Product Overview
AMPS, short for 2-Acrylamido-2-methylpropane sulfonic acid, Alias: ATBS, CAS No.:15214-89-8, EINECS No.: 258-321-1. It is a reactive water-soluble acrylic monomer with sulfonic acid functional groups. Its unique molecular structure endows polymers with permanent anionic charge, excellent anti-hydrolysis performance, high temperature resistance and strong anti-salt capability compared with common acrylamide polymers.
AMPS can undergo homopolymerization or copolymerize with acrylamide, acrylic acid, acrylonitrile and other vinyl monomers to produce multifunctional water-soluble polymers. It serves as a key raw material for manufacturing scale inhibitors, dispersants, drilling fluid additives, thickeners and superabsorbent resins.

Key Properties & Advantages
■ Excellent thermal stability and high salt resistance, suitable for high-temperature and high-salinity working environments
■ Superior hydrolytic stability under acidic, neutral and weakly alkaline conditions
■ Strong hydrophilicity and anionic characteristics, improving polymer dispersion and adsorption capacity
■ Good copolymerization activity with various acrylic monomers
■ Low residual impurities, stable quality for long-term polymer synthesis
Main Applications
■ Oilfield Chemicals: AMPS-based polymers are used in water-based drilling fluids, fracturing fluids, cementing additives and EOR polymer flooding. They act as fluid loss control agents, clay inhibitors and friction reducers to stabilize wellbore under HT/HS (high temperature high salinity) reservoir conditions.
■ Industrial Water Treatment: AMPS copolymers are mainstream scale inhibitors and dispersants for circulating cooling water, boiler water and wastewater treatment. Effectively suppress calcium carbonate, calcium sulfate and phosphate scale; disperse suspended solids and sludge.
■ Superabsorbent Polymers (SAP): Improve salt absorbency of SAP used in hygiene products, agricultural water retention agents and industrial gel materials.
■ Textile & Printing Auxiliaries: Modify acrylic fiber; enhance dye uptake, antistatic property and washing fastness for synthetic fabrics.
■ Coatings, Adhesives & Construction Chemicals: Applied in waterborne latex coatings, pressure-sensitive adhesives and concrete superplasticizers to boost dispersion stability, adhesion strength and workability.
■ Other Fields:Papermaking retention aids, daily chemical thickeners, medical hydrogels and biomaterial intermediates.

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.
2. Q:Can you provide COA / MSDS /TDS before order?
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.
3. Q: What about your price?
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.
4. Q: What payment terms do you accept?
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.
5. Q:What about the order lead time?
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.
6. Q:Which ports can you ship from?
We support shipment from Qingdao Port and Tianjin Port of China; you can choose the loading port as per your actual demand.
7. Q:Can you arrange thirty party inspection during loading?
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.
8. Q:Do you accept OEM packaging (private label)?
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.
9. Q: Are you manufacturer or trading company?
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.
