The Union of Polymeric and Chemical Industriy of Pardis began its operations in August, 1990, under the name of the Union of Plastic and Nylon.Due to the low number of campus unions compared to Tehran, the city's Supervisory Commission decided that homogeneous job classes would be incorporated into existing unions, following the same ordinance as UPVC, medical, paint and thinner. And… also joined the Plastic and Nylon Union.To honor these loved ones and prevent further problems, the proposal to rename the Union to the Union of Polymer and Chemical Industries was taken to the County Guild Supervision Commission by the board of directors, and finally, after the approval of the Tehran Province Guild Supervision Commission, the proposal was approved.
