Product Usage
Dioctyl phthalate, a versatile general-purpose plasticizer, is primarily employed in the processing of polyvinyl chloride (PVC) to improve the flexibility of finished products. It is widely compatible with various PVC items, including films, artificial leather, cables, and hoses. Additionally, it is used in gas chromatography stationary phases and in the performance testing of high-efficiency filters. Certain compliant grades are also suitable for the production of food and medical packaging materials.
