Sinanox® HSA-2NA

disodium hydroxy(sulfonato)acetate, blancolen HP alternative,SAP raw 原料组分,anti-yellowing agent

Sinanox® HSA-2NA is a sulfonate derivative primarily used as a high-performance 还原剂 and anti-yellowing agent. It effectively retards and inhibits yellowing in polymers (especially in aqueous systems) caused by oxygen, residual monomers (e.g., acrylic acid), or thermal processing. It also enhances reaction activity and reduces monomer residues.
