Liquid Farnesene Rubber Bio-based liquid rubber
Kuraray has expanded its liquid rubber portfolio with liquid farnesene rubber, a prod- uct based on natural and renewable materials. It contains a polymerized form of be- ta-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-vul- canizable material significantly reduces migration, which improves the durability of rub- ber compounds. Its use during the rubber compounding stage significantly reduces pro- cessing time while maintaining the physical properties of rubber compounds. This results in lower processing costs.
