What is Dioctyl Phthalate (DOP)?
DOP is the most widely used general-purpose plasticizer for PVC. It provides excellent flexibility, low-temperature performance, and processing characteristics at an economical cost.
How it works
Inserts between PVC polymer chains, reducing intermolecular forces and increasing flexibility, workability, and distensibility.
