Liquid Farnesene Rubber Bio-based liquid rubber Kuraray has expanded its liquid rubber portfolio with liquid farnesene rubber, a product based on natural and renewable materials. It contains a polymerized form of beta-farnesene, a bio-based monomer. Liquid farnesene rubber functions like a reactive plasticizer, but has a much higher molecular weight than normal plasticizers. The co-vulcanizable material signifi- cantly reduces migration, which improves the durability of rubber compounds. Its use during the rubber compounding stage significantly reduces processing time while maintaining the physical properties of rubber compounds. This results in lower processing costs.
