Bio-SAH 362 Powder is a high-purity monomeric carbodiimide hydrolysis stabilizer engineered to protect condensation polymers from hydrolytic degradation. It effectively reacts with carboxylic end groups to prevent chain scission, ensuring enhanced durability and long-term mechanical performance in demanding industrial applications.
As a premier manufacturer and supplier of advanced polymer additives, we present this high-purity monomeric carbodiimide hydrolysis stabilizer. Designed strictly for demanding industrial applications, it serves as a critical safeguard for condensation polymers against moisture-induced degradation, ensuring your engineered components maintain their structural integrity.
Moisture and thermal stress are the silent destroyers of condensation polymers, relentlessly breaking down molecular chains and compromising the structural integrity of your finished goods. This advanced monomeric carbodiimide hydrolysis stabilizer serves as a vital defensive shield for engineering plastics. When integrated into your polymer matrix, the fine, white crystalline powder disperses seamlessly, actively seeking out and neutralizing the carboxylic acid end groups that trigger the autocatalytic degradation cycle. The tactile consistency of the powder ensures smooth feeding during extrusion, preventing clumping and ensuring uniform distribution throughout the melt without altering the base material's inherent characteristics.
By interrupting the hydrolysis process at its chemical root, this additive dramatically extends the operational lifespan of ester-containing materials. Manufacturers utilizing polyester polyols, polyamides, PET, and PBT will observe a profound difference in the long-term durability of their products. The stabilizer preserves the crucial mechanical properties—such as tensile strength, impact resistance, and elongation—that your clients demand. Instead of facing premature material failure in humid environments, your engineered components will maintain their pristine performance characteristics, ultimately reducing replacement costs, minimizing product recalls, and elevating the perceived value of your entire product line.
Understanding the precise technical specifications of your additives is crucial for formulating high-performance engineering plastics. The following table outlines the exact chemical and physical properties of our monomeric carbodiimide hydrolysis stabilizer. These stringent parameters ensure consistent reactivity, optimal thermal stability during processing, and reliable integration into your existing production lines. From its exact melting point to its exceptional purity levels, every metric is carefully controlled to meet the rigorous demands of advanced polymer manufacturing.

Engineered to deliver uncompromising protection for vulnerable polymer systems, this hydrolysis stabilizer combines rapid reactivity with exceptional processing stability. The unique chemical architecture ensures that it acts precisely when and where degradation begins, offering a multitude of operational advantages for your manufacturing process.
To fully appreciate the transformative impact of this additive on your polymer formulations, it is essential to examine its core performance dimensions. Each aspect has been meticulously optimized to address the specific challenges faced by formulators and compounders in the advanced materials sector.
Formulation accuracy relies heavily on consistent physicochemical data. This stabilizer boasts a purity level exceeding 99.5% and a highly stable melting point of 50-53°C. Its light color and odorless nature guarantee that it will not introduce impurities or negatively impact the aesthetic and structural quality of high-end engineering plastics, ensuring your final product looks and performs exactly as intended.
For research and development engineers, proven efficacy is paramount. The monomeric carbodiimide reacts rapidly with carboxylic end groups generated during degradation, forming a highly stable N-acylurea structure. This completely severs the autocatalytic hydrolysis loop, significantly extending the service life of polymer products operating under severe high-temperature and high-humidity conditions.
Versatility is a key driver for streamlined procurement. This additive exhibits exceptional compatibility across various polycondensates. It is not only ideal for traditional PET, PBT, PA, and polyester polyols but also perfectly suited for polyurethane elastomers (TPU/CPU/MPU), adhesives, coatings, and ester-based lubricants. Its solubility in multiple organic solvents makes it adaptable to diverse production lines.
Addressing the root cause of plastic aging, this stabilizer prevents polymer chain scission and molecular weight reduction. By capping active carboxylic groups, it can even help repair previously compromised polyester and polyurethane matrices, ensuring that the initial strength, toughness, and durability of the material are maintained over the long term, reducing the risk of mechanical failure.
Optimizing manufacturing overhead is crucial for maintaining a competitive edge. The powder form allows for flexible formulation and uniform blending, suitable for direct addition during compounding, extrusion, or synthesis. With a highly efficient recommended dosage of just 0.5% to 2.0%, it delivers substantial performance upgrades at a minimal inclusion rate, offering an outstanding return on investment.
Aligning with modern industrial compliance standards, this product demonstrates excellent thermal stability at standard processing temperatures. It resists volatilization and exudation, contains no volatile organic compounds (VOCs), and produces no toxic byproducts, thereby ensuring a stable extrusion or injection molding process and maintaining a safe, compliant production environment for your workforce.
Selecting the right chemical partner is just as critical as choosing the right formulation. We understand the stringent requirements of large-scale manufacturing and the necessity for absolute consistency batch after batch. Our commitment goes beyond simply supplying an additive; we provide a foundation for your product's reliability and your brand's reputation.
To assist your engineering and procurement teams, we have compiled detailed answers to the most common technical inquiries regarding our monomeric carbodiimide hydrolysis stabilizer.
For maximum dispersion and efficacy, we recommend adding the powder during the compounding or extrusion phase. It can also be integrated directly during polymer synthesis. The fine crystalline structure ensures it melts and blends uniformly within the polymer matrix at standard processing temperatures, preventing localized concentration issues.
Due to its exceptionally high purity (greater than 99.5%) and light color, this additive has a negligible impact on the optical properties of the base polymer. When used within the recommended dosage range of 0.5% to 2.0%, it maintains the clarity, light transmission, and aesthetic finish of transparent engineering plastics.
No, this specific monomeric carbodiimide is insoluble in water and is designed exclusively for solvent-based or melt-processed condensation polymers. Its primary function is to scavenge moisture and reactive acids within hydrophobic polymer matrices like PU, PA, and polyesters, making it unsuitable for aqueous dispersions.
The stabilizer is formulated to be highly compatible with standard processing conditions for engineering plastics. Its specific melting point of 50-53°C allows it to integrate smoothly without requiring significant adjustments to your extruder's temperature profile, screw speed, or cooling rates, ensuring a hassle-free integration.
To preserve its chemical efficacy, the powder must be stored in a cool, dry environment away from direct sunlight and humidity. Because it is designed to react rapidly with moisture and acids, the container must be tightly sealed immediately after each use to prevent premature activation and degradation from atmospheric moisture.
