What are the advantages of PASP?

Posted on By admin No Comments on What are the advantages of PASP?

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…

How to judge the quality of MBT products

Posted on By admin No Comments on How to judge the quality of MBT products

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.,…
