<h2>Product Overview</h2> <p>As a premier manufacturer and global supplier of advanced polymer additives, we introduce a high-performance polycarbodiimide hydrolysis stabilizer engineered for demanding industrial applications. This specialized compound mitigates hydrolytic degradation in moisture-sensitive plastics, ensuring structural integrity during commercial-scale manufacturing.</p> <ul> <li>Engineered specifically for ester and amide-functionalized polymer systems</li> <li>Effectively prevents chain scission and molecular weight reduction</li> <li>Optimized for seamless integration into high-volume extrusion and injection molding</li> <li>Enhances the durability of both traditional plastics and modern biodegradable materials</li> </ul> <h2>Product Description</h2> <p>Polymers containing ester or amide functional groups inherently suffer from hydrolytic degradation when subjected to humid environments, elevated temperatures, or prolonged environmental exposure. This degradation manifests as polymer chain scission, a drastic reduction in molecular weight, loss of intrinsic viscosity, and the ultimate deterioration of mechanical properties such as tensile strength and impact toughness. Our advanced polycarbodiimide hydrolysis stabilizer acts as a highly reactive scavenger, seamlessly blending into the polymer matrix during the melt phase. Visually presenting as a uniform, free-flowing additive, it melts cleanly without altering the base polymer's optical clarity, color profile, or surface finish, while maintaining an odorless profile during high-temperature processing.</p> <p>By introducing this stabilizer into the compounding phase, production facilities can effectively neutralize the carboxylic acid end groups that catalyze the degradation process. The resulting chemical interaction forms highly stable N-acylurea linkages, fundamentally halting the hydrolysis cycle. This ensures that the final molded or extruded components maintain their structural resilience and dimensional stability over an extended service life. Whether integrated into traditional engineering plastics or modern biodegradable polyesters, this stabilizing agent provides a robust defense against moisture-induced failure, safeguarding the intrinsic value of the end product.</p> <h2>Product Specifications</h2> <table border="1" style="border-collapse: collapse; width: 100%; text-align: left;"> <thead> <tr> <th style="padding: 8px; background-color: #f2f2f2;">Specification Category</th> <th style="padding: 8px; background-color: #f2f2f2;">Details</th> </tr> </thead> <tbody> <tr> <td style="padding: 8px;"><strong>Product Name</strong></td> <td style="padding: 8px;">Bio-SAH 372N Polycarbodiimide Hydrolysis Stabilizer</td> </tr> <tr> <td style="padding: 8px;"><strong>Model</strong></td> <td style="padding: 8px;">Bio-SAH™ 372N</td> </tr> <tr> <td style="padding: 8px;"><strong>Brand</strong></td> <td style="padding: 8px;">Bio-SAH™</td> </tr> <tr> <td style="padding: 8px;"><strong>Chemical Composition</strong></td> <td style="padding: 8px;">Polycarbodiimide</td> </tr> <tr> <td style="padding: 8px;"><strong>Recommended Dosage</strong></td> <td style="padding: 8px;">0.5% – 2.5% (depending on polymer system)</td> </tr> <tr> <td style="padding: 8px;"><strong>Compatible Polymers</strong></td> <td style="padding: 8px;">TPU, PET, PBT, PBAT, PLA, PHA, PBS, PTT, PA (Nylon)</td> </tr> <tr> <td style="padding: 8px;"><strong>Processing Methods</strong></td> <td style="padding: 8px;">Compounding, Extrusion, Injection Molding</td> </tr> <tr> <td style="padding: 8px;"><strong>Storage Conditions</strong></td> <td style="padding: 8px;">Cool, dry environment, tightly sealed, avoid moisture exposure</td> </tr> </tbody> </table> <h2>Key Features & Highlights</h2> <p>Integrating this advanced stabilizer into your production line offers immediate improvements in material longevity and processing stability.

When moisture infiltrates a polymer matrix, it cleaves ester or amide bonds, generating carboxylic acid and hydroxyl end groups. The newly formed acid acts as a catalyst, exponentially accelerating further degradation.</p> <h3>Targeted Molecular Capture</h3> <p>The active functional groups act like molecular magnets, instantly identifying and binding to rogue carboxylic acid end groups the moment they form within the polymer matrix.</p> <h3>Permanent Linkage Generation</h3> <p>The chemical reaction between the carbodiimide and the acid yields a permanent, highly stable N-acylurea linkage. This new bond effectively caps the broken polymer chain, preventing further unraveling.</p> <h3>Catalytic Deactivation</h3> <p>By aggressively consuming the acidic byproducts of initial moisture exposure, the stabilizer completely removes the autocatalytic trigger, instantly halting the vicious cycle of hydrolytic breakdown.</p> <h3>Molecular Weight Preservation</h3> <p>Capping the polymer chains locks the molecular weight in place. This ensures the material continues to behave predictably under physical stress, maintaining its original design specifications.</p> <h2>Broad Compatibility</h2> <p>Formulating polymer blends often requires navigating complex chemical interactions.

Below, our engineering team addresses the most common inquiries regarding the integration, performance, and handling of our polycarbodiimide technology.</p> <h3>How does this stabilizer interact with existing UV absorbers or antioxidants in a polymer blend?</h3> <p>It exhibits excellent synergistic compatibility with most standard hindered amine light stabilizers (HALS) and phenolic antioxidants. It does not interfere with their free-radical scavenging mechanisms, allowing formulators to build comprehensive, multi-factor protection systems without chemical conflicts.</p> <h3>Can this additive be used in transparent or optically clear polymer applications?</h3> <p>Yes. When processed correctly at the recommended dosage levels, the stabilizer melts cleanly and disperses uniformly at the molecular level. It seamlessly integrates into the matrix, preserving the pristine optical clarity and high light transmission properties of resins like PET and transparent TPU.</p> <h3>What is the impact of this stabilizer on the melt flow index (MFI) during extrusion?</h3> <p>By preventing chain scission, it effectively stabilizes the melt flow index. Without it, hydrolysis would cause a sharp increase in MFI due to lowered molecular weight. The stabilizer ensures the MFI remains consistent with the virgin polymer's baseline, preventing unpredictable flow behavior in the mold.</p> <h3>Is it necessary to pre-dry the stabilizer before compounding?</h3> <p>While the stabilizer itself is packaged in advanced moisture-barrier containers, it is highly reactive to water. It should never be pre-dried in the same hopper as wet resin, as it will prematurely react with the evaporating moisture. It is best fed directly into the melt zone or mixed with thoroughly pre-dried polymer pellets immediately before processing.</p> <h3>How do I determine the exact dosage rate for my specific biodegradable polymer?</h3> <p>The optimal dosage depends on the initial moisture content, processing temperature, and the expected service life of the final product. We generally recommend starting at a 1.0% addition rate for sensitive materials like PLA or PBAT, and adjusting based on accelerated aging test results. Our technical support team is readily available to assist with custom dosage profiling.</p>
