Bis(2-ethylhexyl) phthalate (DEHP/DOP) is a widely used phthalate plasticizer for improving the flexibility, durability, and processability of polymers. It is primarily used in PVC manufacturing, including flexible cables, wires, flooring materials, artificial leather, films, coatings, hoses, sealants, and other plastic products. It is also applied as a plasticizing agent in rubber, adhesives, and synthetic materials due to its excellent compatibility with PVC resins and good low-temperature performance.
