product advantage
- High-Efficiency Polymerization InhibitionIt exhibits exceptional free radical scavenging activity at ultra-low dosages (50-500 ppm), effectively preventing premature polymerization of acrylic monomers, methacrylic esters, and unsaturated olefins during long-term storage (6-12 months) and cross-border transportation. This significantly reduces product loss and ensures monomer quality stability for downstream manufacturers.
- Broad Applicability & Process AdaptabilityCompatible with a wide range of vinyl monomers (acrylic acid, butyl acrylate, MMA, etc.) and adaptable to diverse working conditions (temperature: -10~60℃, pH: 4-9). It performs reliably in various scenarios such as warehouse storage, sea freight, and high-temperature industrial environments, meeting global customers’ diverse production needs.
- Excellent Compatibility & StabilityChemically stable in dry air and organic media with low volatility, it shows no adverse reactions with common monomers, solvents, or additives (antioxidants, plasticizers). It maintains consistent performance without affecting the transparency, mechanical properties, or processing efficiency of final polymer products.
- Environmental Compliance & Low ToxicityCompliant with international regulations including EU REACH and US TSCA, it features lower toxicity compared to traditional polymerization inhibitors (e.g., hydroquinone derivatives). Minimal residue in end products meets the "green production" requirements of high-end markets, breaking through environmental trade barriers.
- Multifunctional UtilityBeyond polymerization inhibition, it serves as a high-performance antioxidant, anti-wear agent in lubricants, vulcanization accelerator in rubber production, and corrosion inhibitor for metals. This multifunctionality allows it to penetrate multiple industrial sectors, enhancing market competitiveness and customer value.
- Cost-Effective & Easy to UseIts high activity at low concentrations reduces additive costs for customers. Available in powder form, it is soluble in organic solvents and compatible with existing production lines, requiring no equipment modification. The mature synthesis process ensures scalable supply and stable pricing for bulk orders.
