Kuraray Liquid Rubber

Kuraray Liquid Rubber (K-LR) includes Liquid Isoprene Rubber (LIR) and Liquid Butadiene Rubber (LBR). These high-viscosity synthetic rubbers are based on isoprene, butadiene and styrene. They are colorless, transparent and almost entirely odorless, with low VOC’s.

Kuraray’s liquid rubber grades function as reactive plasticizers but have far higher molecular weight than normal plasticizers. They are co-vulcanizable and reduce migration significantly which improves the product’s shelf life.

Using K-LR during the rubber compounding phase significantly reduces processing time, while maintaining the rubber compounds’ physical properties. This results in a product with lower processing costs.

The functionalized grades can be bonded to a wide variety of matrices for improved performance.

Common applications include tires, belts, hoses and other rubber goods. In addition, K-LR is used to produce high performance coatings, adhesives and sealants.
