The vulcanization properties of hybrid elastomeric materials based on waste rubber powder

Abstract

Elastomeric materials have viscoelastic properties and can be designed for numerous applications, tires production, vibration isolation and damping. These properties can be tailored for a wide temperature range and in ozone-rich atmospheres. Processing capacity of a rubber compound can be predicted by their vulcanization properties. In goals of raising environmental demands rubber manufacturers are now focusing on the uses of recycled product. Re-use, recycle, pyrolysis and recovery are the common methods in sustainable management of waste elastomeric products. Waste rubber can be used in civil engineering, for composite material preparation, as energy source, for sport devices, tires fabrication. The goal of this applicative work was to estimate vulcanization behavior of rubber compounds based on recycled rubber powder and triple rubber matrix NR/BR/SBR which is used for tire tread manufacturing. It was estimated that the values of optimum vulcanization time decrease with the increase of recycled rubber powder amount.
