In the manufacturing of PVC films and sheets, achieving the right balance of flexibility, clarity, and durability is paramount. Diisononyl Phthalate (DINP) has established itself as a key plasticizer in this sector, offering distinct advantages that contribute to superior product quality. NINGBO INNO PHARMCHEM CO.,LTD, a leading chemical supplier in China, provides high-purity DINP tailored for these demanding applications.

PVC films and sheets are utilized across a vast range of industries, from packaging and agriculture to construction and medical devices. The inherent rigidity of PVC necessitates the use of plasticizers to impart the required flexibility and workability. DINP excels in this role by effectively reducing the glass transition temperature of PVC, making the material softer and more pliable. One of the critical advantages of DINP over other plasticizers, such as DOP, is its lower volatility. This characteristic ensures that the plasticizer remains within the film or sheet structure during processing and throughout the product's lifespan, preventing embrittlement and maintaining flexibility over time. This is especially important for films used in packaging, where maintaining product integrity is crucial.

Moreover, DINP provides excellent resistance to extraction. Whether the film is used for food packaging, stationery, or protective coverings, its ability to resist migration when in contact with liquids, oils, or even aggressive cleaning agents ensures product integrity and safety. This resistance is vital for maintaining the film's mechanical properties and preventing contamination. The processing characteristics of DINP are also highly favorable. It offers good compatibility with PVC resins, leading to stable viscosity during processing steps like calendering and extrusion. This results in uniform film thickness, enhanced surface finish, and reduced processing defects, contributing to higher yields and lower manufacturing costs. The clarity of films and sheets plasticized with DINP is also noteworthy, making it suitable for applications where visual appeal is important.
