Success Stories

A new, effective method for producing thermoplastic dynamic vulcanizates (TDVs) from polymer wastes was developed under STCU Project #3009 (financed by UIE for EURO 252,000) by the Institute of Macromolecular Chemistry (Ukraine) jointly with the Institute of Nuclear Physics (Uzbekistan). This method proposed thermal, mechanical and chemical reclamation of crumb rubber (viz. ground tire rubber, GTR) and its reuse in combination with recycled polyolefin wastes to produce composite materials. High performance of TDVs produced from recycled polyolefins and GTR is achieved through discontinuous (inner mixer) and continuous (extrusion) production methods. The TDVs of optimal composition are characterized by high tensile strength (12-13 MPa), high elongation at break (500-800%), high thermal, frost, ageing and chemical resistance, as well as high stability to multiple reprocessing.
