2. Solid Powder (High Purity Grade)
Appearance: White crystalline powder with active content ≥95% / ≥98%. Convenient for long-distance transportation, suitable for anhydrous systems, high-end polymerization and daily chemical applications.
AMPS Sodium Salt (NaAMPS) is a high-reactivity anionic sulfonate functional monomer, available in 50% aqueous solution and solid powder grades. It features excellent salt tolerance, thermal stability and hydrolysis resistance. Widely copolymerized with acrylamide, acrylic acid, styrene and other monomers to produce polymers for oilfield chemicals, water treatment scale inhibitors, latex coatings, superabsorbent polymers, synthetic fibers and personal care materials.
1. Oilfield Chemicals
- Used to synthesize temperature and salt resistant polyacrylamide. Applied as fluid loss control agent for drilling fluids, thickener for fracturing fluids, EOR flooding agent and oil well cement additive, suitable for high-temperature and high-salinity formations.
2. Water Treatment Chemicals
- Copolymerized with acrylic acid to produce scale inhibitors for suppressing calcium carbonate, calcium sulfate and silica scale. Used in circulating cooling water, reverse osmosis systems, wastewater flocculation and sludge dewatering.
3. Coatings, Emulsions & Adhesives
- Copolymer monomer for styrene-acrylic, pure acrylic and vinyl-acrylic emulsions. Improves film adhesion, scrub resistance and water resistance, and reduces coagulation. Used in water-based adhesives and sealants.
4. Synthetic Fibers
- Third monomer for acrylic fiber to enhance dyeability, whiteness and antistatic property as well as air permeability.
5. Daily Chemicals & Superabsorbent Polymers
- Salt-resistant superabsorbent resins; thickeners and stabilizers for personal care formulations; raw material for hydrogels.
6. Paper Making, Textile Printing & Dyeing
- Retention aids and sizing agents for paper; textile sizes and printing auxiliaries.
Packed in net 25kg packing, 200kg/pallet, 20 pallets in 20"FCL.
Stored in a cool, dry and well-ventilated area. The storage period is 1 year.
