- It is co-vulcanizable with solid rubber such as NR, IR, IIR, SBR and BR.
- It reduces migration which improves the product’s shelf life.
- It offers strong tack and adhesive properties in a wide range of temperatures.
- It enhances processability and exhibits low glass transition temperature.
- During the rubber compounding phase, it significantly reduces processing time and energy consumption while maintaining the rubber compounds physical properties.
