Preparation and study of properties of polyvinyl chloride-scrap tire composite for civil applications

Polymeric compounds based on thermoplastic elastomer styrene-butadiene-styrene block copolymers and siliconic rubber powder

“…[1][2][3] In general, these rubber post-production wastes are grounded and sieved when rubber powder is obtained (with rubber particles of a certain size), and then the rubber powder obtained is used in the rubber and plastics industry to obtain composites intended for various applications such as: shoe soles, windshield wipers, housings, trolley wheels for transport, mats for of gyms and playgrounds, bicycle pedals, etc. [3][4][5][6][7] Several studies have been performed on the use of rubber powder as a filler in the production of polymeric composites with thermoplastic matrix, in which the thermoplastic materials used were: polypropylene (PP), 8 high density polyethylene (HDPE), 9 ethylene vinyl acetate copolymer (EVA), 10 polyamide, thermoplastic polyurethane 5 , polyvinyl chloride, 11,12 etc. These polymer composites can be processed into finished products by specific methods of plastics, and their mechanical properties depend on the type of polymer matrix used, the nature of the interactions between the thermoplastic matrix and rubber powder, the type and size of rubber granules, the obtaining method of rubber powder (by cryogenic grinding or at room temperature), the amount of rubber powder in composites, etc.…”
