Compatibilization of Polymeric Composition Filled with Ground Tire Rubber – Short Review

Abstract

Waste rubber is recognized as a valuable materials resource and searching for new recycling methods is the main activity of many research institutions and companies. During last years only few scientific papers concerning foamed polymer compositions filled with ground tire rubber were published. The paper reviews the progress in compatibilization and foaming of polymeric compositions filled with a ground tire rubber.

Phase morphology, mechanical, and thermal properties of fiber-reinforced thermoplastic elastomer: Effects of blend composition and compatibilization

“…The interaction of the maleic anhydride group (MAPE) with the hydroxyl group on the carbon black surface or carboxyl groups of RR may be responsible for interfacial interaction between rubber and compatibilizer. 44,45 It is also reported that possible reaction between zinc oxide (ZnO) as a component of RR (Table 3) with maleic anhydride (MA) during melt mixing can be responsible for the tensile strength improvement of compatibilized TPE blends. 46…”
