Influence of pyrolysis temperature on biochar properties: Applications as a reinforcing filler in sbr and epdm elastomeric compounds

Year: 2024

Type: article

Abstract: This study investigates the effect of pyrolysis temperature on the properties of biochar derived from Pinus spp. wood waste and its application as a reinforcing filler in styrene-butadiene rubber (SBR) and ethylene-propylene-diene monomer (EPDM) elastomeric compounds. Biochar was produced at 400°C and 900°C and its effects on the mechanical properties of the elastomers were analyzed. The results indicate that biochar produced at 900°C has higher fixed carbon content and lower volatile matter, resulting in improved mechanical properties such as tensile strength and elongation at break compared to biochar produced at 400°C. Despite a lower specific surface area, the irregular surface structure of biochar enhances its interaction with elastomers, providing a semi-reinforcement. This study highlights the potential of high-temperature biochar as a sustainable alternative to conventional fillers such as carbon black, contributing to the development of environmentally friendly materials from biomass waste. The results support further exploration of the role of biochar in elastomer applications, highlighting its environmental and mechanical benefits.
