The shelf life of PESA (Polyepoxysuccinic acid) depends on storage conditions and formulation, but here are the general guidelines: 1. Typical Shelf Life Solid (Powder) PESA: 24–36 months (unopened, dry storage). Liquid PESA (Aqueous Solution): 12–18 months (if properly preserved). 2. Factors Affecting Shelf Life Factor Impact Recommendation Moisture Powder may clump or degrade Store in sealed, moisture-proof containers (HDPE bags with desiccant)….
Polyaspartic acid (PASP) is a biodegradable, non-toxic, and eco-friendly polymer used as a scale inhibitor, dispersant, and corrosion inhibitor. Its effectiveness stems from its unique molecular structure and functional groups. Below is a detailed breakdown of its mechanisms and applications. 1. Chemical Structure & Key Functional Groups Molecular Formula: (C₄H₅NO₃)ₙ Structure: Contains carboxyl groups (–COOH) and amide bonds (–CONH–). Forms a helical or…
PASP is a kind of biopolymer materials, of which molecules contains abundant amido bond, carboxyl and other active groups. Amido peptide bond has biological activity and high chemical stability, hard to decompose at high temperature; carboxyl group can be complex with many metal ions in water, which make PASP have high chemical activity in aqueous…
Ceramic Dispersant ceramic dispersant is a salt of anion polymer. It can adsorb on surface of a varieties of minor particles and thus generate static repulsion, resulting in particles’ dispersion and avoiding particles sedimentation and coarse turn-back. Ceramic Dispersant can be used as additives in magnetic materials, electron ceramic, papermaking, alumina ceramic, household ceramic, etc….
PESA is a multivariate scale and corrosion inhibitor with non-phosphor and non-nitrogen, it has good scale inhibition and dispersion for calcium carbonate, calcium sulfate, calcium fluoride and silica scale, with effects better than that of ordinary organophosphines. When built with organophosphates, the synergism effects are obvious. PESA has good biodegradation properties, it can be widely…

Carboxylate-Sulfonate CopolymerKR-2000 is the copolymer of acrylic-acrylate-sulfosate, it is a good scale inhibitor for calcium phosphate, calcium carbonate and other inorganic minerals. KR-2000 can effectively stabilize calcium phosphate in formula containing phosphate. It can also stabilize zinc in formula containing zinc. It can disperse inorganic microparticles without pH influence. Carboxylate-Sulfonate Copolymer is an effective dispersant…
Acrylic Homopolymer is a Low Molecular Weight (LMW) Polyacrylic Acids and their corresponding sodium salts. These products have weight average molecular weights of approximately 2000 and 4500. KR-1000 are highly effective scale inhibitors that can be used industrial water treatment and oil production applications to inhibit the deposition of calcium carbonate, calcium sulfate, barium sulfate,…
EDTA·Na₄ is a widely used chelating agent in water treatment, detergents, textiles, and pharmaceuticals. Proper packaging and storage are critical to maintain its stability and effectiveness. 1. Packaging Requirements (1) Primary Packaging Material: Plastic Bags (HDPE or LDPE-lined) – Most common for industrial-grade EDTA·Na₄. Multi-layer Kraft Paper Bags – With inner polyethylene coating for moisture resistance. Fiber Drums (for…
PESA is a green, biodegradable, and non-phosphorus water treatment chemical with excellent scale inhibition, dispersion, and chelation properties. In the textile printing and dyeing industry, it is primarily used to improve water quality, prevent scaling, and enhance dyeing uniformity. Below are its key applications and benefits: 1. Water Quality Control in Dyeing Processes (1) Prevention of Metal Ion Interference Chelates…
