Import Best Selling Polyacrylamide (Pam) — Buy in wholesale FOB from Supplier in Hong Kong

Henan Xinhuan Water Treatment Material Co., Ltd. supplies polyacrylamide (PAM), a water-soluble polymer that remains insoluble in most organic solvents and delivers effective flocculation across industrial wastewater and municipal treatment applications. The material is categorised into three ionic forms: anionic, cationic and nonionic, each selected according to the charge demand of the suspended solids in the target water matrix. In neutral to alkaline media, PAM behaves as a polyelectrolyte with sensitivity to salt electrolytes, and it forms insoluble gels when crosslinked with high-valent metal ions such as aluminium or iron species.

The polymer backbone of PAM is built from acrylamide monomer units, with ionic character introduced through copolymerisation or post-hydrolysis to yield the anionic and cationic grades. Anionic PAM typically carries carboxylate groups and is favoured for treating inorganic suspensions and mineral-laden effluents; cationic PAM, bearing quaternary ammonium groups, attaches effectively to negatively charged organic solids such as cellulosic or proteinaceous matter. Nonionic PAM, lacking charged substituents, performs where minimal ion interference is required. Molecular weight ranges from several million to over ten million Daltons depending on grade, directly influencing bridging efficiency and dosage rates. Standard industrial grades are supplied as free-flowing white granules or powders with dissolution times that vary by ionic type and temperature.

Primary buyers include municipal water treatment authorities, industrial effluent plants, paper mills, textile dye houses, oilfield service companies and mining operations that require solid-liquid separation or sludge dewatering. The supplier's Hong Kong registered presence with operations in Henan province positions it within China's main chemical manufacturing corridor. Importers should confirm the specific ionic grade, molecular weight band and charge density required for their water chemistry, as these parameters determine dosage and performance. Packaging, MOQ and lead time are not stated in the listing and must be verified directly with the supplier before issuing a purchase order.

Henan Xinhuan Water Treatment Material Co., Ltd. maintains its registered address at No.76, Science Avenue, Zhongyuan District, Zhengzhou, within Henan province, and holds its corporate registration in Hong Kong. The supplier carries a 'harbor' trust tier classification and currently shows a 0.00% response rate with zero average response hours recorded, which indicates no recent inquiry activity or engagement data is available through the platform profile. Buyers should treat this as a signal to initiate direct contact and assess responsiveness before relying on this channel for time-sensitive procurement.

The company profile does not disclose factory certifications, audited production capacity, year of establishment, registered capital, or named clients. No ISO, SGS or third-party verification badges are mentioned in the extracted data. The listing focuses solely on the polyacrylamide product line without reference to complementary water treatment chemicals or after-sales technical support. Importers are advised to request a company brochure, manufacturing licence and quality management certificates during initial due diligence to supplement the limited public information available.
