Ultra-high purity monomeric molecular structure: The main component is high-purity N,N'-Di(2,6-diisopropylphenyl)carbodiimide with a purity of ≥99.5%, no impurity residue. It appears as white or off-white crystalline powder with light color, no pungent odor, and will not affect the appearance and sensory properties of finished products.
Excellent thermal stability and reaction activity: Its melting point is stable at 50~53℃, which is suitable for high-temperature processing of various materials, with no decomposition, no volatilization and no yellowing during processing. The high-activity carbodiimide functional groups can accurately capture and block the active terminal carboxyl groups in the polymer system, with high reaction efficiency and strong directivity.
Excellent solubility and compatibility: Soluble in a variety of organic solvents, insoluble in water. It has excellent compatibility with polyester polyol, polyurethane, polyester, polyamide and other polymer systems, with no precipitation, no agglomeration, and will not affect the original processing fluidity and molding performance of materials.
Long-term anti-hydrolysis protection: It can fundamentally block the autocatalytic hydrolysis chain reaction caused by terminal carboxyl groups, effectively inhibit the hydrolysis and acidolysis aging of materials, stabilize the initial mechanical properties of materials, and greatly extend the service life of products under harsh working conditions such as high temperature and humidity.
Easy processing and storage: Crystalline powder form, easy to add and disperse, no complex pretreatment required, and compatible with existing automated production processes. It has excellent storage stability under sealed conditions, with long-term non-decay of performance.
