Bio-SAH 372N is a high-performance polycarbodiimide hydrolysis stabilizer developed for blended and modified polymer systems. It is particularly effective in improving the hydrolytic stability of polymers containing ester or amide linkages, which are highly sensitive to moisture, heat, and long-term environmental exposure.
In many applications such as engineering plastics, elastomers, and biodegradable materials, hydrolysis leads to chain scission, reduction in molecular weight, and deterioration of mechanical properties. Bio-SAH 372N offers a reliable and long-lasting solution by chemically neutralizing degradation-active species and stabilizing polymer structures during both processing and service life.
Excellent hydrolysis resistance across multiple polymer systems
High thermal stability suitable for high-temperature processing
Long-term stabilization performance (non-migrating, durable effect)
Effective in both engineering plastics and biodegradable materials
Good compatibility with a wide range of resins
Suitable for compounding and modification applications
Bio-SAH 372N is widely used in various polymer systems, especially in modified and blended materials:
Thermoplastic Polyurethane (TPU)
Polyester resins such as PET, PBT, and PTT
Biodegradable polymers including PBAT, PLA, PHA, and PBS
Polyamide (PA, Nylon) engineering plastics
Polymer blends and alloy systems requiring long-term durability
Automotive, electrical, cable, and outdoor applications
Bio-SAH 372N contains reactive carbodiimide functional groups that selectively react with carboxylic acid end groups formed during hydrolysis. This reaction produces stable N-acylurea structures, effectively eliminating the catalytic sites responsible for further degradation. By interrupting the autocatalytic hydrolysis cycle, the additive maintains molecular weight, mechanical strength, and overall material performance over extended periods.
Recommended dosage: typically 0.5% – 2.5% depending on polymer system and performance requirements
Can be added during extrusion, compounding, or injection molding
Suitable for high-temperature processing conditions
Store in a dry, cool place and avoid moisture exposure. Keep container tightly sealed. Follow standard industrial handling procedures.
