DEHP is a manufactured chemical that makes plastic more flexible. Its primary use is as one of several plasticisers in polyvinyl chloride resins used for fabricating flexible vinyl products. It is used to detect leaks in protective face gear, and as a test material for filtration systems. It has also been reported as being used as a replacement for polychlorinated biphenyls (PCBs) in dielectric fluids for electric capacitors and in vacuum pumps.
