Is DEHP and PVC the same?

DEHP: A softener for polyvinyl chloride (PVC), a plastic polymer used in a wide array of products. Unplasticized PVC is hard and brittle at room temperature. A plasticizer (softener) is typically added to increase the flexibility of the polymer. DEHP is the plasticizer for most PVC medical devices.
