Bio-SAH ™ 372N
Bio-SAH™
Bio-SAH 372N is a high-performance polycarbodiimide hydrolysis stabilizer designed for a broad spectrum of polymer systems, including engineering plastics and biodegradable polyesters. It is particularly suitable for materials containing ester or amide functional groups, which are prone to hydrolysis under humid, high-temperature, or long-term environmental conditions.
Polymers such as TPU, PET, PBT, PBAT, PLA, PHA, PBS, PTT, and PA are widely used in industrial applications but often suffer from hydrolytic degradation. This degradation results in polymer chain scission, reduced molecular weight, loss of intrinsic viscosity, and deterioration of mechanical properties such as strength and toughness.
Bio-SAH 372N provides an efficient and long-lasting solution by stabilizing these materials against hydrolysis and acid degradation, ensuring consistent performance throughout processing and service life.
Broad compatibility across multiple polymer systems
Effective hydrolysis and acid degradation inhibition
Improves durability and mechanical property retention
Suitable for both engineering plastics and biodegradable materials
Excellent performance under humid and high-temperature conditions
Ideal for compounding and modified material systems
Bio-SAH 372N is widely used in:
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 modified compounds
Automotive, electrical, cable, and outdoor applications
Bio-SAH 372N contains reactive carbodiimide functional groups that react with carboxylic acid end groups formed during hydrolysis. This reaction produces stable N-acylurea linkages, eliminating catalytic degradation sites and preventing further chain scission. By interrupting the hydrolysis cycle, it helps maintain molecular integrity and long-term material performance.
Recommended dosage: typically 0.5% – 2.5% depending on polymer system
Can be added during compounding, extrusion, or injection molding
Suitable for standard processing conditions of engineering plastics
Store in a cool, dry environment and avoid moisture exposure. Keep packaging tightly sealed. Follow standard industrial safety procedures.
