Recycled polypropylene in granules
Polypropylene is the most popular polymer today. In the total volume of world production of industrial raw materials, it occupies 20%. This material has a unique structure that allows products made from it to restore their original shape after minor deformations. Polypropylene is produced in granules, which is the most convenient form for its further use in the production process. Secondary polypropylene granules are in great demand on the modern market, which have a lower cost, and at the same time, are not inferior in properties to the primary raw material.
