<h2>Product Overview</h2> <p>As a dedicated manufacturer and supplier of advanced chemical solutions, we introduce a high-efficiency liquid carbodiimide hydrolysis stabilizer engineered for industrial polymer formulations. Designed for bulk production environments, this additive provides seamless integration and uncompromising defense against moisture-induced degradation.</p> <ul> <li>Optimized for polyester-based PU, TPU, CPU, and MPU systems.</li> <li>Liquid state ensures rapid, homogeneous dispersion without excessive shear.</li> <li>Ideal for large-scale adhesive, coating, and flexible polymer manufacturing.</li> </ul> <h2>Product Description</h2> <p>The structural integrity of polyester-based polyurethanes, biodegradable plastics, and advanced adhesives is constantly threatened by moisture and thermal exposure. When ester linkages break down, the resulting chain scission drastically compromises mechanical strength, flexibility, and overall material lifespan. This liquid carbodiimide hydrolysis stabilizer acts as a highly reactive defense mechanism within your polymer matrix. By actively seeking out and neutralizing carboxylic acid end groups generated during the initial stages of hydrolysis, it halts the catalytic degradation cycle in its tracks. Unlike solid alternatives that require extensive milling and prolonged mixing times, this fluid additive flows effortlessly into liquid processing environments, ensuring a homogeneous blend without localized concentration spikes. Whether incorporated into extrusion lines for thermoplastic polyurethanes or blended into high-performance sealants, it preserves the molecular weight of the base polymers. This translates to end-products that maintain their tactile resilience, structural load-bearing capabilities, and aesthetic finish even under the most punishing humid and high-temperature conditions.</p> <h2>Product Specifications</h2> <table border="1" style="border-collapse: collapse; width: 100%; text-align: left;"> <thead> <tr> <th style="padding: 12px; background-color: #f4f4f4; border: 1px solid #ddd;">Parameter</th> <th style="padding: 12px; background-color: #f4f4f4; border: 1px solid #ddd;">Specification</th> </tr> </thead> <tbody> <tr> <td style="padding: 12px; border: 1px solid #ddd;">Product Name</td> <td style="padding: 12px; border: 1px solid #ddd;">Bio-SAH 322</td> </tr> <tr> <td style="padding: 12px; border: 1px solid #ddd;">Product Type</td> <td style="padding: 12px; border: 1px solid #ddd;">Carbodiimide Hydrolysis Stabilizer</td> </tr> <tr> <td style="padding: 12px; border: 1px solid #ddd;">Physical Form</td> <td style="padding: 12px; border: 1px solid #ddd;">Liquid</td> </tr> <tr> <td style="padding: 12px; border: 1px solid #ddd;">Recommended Dosage</td> <td style="padding: 12px; border: 1px solid #ddd;">0.5% – 2.0%</td> </tr> <tr> <td style="padding: 12px; border: 1px solid #ddd;">Applicable Systems</td> <td style="padding: 12px; border: 1px solid #ddd;">Polyester-based polyurethanes (PU, TPU, CPU, MPU), PLA, EVA, adhesives, coatings, and flexible polymers</td> </tr> <tr> <td style="padding: 12px; border: 1px solid #ddd;">Mechanism of Action</td> <td style="padding: 12px; border: 1px solid #ddd;">Reacts with carboxylic acid end groups to form stable N-acylurea linkages</td> </tr> <tr> <td style="padding: 12px; border: 1px solid #ddd;">Storage Conditions</td> <td style="padding: 12px; border: 1px solid #ddd;">Cool, dry, well-ventilated environment; avoid moisture and air exposure; keep tightly sealed after use</td> </tr> </tbody> </table> <h2>Key Features & Highlights</h2> <p>Formulating resilient polymer systems requires additives that do not disrupt the primary manufacturing workflow.

Below, we address the most common inquiries regarding the integration and performance of our liquid carbodiimide stabilizer.</p> <ul> <li> <h3>How does the liquid form impact the curing time of polyurethane adhesives?</h3> <p>The liquid stabilizer is designed to be non-reactive with the primary isocyanate-hydroxyl curing mechanism. It specifically targets carboxylic acids, meaning it will not accelerate or retard your standard curing profiles, allowing for highly predictable production schedules.</p> </li> <li> <h3>Can this stabilizer be used in transparent or optically clear TPU applications?</h3> <p>Yes. Due to its exceptional compatibility and rapid dispersion capabilities, it integrates seamlessly into the polymer matrix without causing phase separation or micro-voids, thereby preserving the optical clarity and light transmission of transparent films and molded parts.</p> </li> <li> <h3>What happens if the recommended dosage of 2.0% is exceeded?</h3> <p>While exceeding the 2.0% threshold provides diminishing returns on hydrolytic stability, it may also begin to slightly plasticize the polymer matrix, potentially altering the hardness or tensile modulus of the final product. We strongly recommend precise dosing within the 0.5% – 2.0% range for an optimal balance of properties.</p> </li> <li> <h3>Is pre-heating required before adding this liquid stabilizer to high-viscosity prepolymers?</h3> <p>No pre-heating is strictly necessary due to its naturally fluid state at room temperature. However, ensuring that both the prepolymer and the stabilizer are at compatible processing temperatures can further expedite homogeneous blending in exceptionally viscous systems.</p> </li> <li> <h3>How does this product perform in biodegradable PLA compared to traditional synthetic polyesters?</h3> <p>In PLA, it functions exceptionally well by neutralizing the lactic acid generated during ambient moisture exposure. This effectively delays the onset of degradation during the product's useful life, extending its functional durability without permanently preventing its ultimate biodegradation in commercial composting facilities.</p> </li> </ul>
