Liquid farnesene rubber<\/h1>\n\n\n\n

With liquid farnesene rubber, Kuraray is expanding its portfolio of liquid rubbers with a product based on natural and renewable raw materials. It contains a polymerized form of beta-farnesene, a bio-based monomer.<\/p>\n\n\n\n

Liquid farnesene rubber functions like a reactive plasticizer, but has a much higher molecular weight than normal plasticizers. The co-vulcanizable material significantly 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. Lower processing costs are the result.<\/p>\n\n\n\n

As an additive in rubber compounds, liquid farnesene rubber gives them high plasticity. The material also retains excellent flexibility at low temperatures and improves ice grip. It is therefore currently used mainly in winter tires, where it increases ice grip while preventing the rubber compounds from hardening over time. The performance of the tire is thus maintained over the long term.<\/p>\n<\/div>\n\n\n\n

How it’s made<\/h2>\n\n\n\n

Liquid farnesene rubber is based on beta-farnesene, a renewable monomer derived from sugar cane. Using established fermentation processes, proprietary yeast strains convert sugar sources such as sugar cane into beta-farnesene. Liquid farnesene rubber is synthesized from the base monomer by polymerization.<\/p>\n\n\n\n

With liquid farnesene rubber, a new family of polymers is created that has unique performance and offers the opportunity to broaden the range of applications for this class of materials. Liquid farnesene rubberthus represents a new pathway to bio-based polymers.<\/p>\n\n\n\n

Liquid farnesene rubber is available as homopolymer type (100% beta-farnesene) and as random copolymer type (with a beta-farnesene portion and a crude oil portion). The homopolymer type has a higher molecular weight (130,000) than the two random copolymer types (30,000 and 100,000, respectively). In terms of viscosity, the types differ significantly: homopolymer type (69 Pa\u2022s at 38 \u00b0C) and random copolymer types (12 and 603 Pa\u2022s at 38 \u00b0C, respectively).<\/p>\n<\/div>\n\n\n\n
