NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing comprehensive information about the chemical products we supply, including Diisononyl Phthalate (DINP). Understanding the chemical properties and safety aspects of DINP is crucial for manufacturers seeking to make informed decisions about its use. This article provides an overview of DINP's fundamental characteristics.

Diisononyl Phthalate (DINP) is a diester of phthalic acid and isononyl alcohol. Its chemical formula is C26H42O4. DINP is a member of the phthalate family of plasticizers, which are widely used to increase the flexibility, workability, and extensibility of plastics, particularly polyvinyl chloride (PVC). Structurally, DINP is characterized by branched alkyl chains of nine carbon atoms, contributing to its higher molecular weight and specific performance attributes.

Key chemical properties of DINP include its appearance as a colorless, odorless liquid. It exhibits low volatility, meaning it evaporates very slowly, which is critical for maintaining the plasticizer's presence and effectiveness in the polymer matrix over time. This property directly translates to improved permanence and reduced migration of the plasticizer from the finished product. DINP also possesses good thermal stability and resistance to degradation, allowing it to withstand processing temperatures and environmental exposure.

In terms of performance characteristics, DINP offers excellent compatibility with PVC, enabling it to be easily incorporated into formulations. It provides good resistance to aging, water, and extraction, ensuring that products remain flexible and durable under various conditions. Furthermore, DINP exhibits good electrical insulation properties, making it suitable for applications such as wire and cable insulation. When comparing DINP to other plasticizers, these properties often position it as a superior choice for demanding applications.

The safety profile of DINP has been extensively studied by regulatory bodies worldwide. While it is a phthalate, DINP generally has a more favorable safety profile compared to some lower molecular weight phthalates that have faced significant restrictions due to health concerns. Regulatory agencies have evaluated DINP and have not typically classified it as reprotoxic. This has contributed to its widespread acceptance and continued use in a variety of consumer and industrial products. Manufacturers seeking to buy DINP can find detailed safety data sheets (SDS) from reputable suppliers like NINGBO INNO PHARMCHEM CO.,LTD. that outline handling precautions and regulatory information.

In summary, DINP is a high-performance plasticizer characterized by its low volatility, excellent compatibility with PVC, good aging resistance, and favorable safety profile. These attributes make it an ideal choice for manufacturers in diverse industries, from automotive and construction to electronics and consumer goods. NINGBO INNO PHARMCHEM CO.,LTD. supplies high-quality DINP, supporting industries in achieving superior product performance and compliance.
