Bio-SAH 362 Powder is a representative monomeric carbodiimide-based hydrolysis stabilizer developed for condensation polymers and engineering plastics. Materials such as polyester polyols, polyamide (PA), PET, and PBT are widely used in industrial applications due to their excellent mechanical and thermal properties. However, these materials are inherently susceptible to hydrolysis because of the presence of ester or amide functional groups in their molecular structure.
Hydrolysis is a common and critical issue in engineering applications, especially under conditions of moisture, heat, and long-term environmental exposure. It leads to chain scission, reduced molecular weight, and deterioration of mechanical properties such as strength, toughness, and durability.
Bio-SAH 362 Powder provides an effective solution by offering high reactivity and purity. As a monomeric carbodiimide, it reacts rapidly with carboxylic acid end groups formed during degradation, thereby interrupting the hydrolysis cycle and stabilizing the polymer structure.
Monomeric carbodiimide with high purity and strong reactivity
Excellent hydrolysis resistance for condensation polymers
Improves long-term durability and mechanical performance
Effective in polyester polyols, PA, PET, and PBT systems
Suitable for ester-containing engineering materials
Powder form for flexible formulation and easy incorporation
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 sites responsible for further degradation. By breaking the autocatalytic cycle, the additive preserves molecular weight, mechanical properties, and overall performance of the material over time.
Recommended dosage: typically 0.5% – 2.0% depending on polymer system
Can be added during compounding, extrusion, or polymer synthesis
Suitable for standard processing conditions of engineering plastics
Store in a cool, dry place and avoid exposure to moisture. Keep container tightly sealed after use. Follow standard industrial safety procedures.
