We will exhibit Oji's cellulose nanofiber at the "2024 NAGOYA Automotive Technology Exhibition."

It is a natural-derived high-performance additive that has functions such as high viscosity and high transparency, which are superior to conventional additives.

"AUROVISCO" is a water dispersion of ultra-fine wood fiber cellulose nanofiber (CNF) with a fiber width of 3nm. By adding just a small amount to water-based liquid agents, the following outstanding functions are expected to be imparted. <Functions> - High transparency - High viscosity - dispersion stability - Water retention - Coating stability function - Thixotropic <Applications> - Thickening and dispersing agents for paints and inks: dispersion stability of pigments and additives / coating film stability - Cleaning and disinfectant solutions: dispersion of abrasives, etc., and coating film stability after application of liquid agents - Ceramic products such as concrete: reinforcement effect for ceramic products *The Oji Group has adopted the "phosphate esterification method" as an effective technique to reduce the energy used for fine processing during manufacturing. This method enables the production of high-quality (high transparency, high viscosity, thixotropic) cellulose nanofibers with higher production efficiency compared to conventional methods. In 2017, the cellulose nanofiber production facility began operation at the Oji Paper Tomioka Plant.

• Concrete admixture

Biomass content over 80% - Transparent, high-strength sheets made primarily of cellulose nanofibers / Further enhancement of functionality through composite with other materials!

The cellulose nanofiber transparent sheet "AUROVEIL" boasts glass-like transparency and dimensional stability while being made from wood-based materials. Additionally, it features high strength, high elasticity, and good flexibility. ■ Features of "AUROVEIL" - High transparency / High strength / High elasticity / Flexibility / High dimensional stability - Biomass content: Approximately 80% (depending on required functions and specifications, please contact us for details) ■ Composite Cellulose Nanofiber Sheet We have established a technology to combine cellulose nanofiber sheets (AUROVEIL) with resins such as "polycarbonate" and "acrylic." This environmentally friendly composite material reduces the use of fossil-based and plastic materials while leveraging the characteristics of each material. * "Cellulose nanofiber" refers to fibers that have been finely disassembled to the nano level (one millionth of a millimeter) from cellulose, the main component of wood. It is said to be a "dream new material" that is one-fifth the weight of steel yet possesses more than five times its strength. Being plant-based, it is also attracting attention as a sustainable resource.

New rubber products for the carbon-neutral era. Natural rubber × natural materials: cellulose nanofiber rubber composite CNF masterbatch.

This is a rubber composite masterbatch that combines unique phosphoric acid esterified CNF and natural rubber. Even with a small amount of addition, it improves elasticity and provides excellent strength and elongation, making it an environmentally friendly material that is expected to reduce the amount of carbon black derived from petroleum. <Features> Biomass Material... By replacing carbon black, the ratio of natural materials increases. Enhanced Functionality... Hardness and elongation comparable to or exceeding that of carbon black. Energy Saving & Durability... Increased durability is expected due to effects such as improved strength. Design Flexibility... The milky white masterbatch allows for consideration of colorful variations. Customization... We also accept requests for compatibility with synthetic rubbers such as NBR and HNBR, as well as optimization of fiber shapes. * "Cellulose Nanofiber" refers to fibers that have been finely disassembled to the nano level (one millionth of a millimeter) from cellulose, the main component of wood.

On November 20, 2025 (Thursday) and December 2, 2025 (Tuesday) from 11:00 to 14:00, our representative, certified public accountant and tax accountant Koichi Yokoyama, will be speaking at a free webinar hosted by Otsuka Shokai. He will explain important points to note regarding the revised Construction Business Act. [Construction Business Act / Public Works Optimization Promotion Act] - Prevention of omissions in the description of construction contracts - Obligation to notify "risk" information before contract signing by the contractor - Mutual exchange of original copies of construction contracts - Digitization of estimates, contracts, and order forms/acceptance letters We are entering an era where contracts must be documented in writing and stored electronically. Paperlogic is fully committed to supporting companies that have begun the transition from paper to digital.

Fujikohsuhou Co., Ltd. will hold a free online seminar titled "Laser Hardening Data by Material Type" on Wednesday, November 19, 2025. There are various materials that are easy or difficult to harden in laser hardening. We provide a simple explanation of the reasons behind this. This seminar will be a useful reference for design engineers considering laser hardening during the design phase. 【Recommended for】 ■ Those who want to know about materials commonly used in laser hardening ■ Those who want to understand the hardening characteristics of various materials

"We want to improve our operations with AI, but what exactly can we do...?" For those who want to actually try out and compare services, we have an announcement. The electronic contract and document management service paperlogic will be exhibiting at the 'Business Innovation Fair 2025 Autumn in Makuhari' hosted by Otsuka Shokai on November 13th (Thursday) and 14th (Friday) at the Hotel Green Tower Makuhari. Seminars on business improvement and AI utilization will also be held, so if you are nearby, please come and visit us. ● We will also be conducting product demonstrations of paperlogic at the venue. The biggest feature of paperlogic is that it is easy to operate and simple, yet it complies with all document management regulations, including the Electronic Books Act. We invite you to experience this simplicity firsthand.

1. "A New Era of Disaster Prevention and Mitigation Opened by Satellite Remote Sensing" Satellite remote sensing is a technology that uses sensors mounted on artificial satellites to acquire information about the Earth's surface over a wide area. In this presentation, we will outline the basic mechanisms and characteristics of remote sensing and introduce specific case studies of its application in the field of disaster prevention and mitigation. Furthermore, through examples of the latest satellite data applications, we will discuss future technological prospects and social possibilities.
