Behsa Polymer Pars Company was founded by a group of university professors, elites and university graduates with the aim of creating a revolution in the production of engineering polymer alloys, masterbatches and additives required by the plastic industry, as well as biodegradable polymers and additives. Special conditions in the production of special polymer products, including mixing technology and advanced formulations, have required the acquisition of superior technologies. Based on this, relying on internal expertise and inspiration from the latest technologies of the world, the first asymmetric nider device in the world was designed and built in this company.
