KURARAY LIR-290 by Kuraray is a liquid hydrogenated isoprene rubber. It functions as a reactive plasticizer but have far higher molecular weight than normal plasticizer. It is co-vulcanizable with solid rubber such as IIR, SBS, SIS, SEBS and SEPS. It reduces migration significantly which improves the product’s shelf life. 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 without halogen residuals. Improves tack and adhesive properties in a wide range of temperatures. Shows superior heat and weather resistance. KURARAY LIR-290 is commonly used in hot melts adhesives.
