Bio-SAH™ 322Liquid is an innovative liquid carbodiimide-based additive designed to protect ester-based polymers from hydrolysis degradation. As a high-performance plastic additive and polyurethane stabilizer, it significantly extends the service life of materials exposed to moisture, heat, and harsh environmental conditions.
Superior Hydrolysis Protection
Reacts with carboxyl end groups to prevent polymer chain scission.
Maintains mechanical properties in high-humidity environments (up to 85% RH).
Liquid Formulation Advantages
Ensures easy handling and uniform dispersion without dust generation.
Compatible with automated dosing systems for precise addition.
Excellent Thermal Stability
Effective at processing temperatures up to 250°C.
Suitable for high-temperature applications like engineering plastics.
Broad Material Compatibility
Works with PU, PET, PLA, PBAT, and other polyesters.
Effective in both biodegradable and conventional plastics.
Eco-Friendly Formula
Contains bio-based components.
Complies with REACH, RoHS, and FDA regulations.
Hydrolysis Prevention: Blocks moisture-induced degradation in ester groups.
Mechanical Property Preservation: Maintains tensile strength and elongation.
Process Stability: Reduces viscosity variation during processing.
Extended Product Lifespan: Enhances durability in demanding conditions.
Bio-SAH™ 322Liquid is a clear to pale yellow viscous liquid with excellent flow properties. Its low-volatility formula ensures stability during processing, while its non-migrating nature guarantees long-term protection. The additive is odorless and safe for food-contact applications.
Technical Specifications:

Polyurethane Systems
Elastomers: Automotive parts, seals, and gaskets.
Foams: Mattress and insulation materials.
Biodegradable Plastics
PLA/PBAT Films: Compostable packaging and agricultural mulch films.
Engineering Plastics
PET: Bottles, fibers, and industrial components.
PBT: Electrical connectors and automotive parts.
Coatings & Adhesives
Waterborne PU coatings (improves wet adhesion durability).
✅ Easier Processing: Liquid form simplifies incorporation into polymer systems.
✅ Higher Efficiency: Provides better dispersion and more consistent results than powder alternatives.
✅ Long-Term Protection: Continues to function throughout product lifespan.
✅ Versatile Application: Suitable for multiple polymer types and processing methods.
Polyurethanes: 0.5–2% by weight
PET/PLA/PBAT: 0.3–1.5% by weight
Nylon/Engineering Plastics: 1–3% by weight
