Bio-rubber reinforced material LIPPER(NR100-18) is a masterbatch rubber with 18% cellulose nanofibers highly dispersed in natural rubber. This masterbatch rubber can be blended in tire rubber formulations for bicycles and e-scotters as a substitute for carbon black to produce environmentally friendly tires that maintain tire performance. Mobility appropriate for an environmentally oriented society requires innovative environmental tires. We contribute to the production of tires for a new era that meets the needs of society, new regulations, and people’s values.
