● Anti-hydrolysis agent selection should begin with polymer type and hydrolysis mechanism. ● Carbodiimide-based stabilizers are commonly used for polymers containing ester, urethane, or amide groups. ● PET, TPU, PLA, PBAT, PU, PBT, PA, and PC may require different anti-hydrolysis strategies. ● Monomeric and polymeric carbodiimide types may differ in activity, migration tendency, processing behavior, and long-term stability. ● Powder, liquid, emulsion, and masterbatch forms should be matched to the production process. ● The final selection should be confirmed through dosage trials, processing evaluation, and aging tests.

● Anti-hydrolysis performance is influenced by the whole system, not only the additive. ● Moisture content is one of the most important factors affecting hydrolytic degradation. ● Heat, residence time, and processing history can accelerate chain scission and performance loss. ● Acid value and carboxyl end groups can increase hydrolysis risk and affect stabilizer demand. ● Poor dispersion can lead to inconsistent performance even when the correct additive is used. ● Dosage must be validated through testing because too little or too much additive can create problems. ● Real application aging tests are necessary to confirm long-term performance.

● Anti-hydrolysis agent selection should begin with the polymer type and final application. ● Processing degradation and long-term aging require different evaluation methods. ● Moisture level, acid value, and carboxyl end groups are important indicators of hydrolysis risk. ● Powder, liquid, and masterbatch forms should be selected according to the production process. ● Dosage should be validated through testing rather than copied from another polymer system. ● Clear technical information helps suppliers recommend a more suitable solution.

● Powder, liquid, and masterbatch Anti-Hydrolysis Agents can be based on similar carbodiimide chemistry but serve very different industrial processing needs. ● Powder Anti-Hydrolysis Agents are often selected for formulation flexibility, precise dosage control, and broad adaptability across TPU, PET, PLA, PBAT, PU, and polyester polyol systems. ● Liquid Anti-Hydrolysis Agents are commonly used in polyurethane systems, coatings, adhesives, emulsions, and other compatible liquid formulations. ● Masterbatch Anti-Hydrolysis Agents are widely preferred in PET film, BOPET film, PET monofilament, PET injection molding, and other thermoplastic extrusion processes. ● The best choice of Anti-Hydrolysis Agents depends on polymer type, process temperature, feeding method, dispersion requirements, moisture control, and long-term aging targets. ● Production trials and accelerated aging tests are necessary before finalizing the form and dosage of Anti-Hydrolysis Agents.

● Anti-hydrolysis agents, antioxidants, UV absorbers, heat stabilizers, and chain extenders are not interchangeable. ● Anti-hydrolysis agents mainly target moisture- and acid-related hydrolytic degradation. ● Antioxidants mainly help reduce oxidative degradation caused by oxygen, heat, or radicals. ● UV absorbers help improve resistance to light-related aging and outdoor exposure. ● Heat stabilizers support thermal stability during processing or service. ● Chain extenders may help rebuild molecular weight or improve melt strength, but they are not the same as anti-hydrolysis agents. ● The right additive package should be selected according to the actual failure mechanism.

Hydrolysis is a common chemical reaction in which water participates in the breaking of chemical bonds. In industrial materials, polymers, coatings, additives, and chemical intermediates, hydrolysis can lead to performance loss, structural degradation, and shorter service life. Read More

Recycled PET often suffers from chain scission during mechanical recycling and repeated melt processing, which lowers molecular weight, reduces intrinsic viscosity, and weakens melt strength and processability. That is why chain extenders are widely discussed in rPET modification. Read More

IntroductionEVA is widely used in cable insulation and sheathing because of its flexibility, good electrical performance, and processing adaptability. However, in humid, hot, or long-term service environments, EVA cable compounds may still face degradation risks that affect durability and overall pe Read More
