Bio-SAH™ 342Liquid
Bio-SAH™
Chemical Component: Polymeric Carbodiimide
CAS NO.: 197098-60-5
Appearance: Light yellow transparent liquid
Viscosity: 1000-6000mPa.s(25°C)
Carbodiimide Content: ≥ 6%
Solubility: Soluble in polyester polyols, most organic solvents and water.
Application area and performance: The utility model relates to a liquid polymeric carbodiimide anti-hydrolysis stabilizer, liquid type, easy to add, good compatibility with materials, soluble in water.
Widely used in sole liquid, PBAT, PLA and adhesive. As a hydrolytic stabilizer for polyurethane, biodegradable plastics and adhesives.
Synthetic resins, especially polyurethane resins, can be susceptible to hydrolysis, which can degrade the material over time. To counteract hydrolysis in polyurethane synthetic resins, several anti-hydrolysis agents can be considered. Here are some types of additives commonly used:
Stabilizers and Antioxidants: Hindered phenols, phosphites, and other antioxidant compounds are often used to stabilize polyurethane resins against oxidative degradation, including hydrolysis.
Isocyanate Blocking Agents: As with polyurethane polyols, blocking agents can be used to protect isocyanate groups from moisture, preventing hydrolysis. Common blocking agents include phenols or alcohols.
Silane Coupling Agents: Silane-based additives can enhance the moisture resistance of polyurethane resins by improving the adhesion between the resin matrix and fillers or reinforcing materials.
Polyol Modification: Modifying polyol structures by incorporating hydrophobic segments can enhance the overall resistance of polyurethane resins to hydrolysis.
Antimicrobial Agents: In some cases, incorporating antimicrobial agents into polyurethane formulations not only prevents microbial growth but also indirectly protects against hydrolysis associated with microbial activity.
When choosing an anti-hydrolysis agent for polyurethane synthetic resins, it's important to consider factors such as the resin's composition, processing conditions, and the specific application requirements. Compatibility with other additives and potential interactions with the resin matrix should also be evaluated. As with any formulation modification, manufacturers typically conduct stability and performance tests to ensure that the selected anti-hydrolysis agents effectively mitigate hydrolysis without compromising other essential properties of the synthetic resin. Regulatory compliance and safety considerations are also important aspects of the selection process.
