● 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

IntroductionTPU is widely used in hoses, cables, films, footwear, seals, and molded parts because of its flexibility, abrasion resistance, and processing versatility. However, in hot, humid, or water-exposed environments, some TPU grades may gradually lose mechanical strength, surface quality, and l Read More

Recycled PET is becoming more important in the packaging industry as brands look for ways to reduce virgin plastic use and improve sustainability. However, when food-contact applications are involved, the main issue is not only whether rPET is recyclable, but whether it is safe, complian Read More

What is the real difference between low-value recycled PET and premium rPET sheet or film that can run smoothly, form cleanly, and deliver consistent quality? In many plants, the answer is not only raw material sourcing. It is what happens to molecular structure, melt behavior, and process stability Read More
