KURARAY LIQUID RUBBER
- General name
- Liquid rubber
- Sales format
- Liquid
High-viscosity synthetic rubber KURARAY LIQUID RUBBER products are based on isoprene, butadiene and styrene. They are colorless, transparent, almost entirely odorless and low VOC. Functionalized grades are available as reactive plasticizers with far higher molecular weight than normal plasticizers. They are co-vulcanizable and significantly reduce migration.
