Bio-SAH 362 Powder is a high-performance hydrolysis stabilizer in white crystalline powder form, based on monomeric carbodiimide chemistry. It is specifically designed for condensation polymers and engineering plastics that are susceptible to hydrolysis due to ester or amide functional groups in their molecular structure.
Materials such as polyester polyols, polyamide (PA), PET, and PBT are widely used in industrial and engineering applications. However, under conditions of moisture, heat, and long-term environmental exposure, these materials tend to undergo hydrolytic degradation. This leads to chain scission, reduced molecular weight, loss of intrinsic viscosity (IV), and deterioration of mechanical properties such as strength, toughness, and durability.
Bio-SAH 362 Powder provides an effective and reliable solution by combining high purity with strong reactivity. As a monomeric carbodiimide, it reacts rapidly with carboxylic acid end groups formed during hydrolysis, interrupting the degradation cycle and stabilizing the polymer structure.
White crystalline powder for high purity and clean formulation
Monomeric carbodiimide with fast and efficient reactivity
Excellent hydrolysis resistance for condensation polymers
Improves long-term durability and mechanical performance
Maintains molecular weight and intrinsic viscosity (IV)
Suitable for polyester polyols, PA, PET, and PBT systems
Easy handling and good dispersion in processing
Bio-SAH 362 Powder is widely used in:
Polyester polyols for polyurethane systems
Polyamide (PA, Nylon) engineering plastics
Polyester resins such as PET and PBT
Engineering plastics and modified compounds
Applications exposed to humidity, heat, and long-term service conditions
The monomeric carbodiimide functional groups in Bio-SAH 362 react efficiently with carboxylic acid end groups generated during hydrolysis. This reaction forms stable N-acylurea structures, eliminating catalytic degradation sites and preventing further chain scission. As a result, the additive effectively preserves molecular integrity and ensures long-term performance.
Recommended dosage: typically 0.5% – 2.0% depending on system requirements
