We have commenced our occupation as one of the first major sellers and distributors of raw material and additives with application in plastic, specifically Masterbatches in 1978.
In 1989, with the round-the-clock efforts and preservance of our managers and engineers, IRCO Masterbatch compamy started its activity as one of the first masterbatch producers in Iran. After theat and by changing our brand name to Corbi Polymer, we have always followed a path of progress until today. We are also proud that in 2018, with the opening of the new phase of Corbi Polymer factories, in addition to increasing the production capacity, we also introduced new products to the wide range of our products.
