PASP (Polyaspartic Acid) is a biodegradable, non-toxic, and highly effective green alternative to traditional scale and corrosion inhibitors like phosphonates (HEDP, ATMP) and synthetic polymers (PAA, HPMA). Below are its key advantages: 1. Environmental & Safety Benefits ✅ Fully Biodegradable (>60% in 28 days per OECD 301B) – Unlike persistent phosphonates (HEDP/ATMP). ✅ Non-Toxic (EC50 >100 mg/L for aquatic…
Judging the quality of MBT (2-Mercaptobenzothiazole) products requires evaluating chemical purity, physical properties, performance efficacy, and compliance with industry standards. Below is a comprehensive guide: 1. Chemical Purity & Composition Key Parameters Active Content: High-quality MBT should have ≥ 95% purity (industrial-grade) or ≥ 98% (rubber-grade). Impurities: Free sulfur (should be < 0.5%) Residual solvents (e.g., toluene, cyclohexylamine) Heavy metals (e.g.,…
MA/AA.Na (Maleic Acid/Acrylic Acid Sodium Salt Copolymer) is a versatile water-soluble polymer widely used in industrial water treatment and other applications due to its excellent scale inhibition, dispersancy, and thermal stability. Below are its key application areas and usage guidelines: 1. Industrial Water Treatment (1) Cooling Water Systems Function: Inhibits CaCO₃, Ca₃(PO₄)₂, and CaSO₄ scaling. Dosage: 5–20 mg/L (adjust based…
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)….
