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.

Features and benefits
▪ Adhesives, coatings, sealants ▪ Rubber compounding ▪ Mobility ▪ Sporting goods & footwear
▪ Bio-based material ▪ Good plasticizing effect ▪ Low migration
▪ Low tan δ over a wide temperature range ▪ Excellent softening effect at low tempe- rature (low Tg) ▪ Less entanglement between mo lecules ▪ High reactivity of branched double bonds ▪ High molecular weight and low viscosity
* For certain applications, liquid farnesene rubber cannot be introduced due to raw material supply relations. Please contact our sales representatives.
