Product Usage
Dioctyl phthalate is a versatile general purpose plasticizer primarily applied in the processing of polyvinyl chloride (PVC) to enhance the flexibility of finished products. It features excellent compatibility with a wide range of PVC products, including films, artificial leather, cables and hoses. Furthermore, it can be used as a stationary phase for gas chromatography and for the performance testing of high efficiency filters. Qualified food grade and medical compliant grades are also suitable for the production of food and medical packaging materials.
