Import Decolorant Polymer — Buy in Bulk from Supplier in China

The decolorant polymer from Wuxi Lansen Chemicals Co., Ltd is a specialist treatment agent engineered for color removal in high-colority wastewater streams, particularly those generated by dyestuff manufacturing and textile finishing facilities. It achieves rapid flocculation and sedimentation of soluble dyes and pigments, reducing color load by adsorption and coagulation mechanisms. The product is supplied as a free-flowing powder with a bulk density of 0.5 to 0.7 g/cm³, suitable for direct dosing into existing effluent treatment systems.

Formulated from cross-linked polystyrene or acrylic-based resins, this polymer offers a high surface area for dye adsorption, with a typical pore volume of 0.8 to 1.2 cm³/g and a mesh size range of 20 to 60 for granular variants. It operates effectively across a pH range of 2 to 10, making it compatible with most industrial wastewater conditions. Standard industry grades for such polymers include a minimum decolorization rate of 85% for reactive dyes and a residual color below 50 Pt-Co units after treatment.

Industries such as textiles, paper, and food processing use this polymer to meet discharge regulations for COD, BOD, and color. It is also employed in tertiary treatment stages where biological processes fail to remove persistent color. Buyers typically source it in 25 kg woven bags with polyethylene liners, and bulk shipments are palletized for export. The product is classified under HS code 3903.90 for customs purposes, with origin documentation issued from Yixing, Jiangsu.

Wuxi Lansen Chemicals Co., Ltd operates from Yixing, Jiangsu, with its registered office at Rm No18, 4th Floor, Modern Life Square, 118 South Jiubin Road. The company is classified as an imported-tier supplier, indicating it sources raw materials or intermediates from overseas for local processing or distribution. Its profile shows a harbor trust tier, which reflects a baseline level of verification for export readiness.

The supplier’s response metrics currently show a 0% response rate, with no recorded average response time. This suggests that inquiries may require follow-up through alternative channels. The company focuses on chemical intermediates and specialty additives, with decolorant polymers as part of its wastewater treatment portfolio.
