KURARAY LIR-310

KURARAY LIR-310 by Kuraray is a liquid rubber based on isoprene block copolymer. It can function as a reactive plasticizer but have a far higher molecular weight than normal plasticizers. It is a high-viscosity synthetic rubber grade. It is co-vulcanizable with solid rubber such as NR, SBR, BR, IR and IIR. During the rubber compounding phase, it significantly reduces processing time while maintaining the rubber compounds’ physical properties. It results in a product with lower processing costs. It is colorless, transparent and odorless with low VOC. Its low glass transition temperature (Tg) improves low-temperature properties. KURARAY LIR-310 is used in coatings.
