molecular weight lies between 10 kDa and 30 kDa, providing strong binding and dispersing action. Standard solubility exceeds 100 g L⁻¹ at 25 °C, and typical purity is above 90 % as measured by dry‑basis analysis. Bulk density is usually in the range of 0.5‑0.8 g cm⁻³, while particle size distribution commonly falls between 100 µm and 200 µm. These industry‑wide parameters help buyers compare grades from different manufacturers.

The additive is widely used as a concrete admixture to improve workability and durability, as a dispersant in agricultural formulations, and as a binder in animal‑feed pellets.
