Import Best Selling Cationic Polyacrylamideâ (Cpam) — Buy in wholesale FOB from Supplier in Hong Kong

Cationic polyacrylamide (CPAM) from Henan Xinhuan Water Treatment Material Co., Ltd. is a linear polymer compound carrying positive charge density along its chain structure. The molecule contains multiple active groups that enable hydrogen bonding and adsorption with negatively charged colloidal particles. This specific CPAM targets wastewater streams rich in organic matter, where negatively charged suspended solids require charge neutralisation prior to settling or dewatering. The polymer functions through a dual mechanism of charge neutralisation and bridging, forming larger floc structures that separate readily from treated water. Typical molecular weight ranges for this grade fall between 6-12 million Daltons, though buyers should confirm the exact value with the supplier.

The backbone consists of acrylamide monomer units with cationic functional groups grafted through copolymerisation, typically using dimethylaminoethyl methacrylate (DMAEMA) or similar quaternary ammonium derivatives. Charge density, expressed as milliequivalents per gram (meq/g), determines the polymer's affinity for anionic substrates; standard CPAM grades range from 1.0 to 5.0 meq/g depending on application severity. Ionicity, the mole percentage of cationic monomer in the polymer chain, directly correlates with flocculation speed under high-turbidity conditions. The solid content of commercial CPAM powder typically measures 88-92% by weight, with the balance comprising residual moisture and trace monomer. Dissolution in water requires controlled agitation to prevent chain entanglement and optimise hydration of hydrophilic groups.

Municipal sewage plants, food processing facilities, pulp and paper mills, and petroleum refineries represent the primary demand segments for this flocculant. In sludge dewatering applications, CPAM improves cake solids concentration in centrifuges and belt filter presses, reducing disposal volumes. The textile and dyeing industry employs it for colour removal and COD reduction in effluent streams. Pharmaceutical and chemical manufacturers use it for clarifying fermentation broths and process water recycling. Buyers should confirm packaging format (typically 25 kg kraft bags with polyethylene liner), minimum order quantity, and Incoterms directly with Henan Xinhuan, as these trade terms are not stated in the available data. The supplier's Hong Kong registration may offer logistical advantages for certain import routes, though buyers should verify actual dispatch location against their stated Zhengzhou address.

Henan Xinhuan Water Treatment Material Co., Ltd. maintains a registered address at No.76, Science Avenue, Zhongyuan District, Zhengzhou, Henan Province, with a Hong Kong corporate presence noted in the listing. The supplier operates within the water treatment chemicals sector, specifically manufacturing polyacrylamide-based flocculants for industrial and municipal wastewater applications. The trust tier assigned to this listing is 'harbor', which constitutes a baseline verification level rather than an advanced assurance status. The response rate registers at 0.00% with zero average response hours recorded, indicating no historical inquiry response data is available to assess communication reliability. Buyers should initiate direct contact to gauge responsiveness and technical support capability before committing to orders.

The company profile does not disclose production capacity, number of manufacturing lines, annual output figures, or specific quality management certifications such as ISO 9001 or ISO 14001. No client references, export destinations, or years in operation are stated in the available data. The listing emphasises the product's chemical functionality, affinity and adsorption mechanisms, without claiming proprietary manufacturing processes or patented polymer architectures. The dual address structure, Zhengzhou and Hong Kong, suggests potential for flexible trade routing, though buyers must verify which location handles dispatch, customs clearance, and invoicing for their specific transaction. The absence of verified response metrics means due diligence falls entirely to the prospective buyer.
