Product Overview

  Polyacrylamide (PAM) is a synthetic water-soluble linear polymer formed by acrylamide polymerization. It is one of the most widely used organic flocculants in the global water treatment industry. According to different ionic properties, PAM is classified into anionic, cationic and nonionic types, each designed for targeted water quality and treatment scenarios.
PAM features long molecular chains and strong adsorption bridging ability. It can capture fine colloidal particles, organic pollutants and suspended solids that inorganic coagulants cannot remove, greatly improving sedimentation speed and effluent clarity. It also shows excellent performance in sludge thickening and dewatering, effectively reducing sludge moisture content and disposal costs.

Key Properties & Advantages

■ Ultra-low dosage:Much lower consumption than traditional inorganic flocculants, greatly saving chemical cost.
■ Fast flocculation & sedimentation:Forms large, dense and stable flocs, significantly improving water treatment efficiency.
■ Complete ionic types:Anionic, cationic and nonionic grades available for all kinds of sewage and sludge conditions.
■ Excellent sludge dewatering effect:Effectively reduces sludge moisture and volume, lowering transportation and disposal costs.
■ Wide adaptability:Stable performance in complex water quality, high salinity and variable pH environments.
■ No secondary pollution:Safe polymer material with stable chemical properties and no toxic residues.

PAM Types & Applications

Types:

■ Cationic Polyacrylamide (CPAM):  Mainly used for municipal sewage sludge dewatering, printing and dyeing wastewater, food wastewater, pharmaceutical wastewater and organic sewage treatment. It efficiently aggregates organic suspended matter and improves solid-liquid separation effect.
■ Anionic Polyacrylamide (APAM): Suitable for industrial inorganic wastewater, mining wastewater, coal washing water, metallurgical wastewater and river water purification. Excellent for turbidity removal and sedimentation acceleration.
■ Nonionic Polyacrylamide (NPAM):Applied for low-temperature and low-turbidity raw water treatment, special industrial wastewater and mineral flotation clarification, performing stably in neutral and weak acidic water systems.

General Industry Applications

  • Municipal Sewage Treatment: Sedimentation aid and sludge dewatering agent.
  • Industrial Wastewater: Printing & dyeing, papermaking, chemical, electroplating, coal washing and mining water treatment.
  • Oilfield Chemicals: Drilling fluid thickener, water plugging agent and EOR auxiliary agent.
  • Papermaking Industry: Retention aid, filter aid and paper strength agent.
  • Construction & Mine: Mortar thickener, sedimentation accelerator and tailings water clarification.

Frequently Asked Questions(FAQ)

1. Q: What would you do to guarantee the product quality?

To fully guarantee stable and reliable product quality, we implement full-process control covering Quality, Health, Safety and Environment (QHSE) with systematic measures,conduct multi-stage product testing with full batch traceability, adopt strict health & environmental control to avoid product contamination, carry out regular QHSE audits and continuous system optimization, plus standardized storage and logistics management. Every link follows unified QHSE rules to eliminate quality risks fundamentally.

Yes, we can provide complete COA, MSDS /TDS documents for your reference prior to placing orders. Please advise the exact product grade and quantity you intend to purchase, and we will send you the latest updated versions of these technical documents promptly by email. All files are issued in accordance with international QHSE standards,for your customs clearance, laboratory testing and internal risk assessment.

We offer flexible and favorable prices for bulk orders. To provide an accurate best quotation,
kindly advise: (1)Required product grade (2)Order quantity (3)Preferred trade term (FOB / CIF) (4)Destination port
Meanwhile, we can supply complete TDS, SDS and COA for your reference before order confirmation. We believe this is an effective way to build long – term business with our customers and earn good reputation.

We support multiple flexible payment terms to meet different cooperation demands:
(1)T/T (Telegraphic Transfer): 30% deposit in advance, 70% balance against copy of Bill of Lading; full T/T in advance for small trial orders.
(2)Irrevocable Letter of Credit at sight (L/C at sight): Acceptable for large bulk orders, issued by reputable international banks.
(3)Negotiable payment terms can be discussed for long-term cooperative clients with stable monthly orders.

Our standard production lead time is 10–15 working days .

(1)For T/T payment: 30% deposit by T/T in advance, balance against scanned BL copy. After your deposit arrives, we will schedule raw material procurement and production immediately within the 10–15 day cycle. This mode safeguards mutual capital safety: the deposit locks exclusive production capacity for you, while you only settle the rest after seeing loading evidence.

(2)For L/C payment: We accept irrevocable sight L/C issued by first-class international banks. The 10–15 working days lead time will start running after we receive and verify the operative L/C text without unachievable clauses. A formal L/C serves as bank credit guarantee for both parties, eliminating default risks effectively. We will review L/C terms thoroughly before production to avoid discrepancies and potential financial losses for both sides.

We support shipment from Qingdao Port and Tianjin Port of China; you can choose the loading port as per your actual demand.

Yes, we fully support third-party inspection during container loading. You can appoint your designated inspection agency to attend the whole loading process at our warehouse. Our QHSE team will coordinate all preparation work in advance, including raw batch COA checking, product appearance verification, weight tally, packing integrity supervision and sealing recording.

Yes, we support OEM & private label packaging service for our products. You can provide your customized brand logo, label design, bag/barrel printing artwork and customized packaging specifications. Our production team will arrange tailored packaging according to your design files. For OEM orders, there is a minimum order quantity requirement. You just need to send us complete label drafts in advance, and we will confirm the sample packaging with you formally before mass production. All packaging procedures follow our QHSE management standards to guarantee packaging tightness, safety and neat appearance. We can also attach your exclusive brand information on COA, TDS and SDS documents upon your request.

We are an integrated chemical enterprise combining manufacturing and international trading. Our company holds equity shares in two professional chemical manufacturing plants, which enables us stable, direct supply of core products with full production control under unified QHSE standards. Apart from our self-produced items from affiliated factories, we also cooperate with qualified certified manufacturers to supply a comprehensive range of chemical raw materials to meet clients’ one-stop purchasing demands.

Every opinion matters to us, looking forward to your sincere feedback for improvement, as well as any chances to cooperate with you.
