1. Basic Information
- Product Name: Ethylan 324
- Chemical Category: Macromolecular EO/PO block copolymer
- Key Parameters: Molecular weight 5400, EO content 40%, HLB value 8.0
2. Performance Characteristics
- Surface Activity, Dispersion and Wetting:As a standard surfactant in SC formulations, it functions as a co-dispersant and wetting agent. Its unique steric hindrance effect can effectively prevent particle aggregation. When compounded with carboxylate dispersant Agrilan 788, it significantly reduces the viscosity of SC systems, improves dispersion efficiency, and has low foam, without affecting formulation stability.
- Anti-Crystallization and Anti-Layering:It can inhibit crystal growth, prevent SC systems from solidifying and layering, and is especially suitable for high-content SC formulations (such as prometryn 50% SC, imidacloprid 600g/L FS, etc.), ensuring the physical stability of formulations during long-term storage.
- Compatibility in Multiphase Systems:It performs excellently in the SC part of SE formulations and has excellent compatibility with multiphase systems (such as prochloraz 20% + hexaconazole 8% SE), stabilizing the oil-water interface and avoiding phase separation.

4. Application Scenarios
- Pesticide Formulations:
- SC Formulations: Suitable for high-content technical systems (such as chlorothalonil 720g/L SC, diuron 800g/L SC), and an addition amount of 1-2% can achieve efficient dispersion and stability.
- SE Formulations: In SE systems with multiple active ingredients (such as prochloraz + hexaconazole SE), it can stabilize the SC phase and improve the overall compatibility of the formulation.
- Formula Example (15% Pyraclostrobin + 15% Difenoconazole SC):

5. Storage and Packaging
- Packaging Form: Usually packaged in sealed plastic drums or composite bags to prevent moisture absorption from affecting performance.
- Storage Conditions: Store in a cool, dry and ventilated place, avoid high temperatures (flash point >94℃, but still need to stay away from fire sources). The moisture content <0.3% within the shelf life can ensure stable performance.
6. Competitive Advantages
- Compared with traditional EO/PO copolymers, it has more prominent steric hindrance effect, better viscosity reduction and dispersion efficiency;
- The low-foam characteristic reduces foam interference during production and use;
- The compatibility of multiphase systems can meet the development needs of complex formulations (such as SE) and expand application scenarios.
