For chemical procurement managers and R&D scientists, precise product specifications are the cornerstone of successful material selection. When considering flame retardants for polyester (PET) modification, understanding the detailed properties of 2-Carboxyethyl(phenyl)phosphinic acid (CEPPA) is essential. NINGBO INNO PHARMCHEM, a leading supplier and manufacturer of specialty chemicals in China, provides comprehensive technical data for its CEPPA product (CAS 14657-64-8). CEPPA is a high-performance, halogen-free phosphorus flame retardant valued for its reactive nature and effectiveness in PET applications. Key specifications typically include: * Appearance: White powder or crystal. This physical form is crucial for handling and incorporation into polymer matrices. * Purity (HPLC): Typically ≥99.0%. High purity ensures consistent performance and avoids unwanted side reactions during polymerization. * Melting Point: Ranging from 156-161°C. This indicates good thermal stability, vital for melt processing of polyester. * Phosphorus Content (P%): Usually around 14.0-14.5%. The phosphorus content is directly related to the flame-retardant efficacy. * Acid Value: Approximately 522±4 mgKOH/g. This parameter is important for understanding its reactivity and compatibility in formulations. * Moisture Content: ≤0.5% or lower. Low moisture content is critical for melt processing to prevent hydrolytic degradation. * Iron Content (Fe): ≤0.005% or ≤20 ppm. Low metal impurities are important for maintaining product quality and preventing discoloration. * Chloride Content: ≤0.01% or ≤100 ppm. Low chloride levels are standard for high-purity chemical intermediates. These specifications, readily available from NINGBO INNO PHARMCHEM, ensure that manufacturers can confidently integrate CEPPA into their processes for permanent flame retardant polyester modification. Its applications span from high-performance polyester chips, filaments, and staple fibers to various textile and film applications. By partnering with a reputable manufacturer like NINGBO INNO PHARMCHEM, you gain access to not only high-quality CEPPA but also the technical support needed to optimize its use.
