Lignin-Reinforced Rubber Composites

Lignin is one of the most abundant bio-based polymers which is discarded as waste in the pulp and paper industry in very large amounts. Production of rubber/lignin compounds is discussed in this chapter as a promising approach for the development of value-added products from lignin. Challenges facing the successful production of such compounds have also been explained along with common modification techniques from the literature. Effects of addition of lignin on the network structure, mechanical properties, and physical characteristics of rubbers such as their oil resistance and surface adhesion are included in this chapter. Lignin is also introduced as an interesting stabilizer for polymers, especially elastomers.
