NINGBO INNO PHARMCHEM CO.,LTD. is committed to delivering Dibutyl Phthalate (DBP) of exceptional quality, characterized by stringent technical specifications and high purity levels. These attributes are critical for ensuring optimal performance in the diverse industrial applications where DBP is employed, from plasticizers for PVC to components in paints, adhesives, and printing inks.
The key specifications for DBP typically include its appearance, which is a clear, transparent liquid, and its ester content, which NINGBO INNO PHARMCHEM CO.,LTD. maintains at a minimum of 99.5%. This high ester content is indicative of the chemical's purity and effectiveness as a plasticizer. Other critical parameters that are meticulously controlled include acid value, moisture content, and chromaticity (measured in Pt-Co units). A low acid value and minimal moisture content are essential for preventing unwanted reactions and ensuring product stability during storage and use.
The relative density and refractive index are also important physical properties that are carefully monitored. These values serve as benchmarks for confirming the identity and purity of the DBP. For instance, the typical relative density at 20°C is around 1.044-1.045, and the refractive index at 20°C/D is approximately 1.493-1.495. NINGBO INNO PHARMCHEM CO.,LTD. ensures that its DBP consistently falls within these precise ranges.
The flash point, a measure of the substance's flammability, is another crucial safety and handling parameter. With a flash point typically at or above 160°C, DBP presents a relatively low fire hazard under normal handling conditions. This safety profile, combined with its technical efficacy, makes it a preferred choice for many industrial processes.
By adhering to these rigorous technical specifications and maintaining high purity, NINGBO INNO PHARMCHEM CO.,LTD. ensures that its Dibutyl Phthalate is a reliable and high-performing chemical intermediate. This commitment to quality is vital for supporting the manufacturing processes of clients across various sectors, reinforcing DBP's role as a versatile and indispensable industrial chemical.
