LIPPER

Bio Rubber Reinforced Material
LIPPER(NR100-18)
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-scooters as a substitute for carbon black, producing environmentallyfriendly tires that maintain tire performance. In an environmentally-conscious society, mobility
demands innovative eco-friendly tires. We contribute to the production of tires for a new era thatmeets the needs of society, new regulations, and people's values.

LIPPER(NR100-18) is designed toimprove tire performance
By blending LIPPER(NR100-18), a bio-rubber reinforcing material,with cellulose nanofibers at 3% to 6% in a tire rubber compound,tire performance and environmental performance can be improved.
It simultaneously achieves the durability required for tires, thereduction of power consumption required for electric mobility, thereduction of CO2 emissions, and the reduction of environmental
impact caused by tire wear dust.

Environmental performance
Replacing petroleum-derived carbon black withLIPPER(NR100-18), which is derived from natural
materials, will contribute to the reduction of CO2emissions. This will result in a tire suitable for ecofriendly micromobility.

Abrasion performance
The results of our driving tests show high performancefor wear resistance, i.e. the basic performance of the tire.
The amount of wear is reduced, resulting in tires with alonger cruising range.

Power Consumption PerformanceWith respect to the energy efficiency required of tires in
the age of electric mobility, LIPPER(NR100-18)
contributes to improved performance. It produces a highrolling performance tire with 20-30% better performance.

Strong colored tires
One of the weak points of conventional colored tires istheir low durability. By using LIPPER(NR100-18) as areinforcing material without carbon black, colored tires
can be achieved while maintaining tire performance.

In 2040, the world's tires will be white again!

Since Dr. Goodrich's invention of carbon black tires, the era of blacktires has lasted for more than 100 years. Now, LIPPER(NR100-18)
can be used to help maintain and improve the functional
performance of tires while reducing the use of petroleum-basedcarbon black. We envision a future where the world's tires will once
again be white and clean by 2040.

Cutting-Edge Technology

Tire Innovation throughNanotechnology
LIPPER(NR100-18) is a next-generation tire reinforcing material
made from wood and using nanotechnology. It is a rubber reinforcing
material with a high biomass content that can be added to naturaland synthetic rubbers to improve rubber properties.
One nanometer is a measure equal to one
millionthofamillimeter,whilenanotechnology
referstothe
manipulation of matter on an atomic andmolecular scale. LIPPER(NR100-18) wascreated using this technology, widely
considered a field poised for major
growth in the 21st century.

Beyond carbon black
In conventional technology, rubber was strengthened by adding
carbon black to natural or synthetic rubber. The use ofLIPPER(NR100-18) now makes it possible to strengthen rubber
while producing freely color-colored rubber products.
This image depicts nanofibers (white)entangled with rubber molecules (yellow)
to increase tire strength.

This photo shows a prototype tire for an eScooter. After completing the running test,
this photo clearly shows the difference in thedegree of wear between Prototype 1 without
LIPPER(NR100-18) and the results ofrunning with LIPPER(NR100-18).

Point of Note
An increased biomass content is associated with a reduction in
CO2 emissions and contributes to a carbon-neutral society.

Towards Walkable Cities

LIPPER

http://lipper.io

Walkable cities are cities and ideas designed around pedestrian andlow-speed mobility. Increasingly, emphasis is being placed on theconvenience of being able to get anywhere on foot, bicycle, or by
public transportation without a car, and on having an environmentthat is both enjoyable and safe to walk in. The environmental
performance of micromobility, as a familiar and accessible mode oftransport, is expected to increase in demand going forward.

Effectiveness Verification

TIRE PERFORMANCE
LIPPER(NR100-18)
The resilience modulus is improved and compression set is
reduced as shown in the table below. In running tests of 3F 5.5" Escooter solid tires with 16% addition of this bio-rubber
reinforcement, the amount of wear was reduced by about 50% andthe driving distance was increased by about 25%.
1F --- Bio rubber reinforced material 0% (CNF ratio 0%)
2F --- Bio-rubber reinforced material: 8% (CNF ratio: 3%)
3F --- Bio rubber reinforced material 16% (CNF ratio 6%)

Impacts

Protects rich marine resources andcontributes to CO2 reduction
LIPPER(NR100-18) is a tire with a high biomass material ratio,
which makes it strong without petroleum-derived carbon black.
It also reduces environmental impact by improving
biodegradability of tire wear dust.

Microplastics

80% reduction expected(5 million tons per year of tire dust)

CO2 emissions

80% reduction expected(Percentage of carbon content in tire)
Exact Scope 3 emissions are under calculation.
We are currently in the process of obtaining certification and carbon credit support.

Microplastic Issue
TRWP : Tire Road Wear Particles
Microplastics are microscopic plastic
particles measuring less than 5 mm indiameter. 53% of microplastics found in
the oceans are reported to have originatedfrom tires.
In 2018, the European and American
Gastroenterological
Associations
announced that microplastic fragments
are being consumed by humans via marineorganisms.

Movement to initiate regulation
In Europe, new regulations are being
introduced due to concerns about
environmental impact. The European
Commission has already indicated plans toestablish new regulations addressing dust
from tire wear.
